Y. Introduction RNAMENTAL Novalux Units are architecturally decorative street-lighting fix- tures designed for use with Mazpa lamps. Mazpa lamps for street lighting are made in many sizes to operate either in series or multiple on alternating or direct current. The light from them is steady in value and warm in tone; therefore Novalux units have a wide and distinct field of application. The flexibility with which these units can be used and the many attractive designs in which they are built make them highly desirable where a “family” plan of street lighting is adopted. Experience shows that, in the long run, the most satisfactory street-lighting systems both with respect to cost and effectiveness are those which have been carried out con- sistently in accordance with some definite and comprehensive plan. Such plans usually provide a family of ornamental units similar in design but different in size for the business streets, parks, boulevards, and principal residential sections. The type of unit to be used, the kind of lamp, the height of the standards, and the distance between them, all depend upon the size of the city, width and importance of the street, the character of the road surface and adjacent buildings, the amount of trees and shrubbery, and finally the local systems of distributing electricity. Each city presents an individual problem in street lighting. To combine effect and economy in the solution of this problem ordinarily requires that a street-lighting specialist carefully study the conditions and then make recom- mendations for the installation. Novalux units are made in such a variety of sizes and designs that from them may be selected a complete family which will maintain architectural uniformity from the blazing white way in the center of the city to the quiet residential districts in the suburbs. Each unit is designed upon artistically and technically correct principles. Simplicity lends grace of outline and ease of maintenance; strength gives durability. In size and texture the glassware used is such as to give perfect diffusion with minimum absorption of light. General Electric Novalux Units are designed with a broad experience in the require- ments of street illumination and are backed by the reputation of a company which has always led in the manufacture of all the necessary apparatus, from generator to lamp. The Ornamental Novalux Unit does not include the standard which supports the unit, the Mazpa lamp, or a Type IL transformer which, if used, is mounted in the bottom of the standard or buried in the ground. It does, however, include a properly insulated lamp receptacle with an auto-transformer when necessary, the diffusing globe, and the casing which fits the top of the pole. THREE Form 8—No. 39 Globe Form 8 MALL, simple, and compact, the Form Eight Orna- mental Novalux Unit may be mounted on slender standards for white-way lighting in towns and villages and for lighting the less important business streets of larger cities. This unit has been designed especially for use with 1000- to 600o-lumen, 6.6-ampere, series or 200- to 1000- watt multiple Mazpa C lamps. Since the Form Eight casing will not contain an auto-transformer, high current series lamps can be used in this unit only in connection with a Type IL transformer at the base of the standard. Externally the casing is decorated with a simple design architecturally in harmony with fluted and reeded standards. Within the casing two cast lugs support a porcelain socket which holds the lamp receptacle. The globe seat is embodied in the top of the casing, the globe being held in place by three set screws, while the bottom of the casing is made to fit the top of the standard. A few parts are assembled to make a simple unit, durable and dependable. The Form Eight casing fits a pole with a top four inches in diameter, and is made in four types, practically the same in appearance but differing in method of attachment to the standard and in the diameter of the globe seat. When equipped with a Number 39 Genco globe and glass canopy, the unit has a very attractive appearance at night, the globe being so designed as to be filled completely with light from the casing to the top of the canopy. The diffusing glass used in the globe is of such a density as com- pletely to suppress the unpleasant glare of the naked filament. The resulting effect is a soft glow with light thrown upward against the building facades as well as downward upon the streets. The glass canopy is distinctly a Novalux achievement which adds greatly to the beauty of the units at night. However, if desired, an aluminum canopy may be had in- stead. With the aluminum canopy a reflector is placed inside FOUR and at the top of the globe to direct downward and make useful some of the light which would otherwise be wasted in the canopy. It is obvious that less light is available for illuminating the upper stories of buildings along the street when a metal canopy is used, than with one of glass. The quality of the glass used with ornamental street lighting units is of great importance in determining the ultimate attractiveness and efh- ciency of the installation. With this in mind, the General Electric Company 1s offering alabaster rippled globes and canopies for use on_ its street lighting units. Rippled glass diffuses the light by breaking it up and passing it through an external flashing of opal. The surface is covered with little ridges and furrows so that the appearance of the units equipped with this glass is quite different from that of those having the ordinary diffusing globes, Form 8—No. 109 Globe Form 8—No. 109 Globe the sparkling light from the rippled surfaces suggesting life and motion. Rippled glass is very effective in preventing glare, absorbs so little light that it is the most efficient type of diffusing glassware, and its delicate glitter is most pleasing both by day and night. The Number tog alabaster rippled globe and canopy are one of the most pleasing glassware combinations available for use on an ornamental lighting unit. It is of the same shape as the Number 39 Genco globe but is made of the rippled glass which gives a very desirable dash and brilliance to the installation. A metal canopy can be used instead of glass if so desired. The Number 123 alabaster rippled globe and canopy were produced in response to the demand for a design of more classical lines. The lower opening has been reduced in order to pre- FIVE vent, as much as possible, the loss of light in the bottom of the globe, and to improve the appear- ance of the unit as a whole. The canopy and the globe are held together by an ornamental band of perforated brass, and the canopy 1s supported independently of the globe so that breakage of the latter does not mean destruction also of the former. Though it is larger than the units previ- ously described, the delicate outlines and sparkling surface of the Number 123 globe make it one of unrivaled beauty. The Number 103 Polycase globe and canopy is the same size and shape as the Number 123. It is, however, made of a smooth translucent dif- fusing glass instead of the alabaster rippled glass. A slight variation in shape is available in the Number 127 globe used with the Number 1127 canopy. Each is made of the alabaster rippled glass; Form 8—No. 123 Globe however, a metal canopy can be furnished if desired. Holophane Dome Refractors are applicable to all Novalux units excepting those equipped with the plain white diffusing globe, the character of which renders their use ineffective. The Dome refractor redirects most of the upward light to the street and sidewalk surfaces in equal proportions, while the A-syM-ETRIC Dome refractor confines a greater portion to the street surface and less to the sidewalk. The sacri- fice in the amount of upward light incurred by the use of either type of refractor is of little importance, inasmuch as they are usually installed only on boulevards or residential streets, where the resulting effect is excellent. In all Novalux units, a flat metal ring is fastened to the upper edge of the globe by means of screw clamps, and forms a rigid support for the adjustable refractor holder. The cast aluminum pinnacle is threaded to a steel rod which extends Form 8—No. 118 Globe SIX upward from the refractor support, and the enclosing canopy is thereby clamped _ securely between the pinnacle and the globe. Globes on street lighting units serve a three- fold purpose. In the first place they diffuse the light. The modern series Mazpa lamps of over 2500 lumens have such an intense concentration of light in the short filament that to look directly at them is as blinding as to look at the sun. To have these high-power lamps exposed 1s painful and injurious to the eyes. A diffusing globe, how- ever, acts as a secondary light source, conceals the filament, and reduces a most distressing glare to a comfortable glow. The kind of glass used for the globe is important from the stand- point of diffusion. Too often, diffusion is obtained at a great sacrifice in illumination. The best results are obtained only through a carefully balanced Form 8—No. 39 Globe selection of glassware and globe size. Alabaster rippled glass probably gives the best diffusion for the least absorption, and in general the globe size should be large for light sources of high intensity. The second use of the globe is to protect the lamp and receptacle. The glass of the lamp becomes hot in operation and will then crack if touched by a cold raindrop. It may also break if struck by hail. In winter, the globe protects the lamp and receptacle from snow and ice. Finally, the globe serves a decorative purpose. It carries out the architectural lines of the standard. It surmounts the necessarily substantial pole with an equally substantial unit. Its use adds sparkle to the light and reduces glare. SEVEN Form 9—No. 37 Globe Form 9 HE Form Nine Novalux Unit is designed for more intensive white-way lighting than is possible with the Form Eight, which makes it suitable for the main business streets of large cities. The casing is designed to contain an auto-transformer so that high-current series Mazpa C lamps up to 15,000 lumens may be used with the unit as well as the straight series and multiple lamps. The Form Nine unit is designed to have as few parts as possible; it consists simply of a casing, a porcelain insulat- ing plate which acts as a socket for the receptacle, a globe, and a canopy. Where an auto-transformer is used, it 1s fastened to the under side of the porcelain insulating plate. The external design of the casing is such as may be appropriately used with a round, fluted, or reeded standard. The casing fits standards with tops about six and one- half inches in diameter, and is designed to support globes considerably larger than those of the Form Eight. When equipped with a Number 37 Genco globe and glass canopy, this unit is recommended for white-way lighting using Mazpa C series lamps of 6000- and 10,000-lumen sizes. The globe is shaped almost exactly like the Number 39 Genco globe; it 1s, however, somewhat larger in order properly to diffuse the light from the larger lamps that may be used with the Form Nine units. If desired, a metal canopy and reflector may be had for the Number 37 Genco globe instead of the glass canopy. The Number 107 alabaster rippled globe is the same shape and size as the preceding globe. The rippled glass is made by adding a medium flashing of opal to the outer surface of a clear rippled glass, which produces a combination of sparkle and soft diffusion unequaled in any other globe. Not only is the rippled glass exceptionally attractive when lighted from within, but it also has an excellent appearance by daylight. EIGHT Either a glass canopy to match the globe or a metal canopy with a reflector may be used. The Eight-panel diffusing globe is recom- mended for the largest Mazpa lamps, 10,000 or 15,000 lumens, for white-way lighting in the largest cities. The distribution of light from this unit is such that it provides an equal amount of illumina- tion tor the street surface and the building fronts. This globe is very impressive in appearance and is of the highest decorative value. The globe is built up of eight panels of diffusing glass held in an iron frame. Each glass panel is curved so that the entire globe is round. ; : The panels are fastened in place against felt a strips by spring clips so that the unit 1s weather- proof and dust-proof, and any one panel may be replaced when broken without disturbing the others. A flat metal reflector suspended in the Form g—No. 90 Eight-panel Globe canopy above the lamp prevents loss of light in the top. The canopy is hinged so that it may be swung back to gain access to the interior for cleaning or renewing the lamp. The globe, com- plete, with its framework and canopy can be removed from the casing if desired as it is held in place by set screws. The Number 118 alabaster rippled globe is an all-glass unit of the same general contour as the Eight-panel globe. It finds a wide use in white-way lighting. This unit is less ornate than the paneled one, but has a slightly higher efficiency due to the freedom from metal ribs, and the smaller top and bottom openings. Either a metal or a glass canopy may be used. For use where upward light is very undesir- able, all rippled glass units can be equipped with Holophane dome refractors which turn the up- Form 9—No. 118 Globe ward light down on the street. NINE The glass and metal canopies supplied with all except paneled globes are fastened in place by a rod which passes down through the center of the canopy to a framework inside the globe. The rod terminates outside of the globe in an ornamental knob. When it is necessary to renew a lamp, the rod is partially unscrewed which allows the canopy to be moved to one side, leaving the globe open, after which the refractor, if one is used, can be removed, and then the bulb. The Mazpa series lamps of 4000-, 6000-, and 10,000-lumens are much more efficient when operated at 15 and 20 amperes than at the 6.6 amperes of the standard series circuit. It is to take advantage of the greater efficiency of the high-current lamps that the Form Nine and other large Novalux units have been designed to con- tain an auto-transformer. ETT ogy Ost gg C1008 If, in connection with high-current lamps it is desired to protect everything above the ground-line from high voltages, a Type IL transformer should be used instead of the auto-transformer. The Type IL trans- former is an individual lamp insulating transformer which is used to adapt 15- and 20-ampere lamps to 6.6-ampere circuits. The Eight-panel Globes, the Number 39, 109, 37, and 107 globes, are derived from forms originally used with arc lights. They are now made in rippled glass and with glass canopies if desired; and they may be used to replace or supplement arc lights with similar globes without destroying architectural uniformity. The other globes and the lanterns are for use with Mazpa lamps. The Number 92, 97, and 118 globes are derived from the eight-panel units. The Number 103, 123, 104, and 124 globes are urn-shaped in outline and are especially adapted for all glass construction. The great variety of globes and casings gives combinations which make Novalux units available for every requirement. SIN) Form 12 HE Form 12 Ornamental Novalux Unit is one of the best of the recent contributions to decorative street lighting. The first ornamental units were © ponderous and inefficient, with massive and over-decorated standards; the more recent designs are slender and unob- trusive. The diffusion of the light is effective and its distribu- tion is efficient; globes are gracefully shaped and beautifully finished. The Form 12 unit 1s a splendid representative of the new type of street-lighting units. The same internal parts are used in the casing as in the Form g. The socket 1s mounted upon an insulating plate which rests upon lugs in the casing, and in the auto-trans- former types the coil is fastened to the under side of the insulator. The casing, designed for a pole having a five-inch top diameter, is made in two parts: the casing proper, and an adapter or globe seat. The adapter, made in three sizes to fit different globes, holds them firmly and gently; four screws placed go degrees apart bear upon spring steel fingers which in turn clamp the lower lip of the globe, holding it securely in place and eliminating any danger of breakage in tightening the screws. The graceful lines of the Number 123 globe produce a very pleasing effect and the rippled glass gives the lowest absorption compatible with perfect diffusion. The upper part of the globe is a separate glass canopy held to the globe by an ornamental perforated brass band. The bottom opening has been reduced to the minimum to prevent loss of light and to improve the appearance of the globe. The Number 103 Polycase globe is identical with the Number 123 except that a smooth diffusing glass is used in place of the alabaster rippled glass. Neither the Number 103 nor the 123 globes can be used with adapters that are designed to receive auto-transformers. Where large lamps are to be used, large globes are required to obtain the proper diffusion and to radiate the heat generated by the lamp. The Number 124 alabaster rippled globe is the same as the Number 123 except that it is larger and the adapter will contain an auto-transformer; hence, it can ELEVEN Form 12—No. 104 Globe be used with high-current series lamps. The Number 104 Polycase globe, except that it is not made of rippled glass, is identical with the Number 124. The Number 118 alabaster rippled globe, though slightly less decorative than the others for the Form 12 unit, is excellent for white-way lighting. The shape is similar to that of the Eight- panel globes. It may be had with a glass or a metal canopy and with or without an auto-transformer. The Number 97 Genco globe corresponds in every way with the Number 118, differing only in being made of plain diffusing glass. The Form 12 unit can also be equipped with the Number 126 alabaster rippled globe, which is especially designed for use with the 25,000- lumen Mazpa “C” lamp. An alabaster rippled Form 12—No. 118 Globe glass or metal canopy can be furnished. Any of the rippled glass globes for the Form 12 unit can be supplied with Holophane dome refractors. The Number 118, 123, and 124 globes are the same size and shape respectively as the Number 97, 103, and 104; but the former are made of alabaster rippled glass. In the Form 12 unit a single casing, designed for a standard with a five-inch top diameter, 1s made to fit a great variety of large and small globes by means of four different adapters or globe seats. This makes the Form 12 unit available for both primary and secondary business streets by merely using a different adapter and globe; for instance, the Number 124 globe can be used on the principal business streets and the Number 123 globe, which is exactly the same in design, is appropriate on the less important streets. Form 12—No. 104 Globe TWELVE Form 13 HE Form 13 unit carries the same graceful lines as the Form 12, but is slightly smaller, and, like the Form 8, is particularly adapted to white-way lighting in towns, villages, and the secondary business streets of large cities. It should be used with 4000- and 6000-lumen series or 300- and 400-watt multiple Mazpa lamps. The casing is the same internally as the Form 8; a very simple porcelain socket rests on two lugs on the inside and forms a support for the lamp receptacle. An auto-transformer cannot be used. Architecturally the casing is in accord with an octagonal standard or other of simple design having a four- inch diameter at the top. A globe seat is embodied in the casing, the globe being held by three spring steel fingers actuated by set screws. The Number 92 Genco globe has very small top and bottom openings; hence, the light lost is small. Either a metal or a glass canopy is furnished, no internal reflector being necessary. The Number 127 globe is made of alabaster rippled glass and is somewhat larger than the Number g2 globe. It is equally artistic and can be supplied with either the alabaster rippled glass or metal canopy. From time to time street lighting units must be opened for cleaning and replacing lamps. Novalux units have been designed to make this as simple an operation as possible. In most of them access to the interior is made possible by the removal of the canopy, which means that the main globe does not have to be lifted from its seat. This greatly reduces the risk of breakage through careless handling. The canopy on most globes is removed by unscrewing the ornamental knob at the top. On some globes the per- forated brass band which holds the canopy in place is removed, and in the eight-panel globes the canopy is hinged in place. All the globes are easy to open even when covered with snow and ice. THIRTEEN Form 13—WNo. 127 Globe Form 16—WNo. 37 Globe Form 16 HE Form 16 unit is a replica of the Form 13 on a larger scale. The same severe and simple Flemish character appears in the casing design of both. The Form 16, however, is for use with 6000- to 10,000-lumen series or 400- to 1000-watt multiple Mazpa C lamps. It should be used for the white ways in larger cities when the Form 13 1s used for the secondary business streets. A combination of these two units makes it possible to cover a wide range in lamp intensities without sacrificing uniformity of appearance. In the construction of the Form 16, the same internal parts are used as in the Form g. A porcelain insulating plate rests on two lugs inside the casing and acts as a base for the socket. When an auto-transformer is used, it is fastened to the under side of this plate. The Form 16 Novalux unit can be used with a variety of globes and canopies. When used with the Number 97 Genco globe it may have either a glass or a metal canopy. The same shape when made of alabaster rippled glass is known as the Number 107 globe, which likewise may be had with either a metal canopy or a complete rippled glass unit, with the highest efficiency and unequaled appearance. The rippled glass by virtue of the irregularities in its surface is an almost perfect diffusing medium, only a light flashing of opal being necessary to prevent glare. Rippled glass also adds sparkle and brilliance to the unit by day as well as by night. Moreover, when the rippled surface becomes dusty, the first rain running down the furrows washes them out and does not leave the glass soiled and streaked in appearance. The Number 97 Genco globe corresponds in form to the Number 92 Genco globe used on the Form 13 unit but is larger. It may be had with either a metal or a glass canopy. The Number 118 alabaster rippled globe is the same as used on the Form g unit and is the same size and shape as the Number 97. It may be had with either a glass or a metal canopy. FOURTEEN Units with rippled glass globes may be equip- ped with a Holophane dome refractor which gives somewhat better distribution for parkway and boulevard lighting. Auxiliary transformers are coming into exten- sive use with constant-current ornamental street- lighting systems. In general these are divided into two types: auto-transformers and Type IL trans- formers. The former are a part of the unit and are supplied with it when required; the latter are separate transformers. Auto-transformers are mounted in the casings of certain ornamental units. They serve to increase the current of the series circuit from 6.6 amperes to 15 or 20 amperes for use with the high- current Mazpa lamps. These transformers do not insulate the lamp from the high-current Form 16—No. 118 Globe which may occur in the series circuit; therefore they do not give any additional protection to the installation or safety to persons coming in contact with it. The Type IL transformer can be used with any Novalux unit. It is ordinarily located in the base of the standard, buried in the ground, or placed in a manhole. It serves the double purpose of increasing the current and acting as an insula- tor. This makes it very useful for supplying 15 or 20 amperes to high-efficiency lamps from the standard series circuits. As an insulator this transformer gives the maximum safety, it being unnecessary to have any high voltage circuits above the ground level. The Type IL trans- former also protects the lamps from surges in the line, a seventy-five per cent increase in primary current giving only a forty- five per cent increase Form 16—No. 107 Globe in secondary current. FIFTEEN Form 17 HE Form 17 unit is radically different in design from the Novalux street lights already described; consequently, its application covers a somewhat different field. It is offered as a means of securing an attrac- tive and efficient installation with particularly low upkeep. A single piece of porcelain acts as a combined insulator, reflector, and socket-holder. The complete fixture consists of a heart-shaped pipe support from the top of which is suspended the all-porcelain unit glazed white underneath on the radial reflecting surface and green above where it is exposed to the weather. A remov- able iron top canopy gives easy access to internal binding posts in the porcelain insulator from which leads are run through the supports. At the bottom of the unit, the supports are joined to a heavy casting which fits a standard with a six- inch top and in which there is a covered handhole in order that the leads from the fixture may be attached to the line wires. The Form 17 unit, on account of its heavy porcelain insulator, is particularly suited for straight series lamps, but the type of diffusion employed limits the size of these lamps to 2500 lumens and below. The unit can not be equipped with an auto-transformer for high-current lamps. The porcelain reflector distributes the light in such a way that most of it falls on the street surface, with little at higher angles. The characteristics of the globeless unit which recom- mend it very highly for the lighting of boulevards, parkways, and residential districts are briefly as follows: Very low main- tenance cost due to the accessibility of all parts and the absence of expensive globes which are easily broken in handling or in a spirit of mischief; very high efficiency because there is no glassware to absorb a portion of the light from the lamp; a distribution which insures no upward light in the windows of residences; insulation that will stand a 25,000-volt test. SIXTEEN If desired, the Form 17 Novalux may be had with a Holophane band refractor surrounding the lamp. This redirects the light from the higher angles to the lower, insuring more uniform illu- mination of the street surface and less light on the upstairs windows facing the street. Refractors, of course, decrease the efficiency of the units, but in some installations the improved distribution warrants their use. Where glassware is desired for use with this unit, the attractive Number 143 alabaster rippled globe can be furnished. This harmonizes architec- turally with the heart-shaped pipe supports, pre- sents a very pleasing appearance, and provides a uniform diffusion of the light. A felt gasket between the globe and reflector prevents the entrance of moisture and dust. Economy, efficiency, and durability combined with attractive appearance make the Form 17 $? rN a0 Form 17—No. 143 Globe unit desirable for a highly practical street lighting installation wherever intense illumina- tion 1s not necessary. The use of refractors is recommended only where very definite results are desired by special distribution of light. When refractors are used it is very important that the fila- ment of the lamp be at the exact light center of the globe and refractor. If it is not, the distribution of light may vary widely from that which the refractor was designed to accomplish, the resultant illumination being very different from that desired. Novalux units have been particularly designed for use with Mazpa lamps. This means that the receptacles are arranged so that the filaments of Mazpa lamps will in every case occupy the light center of the globe and be in proper position to give the correct distribution if a refractor is employed. SEVENTEEN Form 18 Form 18 HE Form 18 Novalux lanterns are made of the best grade of cast iron or aluminum from machine patterns and all parts fit in their respective places without any more fabricating than the drilling of holes. The corners are cast sharp and the surfaces smooth, bringing out a beauty of detail which is almost impossible to obtain with bent or punched pieces of lighter material. The different parts are held together with brass screws, nuts, and lock washers eliminating any chance of the corrosion of tapped holes, a feature which will be appreciated by maintenance MGS No loose panel doors have been provided in these units, the lamp being reached by throwing back the top canopy. To make the unit dustproof, the canopy is made to rest against a padded surface. At the factory all castings are given one coat of black japan which is ample protection till the units are installed when they may be painted as desired. The lantern can be crated disassembled thus reducing the cost of boxing and the cubical contents of the container, which is of impor- tance in making foreign shipments. The two sizes in which the Form 18 Novalux lantern is available meet every requirement of ornamental street light- ing besides being very useful for the ornamental lighting of certain types of buildings. The larger size can be equipped with auto-transformers for high-current series lamps in sizes up to 15,000 lumens. Both the large and the small lantern can be used with the straight series and multiple lamps or with a Type IL transformer. The lamps in these units burn with the tip up. Eight flat glass panels are required for the sides and eight more for the top of this unit. Spring clamps hold these panels against soft felt cushions which reduce the danger of breakage and make the unit dustproof and weatherproof. This unit is ordinarily equipped with granite opalescent pressed glass panels; however, they can be supplied with alabaster rippled glass panels at an increase in cost. EIGHTEEN Form 19 HE Lantern design is the oldest form of lighting unit. To this day it finds an important place in the lighting of most European cities, and is being used to some extent in America, for white-way and boulevard lighting. The Forms 18 and 19 Novalux are lantern type units differing from other American models in that they retain the ornamental projections which are a fundamental part of lantern design. The attempt to modernize the lantern by omitting this orna- mentation robs it of the very feature which lends it beauty and dignity. The ribs are extended grace- fully and the top canopy terminates in a slender pinnacle. These Novalux units are in architec- tural accord with the old standards of lantern design. The Form 19 Novalux unit is a lantern type Large Form 19 built for suspension from an ornamental bracket rather than for mounting on a standard. In design it corresponds to the Form 18 and is particularly intended for parkways, boule- vards, and residential districts in cities where the ornamental lantern-is used for the white ways. The castings are the same as for the Form 18 lantern with the exception of slight changes. The spiked pinnacle is replaced by a flexible suspension hook and cable box. The bottom of the lantern 1s a grid casting with false panels to provide light directly under the unit. In these pendent lanterns two sizes are made corresponding to the large and small Form 18 lanterns for mounting on ornamental standards. Two types of glass panels are also provided, alabaster rippled and diffusing glass. With the former a Holophane dome reflector can be used if desired. The small size Form 1g unit is designed for 300- to s00-watt multiple lamps, and the large size for 750- and 1000-watt multiple lamps. Series lamps should not be used with pendent lanterns. An important advantage of the lantern type of unit is the use of comparatively small, flat panels of glass, not easily broken in shipment or handling and readily replaceable at small cost. The item of globe breakage, including as it does the cost of boxing and shipping, is of such importance that it will outweigh other considerations in many cases. NINETEEN Form 23B Form 23 HE Form 23 Ornamental Novalux is a modest and and inconspicuous lantern-type unit suitable for either white-way or less intensive decorative lighting. In certain communities where colonial archi- tecture is the prevailing type, the severe straight lines of this lantern form the most artistic treatment for the lighting units. The Form 23 lantern is made in two sizes: A large one which can be provided with an auto-transformer and used with multiple, straight series, or high-current series Mazpa lamps for intensive lighting; and a small one for residential districts which cannot be had with an auto-transformer for high-current lamps. The top and bottom octagonal parts of the lantern frame are each made of one piece of cast bronze. The ribs for the sides and top are built of galvanized sheet steel with a cold-rolled copper veneer. All bolts for holding the glass panels are fastened to the inside of the steel ribs before the copper is put on, making them invisible from the outside. The eight glass panels are securely held in place by the ribs, giving a finished lantern which 1s made dust-proof and weather- proof by the use of felt gaskets. The cast bottom and top sections connected by steel ribs give the lantern such strength that it will easily stand the weight of a man without collaps- ing. Paint is not needed for protection as the outside of the paneling ribs, the top and bottom castings, and the orna- mental canopy are all made of copper or bronze; nor is it needed for decoration, as copper and bronze naturally weathered make a very beautiful finish in themselves. The freedom from the necessity of painting is, besides, a con- siderable additional saving in maintenance. Inside the unit a large copper reflector treated with aluminum bronze acts as a support for a dome refractor TWENTY which may be used if it is desired to throw a maximum of light on the street surface. In the large unit access to the interior for replacing the lamp is gained through a side panel which is hinged at the top and secured by a brass thumbscrew at the bottom. The canopy or hood is made of eight panels of clear rippled glass. The eight side panels are cut from flat sheets of granite opalescent pressed glass. In the small unit the canopy is made of sheet metal and is hinged at one side so that it may be thrown back for changing the globe or cleaning the interior. No hinged panel is necessary. The eight side panels are of alabaster rippled glass as in the large unit. In both the large and the small unit the lamps burn tip down. molded globe. Form 23B In respect to globe renewals, the lantern type unit has an obviously low maintenance cost inasmuch as the flat glass panels are quickly in- stalled and are less expensive than the blown or The lantern type of unit finds much favor as a decorative lighting fixture on_ buildings, bridges, gateways, and in other similar locations. The pendent type of lantern is very effective when suspended on brackets at either side of a doorway. The regular lantern type of unit, when mounted on suitable newels has been used with very great success in the decorative illumination of entrances to parks, estates, and cemeteries. When used in such locations it 1s often not advis- able to install lamps of the same high power as would be used in the lantern were it a part of an Form 234 intensive street-lighting system. TWENTY-ONE Form 24B Form 24 HE Form 24 Ornamental Novalux is a suspension-type lantern unit similar in size and design to the large Form 23 lantern for pole mounting. The original street lighting lanterns used years ago were generally of the suspension type, having been at first merely hand lanterns strung up over the street or hung by the doorways of houses. Modern lanterns modeled after the old patterns are also designed as suspension units and as such are particularly intended for hanging from orna- mental brackets. The main castings, ribs, and glass panels of the Form 24 pendent unit are interchangeable with those of the large Form 23 unit. Instead of a canopy at the top, however, a bayonet joint is provided by means of which the unit is suspended. At the bottom, eight glass panels allow the light to fall directly downward on the street below the lantern. One side panel, and the entire lower grid are mounted on hinges, thus greatly facilitating any adjustment or cleaning process. After removing the lamp, the entire lantern can be detached at the bayonet joint and removed, leaving the receptacle and wiring intact. Granite opalescent pressed glass panels are used throughout. The unit has an internal reflector and may be had with a Holophane dome refractor if desired. The Form 24 Novalux lantern is intended for use with 300- to 500-watt Mazpa multiple lamps. It cannot be used on series circuits except in connection with a Type IL transformer. The lamps burn with the tip down. TWENTY-TWO Form 25 HE Form 25 basket-type Novalux unit meets better than any other type the requirements of residential districts where the surroundings justify an ornamental treat- ment, where wide streets require curb mounting of the units rather than center span suspension, and where long spacings and high mountings are necessary to economize in the number of units used. The appearance of the basket-type unit is very pleasing. From a distance it seems to have a sectional paneled globe, but the construc- tion actually involves only a one-piece rippled glass globe supported by a basket formed of five copper bands. The rippled outer surface of the clear crystal globe not only produces a certain amount of diffusion but also gives life and sparkle to the light. The sparkle is also noticeable Form 25 on Bishop’s Crook in the daytime. The bracket type of mounting increases the utilization of light on the street surface and reduces the likelihood of interference from overhanging tree foliage. Moreover, lights placed out over the street rather than on one side back of the curb, illuminate both curbstones and assist 1n outlining the boundaries of the pavement. Such an arrangement provides a much better distribution of light over the entire street surface, particularly where it is wide, than a similar system of units suspended over the center of the street. The geographical extent of residential districts is so great that efficient light utilization becomes a serious problem. With staggered units far apart, each unit should be mounted high. Under these conditions, the dome refractor with which the unit is equipped provides a distribution of light which is admirably adapted to the requirements of residential streets. The top of the Form 25 unit is a single iron casting which supports the socket and porcelain enameled reflector, and to which the basket is hinged. The reflector also serves as a holder for the Holophane dome refractor. The globe is held tightly against a felt gasket to prevent the accumulation of dust or insects inside the unit. The dimensions of the unit are such that the heat from the largest lamps is dissipated without any special provisions for ventilation. The basketwork is not of such a size as materially to reduce the light on the street. TWENTY-THREE The unit is built in a large and a small size. The small size, using a Number 116 alabaster rippled globe, 1s recommended for staggered mounting at intervals of from 200 to 300 feet at a height of 16 feet on residential streets. It is intended for use with 100- to §00- watt multiple lamps or 1000-lumen straight series lamps. The large size, using a Number 108 alabaster rippled globe, is recommended for staggered mounting at intervals of from 300 to 400 feet at a height of 20 feet on residential thoroughfares. It is intended for use with 300- to 500-watt multiple lamps, 2500- to 6000-lumen straight series lamps, or 4000- to 10,000-lumen series lamps with Type IL transformer. The top castings of the basket type units are arranged to screw on the end of a one and Form 25 one-quarter-inch pipe. This makes them avail- able for use with the standard pipes and scrolls which are made in many forms for street system brackets. Brackets suitable for use with the Form 25 Novalux unit are built by the General . Electric Company in many forms. These are constructed from iron pipes bent in various shapes and supported by strap-iron scroll work. The wires leading to the lighting unit proper pass through the iron pipe which forms the main bracket. The insulation of this wire for use with series circuits should be at least equal to the maximum possible voltage in the circuit unless a Type IL transformer is used. All of the brackets are designed for fastening to poles with bolts or lag screws, but they may also be fastened to buildings or other supports. The Form 25 unit can be installed on existing brackets wherever it is desired to change from an open lamp with an enameled reflector to a more attractive type. The diffusing globe also makes it possible at the same time to increase the illumination by the use of larger lamps than would be possible without some means of concealing the glare of the naked lamp filament. TWENTY-FOUR Form 27 HE simple architectural beauty of the Form 27 unit, when mounted on a slender fluted or reeded standard, makes it ideal for white-way lighting in small towns or villages or for the minor business streets of larger cities. Its alabaster rippled glass globe and canopy are equally beautiful by day and night, sparkling in the sunshine or efficiently diffusing the glare of the lamp filament with a warm sparkling glow. A metal canopy can be furnished without materially detracting from the distinctive appear- ance. The Number 118 alabaster rippled glass globe and canopy are recommended for use with this unit, its artistic contours harmonizing so well with those of the casing that it is unques- tionably the most desirable combination. Form 27—No. 118 Globe This unit is especially adapted for use with 1000- to 6000-lumen 6.6-ampere series, or 200- to 1000-watt multiple Mazpa C lamps and, since the slender design of the casing does not permit the use of an auto-transformer, a Type IL series transformer is mounted in the base of the standard. Holophane Dome Refractors redirect a portion of the upward light to the street and sidewalk surfaces. They can be used with the Form 27 unit and are often desirable along boulevards, parkways, and residential streets, where the amount of upward light is of less importance. TWENTY-FIVE Summary of Units and Equipments The sketches of the units are drawn to scale in order to indicate size. In general the large units for intensive lighting are on the right, while the left-hand column contains the units for less powerful Mazpa lamps.

There are, however, several pole manufacturers who specialize in the construction of ornamental standards for G-E Novalux Units. The units illus- trated in this bulletin are typical of the various designs. They are usually constructed of cast-iron, pressed steel, or rein- forced concrete. Where tubular steel poles are already install- ed for the support of trolley wires, attractive brackets for Novalux street lighting units may be mounted on_ these poles. These brackets are available in a wide vari- ety of designs capable of accommodating the different Novalux units. The ornamental character of G-E Nova- lux Units renders them useful for the illumination of bridges, Form g Unit Mounted on Bracket gateways, building entrances, etc. For such installations, special brackets and standards, architecturally appropriate, can be furnished. Some cities have adopted a definite and comprehensive plan of street lighting, wherein fixtures of the same general design are employed for both business and_ residential districts. It is known as the “family” system, and maintains the desired architectural uniformity throughout the city, together with the assurance of adequate illumination. General Electric I]luminating Engineers are experts in the planning of modern street lighting installations. Their counsel is at the free service of every community.
