FLOODLIGHTING INCLUDING SEARCHLIGHT & AIRPORT LIGHTING GENERAL ELECTRIC COMPANY SCHENECTADY, N. Y. GEA-161-A Supersedes GEA-161 Introduction utility and lofty ideals of beauty. Artificial light has become not only a potent and necessary tool of industry and commerce, but, as well, an efficient auxiliary , \HE modern practice of electric illumination has established new standards of of decorative and architectural art. The illuminating engineer, supplementing the rigid exactitude of science with a sympathetic appreciation of form and color, is exercising a profound influence on almost every activity of life—from the ordinary routine of its work to many of its finest delights. These aspects of present-day illumination find vivid and distinguished expression in the art of floodlighting. Its field of service extends from the freight yard and wharf to the splendid creations of the architect’s genius. It expedites, by night, the work of the builder and protects the completed structure from marauders who depend on the cover of darkness. From an unseen source, it silvers the temples of government, of finance, and of commerce, searching out every beauty of line and decoration, suspending them, as It were, in exquisite relief against the dark sky, and giving new emphasis to the material fabrics and to the public functions which they symbolize. Under its beams, monuments to great men and to great causes convey their message at night as well as by day; the spectacular aspects of nature—massed foliage or mighty waterfall—preserve their charm during the hours when men are free to enjoy them; and, with more intimate touch, community playgrounds are made available, when the day’s work is done, for the common recreation and the health that comes with open-air play. Floodlighting has also made possible the effective illumination of outdoor pageants, carnivals, and other spectacles, and has thus given new encouragement to a colorful art that is yearly growing in public appreciation. Perhaps the most conspicuous triumphs of floodlighting during the last fifteen years have been at national and international expositions. Men and women, by hundreds of thousands, have carried away as their most vivid impression the glory of color that trans- figured pallid buildings and sculpture, and summoned into nightly bloom a vast flower ~ of many-hued flame. It is difficult to realize that the art which thus adorned the Panama- Pacific Exposition and which adds a flood of color to the flow of Niagara Falls is the same that safeguards the making up of a freight train or facilitates the unloading of a barge. It is only by contrasting these extremes that one can appreciate the immense scope of floodlighting in its many commercial and artistic aspects—that one can understand its important place as a constructive aid to the advance of industry and culture. The General Electric Company has erected specially equipped laboratories in which lighting specialists, engineers and artists devote their skill and experience to new accom- plishments in the technique of floodlighting—to new applications and new effects. A few of these results are pictured and described on the following pages, and a brief review is offered of the principal types of projectors in which profound research has embodied a brilliantly creative service.

No. 3049414 DESCRIPTION This projector is constructed of non-ferrous material. The door frame, casing, and trunnion bracket are of special aluminum alloy. It is equipped with a servicing device which consists of a large brass tube that screws into a brass base plate; and asmaller tube, assembled to the trunnion bracket, which slides inside of the larger tube. The smaller tube is slotted and fitted with three bayonet joints. These engage a stop screw which is assembled into the larger tube and projects inside it. The projector may be raised or lowered so that it can be lifted above the surface of the water in the fountain in order that the front door may be removed and the device serviced or relamped. The front-door glass is gasketed by rubber packing, and the door casting is gasketed against the casing. The projector has a 34-in. pipe-tapped hole mid- way of the casing for a 34-in. pipe nipple through which the lead cable passes. A wiped joint can be made between the brass bushing and the lead cable. The device is also provided with two other 34-in. tapped holes to which a drain pipe, which may be a rubber hose or a flexible lead cable, can be attached. The reason for the two holes is that when the projector is set with the beam in the vertical position the bottom hole can be used for draining away any condensation which may occur inside of the projector. This also permits atmos- pheric pressure always to be maintained within the projector. If the projector is used with the beam horizontal or nearly so, the plug in the top hole can be removed and put into the bottom hole and the drain pipe can then be put into the hole from which the plug was removed. It is very advisable when installing these projectors to put the drain pipe in because it is desirable that atmospheric pressure be maintained. Otherwise the heat from the lamp will change the density of the air inside the projector, and, when the lamp is turned off and the projector cools, there is a tendency toward a vacuum or, at least, a lower air pressure. This is likely to create a breathing effect and may, under some circumstances, cause water to enter the projector. A sliding screw focusing mechanism is provided which allows the lamp to be moved along the axis of the reflector either up or down by pulling or pushing the bulb. The 16-in. glass reflector is silver plated and coated with electrolitically deposited copper. Either the 500-watt or 1000-watt, 110-volt floodlighting lamp may be used.

APPLICATION Briefly, a floodlighting projector consists of a reflector and socket mounted in a weatherproof casing and arranged to take a focus-type MAzpA lamp. The socket can be moved forward or backward in order to focus the lamp; when the proper focus is obtained, the socket can be locked in position. All parts are readily accessible, and the units are weatherproof and can be mounted either outdoors or indoors. It is possible economically and effectively to illuminate surfaces where lighting by the ordinary method of employing several lamps and reflectors is impractical. Following are a few of the uses of floodlighting: Floodlighting Public Buildings, Monuments, Fountains, etc. Every municipality has some notable example of archi- tecture, a statue, a square, or historical place in which the com- munity has considerable pride. The floodlighting projector makes possible the illumination of any such structure and gives it prominence by night. Floodlighting Billboards and Signs G-E floodlighting projectors for billboard lighting can be installed in practically any convenient place; obviating the use of complicated wiring, increasing the working hours of the billboard, and enhancing the advertising value through the contrast of the bright surface against the dark background of night. Floodlighting in Construction Work Wherever contractors are called upon to do construction work at night they will find G-E floodlighting projectors of considerable assistance. Temporary installations can be easily and quickly made. Floodlighting for Protection Important railroad bridges, docks, power stations, aqueducts, reservoirs, etc. that are nightly guarded against mischief-makers and prowlers are much more completely protected when G-E floodlighting projectors are used. Floodlighting of Winter Sports For lighting winter carnivals, toboggan slides, skating ponds, hockey, curling, and skating rinks, the G-E floodlighting projector is particularly useful because it provides a powerful light and obviates the necessity of poles which often become dangerous obstructions. Floodlighting for Pageants The floodlighting projector is inherently suited to the lighting of pageants, carnivals, outdoor expositions, displays during merchants’ weeks, etc. Floodlighting Athletic Grounds Floodlights, mounted on poles adjacent to the grounds or on the tops of the stands and buildings of the grounds, have made it possible to hold athletic meets and to play football and baseball games at night.

Location, residential section. Units must be installed 25 ft. from surface to be illuminated. What type of floodlighting unit, foot-candle intensity, and number of units are required? FORMULA FOR NUMBER OF PROJECTORS N =Number of projectors. —AXE}A =Area of building facade. L_ |) E=Foot-candle intensity required. L =Beam lumens delivered by one projector. N SOLUTION OF PROBLEM Factors given: Working distance, 25 ft.; surroundings, residential section; surface of building, light. (8000 sq. ft.) Refer to the formula for beam diameter in feet given above and at a working distance of 25 ft. The L-3 projector is selected because its beam covers a large area, being a wide angle pro- jector and it proves to be the most economical projector for this application. The table of intensities shows that a light-colored surface in a residential section requires 5 foot-candles. Refer to formula Ne AXE A=8000; E=5; L=3270 N __ 8000 (sq. ft. area) X 5 (foot-candles) 3270 (beam lumens—Form L-3) N = 12.2, or 12 projectors Reasonable allowance should be made for overlapping of beams so as to produce an adequate and even illumination over the area to be floodlighted. Beam diameter can be determined from formula above. The illuminating engineering laboratory of the General Electric Company will give floodlighting recommendations con- cerning objects to be illuminated upon receipt of further data as follows: Size and color. Distance between objects. Locations suitable for projectors. Nature of lighting in the vicinity. LAMP DATA LIGHT MAXIMUM BULB LIFE it STD .

This movement of freight cars is continuous and anything which tends to expedite this movement with a decreased breakage and theft loss and with less chance of danger to the train operators is of the utmost importance not only to the railroads, but also to our economic life. Statistics compiled by some of our larger railroad systems prove the many advantages of proper lighting of the railroad yard. The Committee on Illumination of the Association of Railroad Electric Engineers in November, 1923, reported the following advantages of yard lighting: [1 0 (1) (2) Speeding up of cars handled in the yard at night. Reduction in cars damaged by rough handling and collision in the classification, yard with consequent reduction in claims, delay in delivery of goods, loss of service of damaged cars, etc. Reduction in losses due to pilfering, on account of more effective policing possible in a well-illumi- nated yard. (4) Improved working conditions and increased safety for employees working in the yard. The importance of these benefits is evidenced by the fact that certain railroads have during the past year authorized relatively large expenditures for improved yard illumination. ] (3) NOVALUX FLOODLIGHTING PROJECTORS FORMS L-22, L-24, AND L-25 APPLICATION (Cont'd) GENERAL REQUIREMENTS In past years both pendent units and floodlighting pro- jectors have been utilized for this service but at the present time opinion is almost universal that the most effective results are to be obtained by the use of floodlighting projectors. The requirements of a projector for service in the railroad yard are most severe. Satisfactory results can be obtained only with projectors which have been designed and constructed for this specific duty. Material Because of the fact that injurious gases from the smoke of the locomotives are ever present in the railroad yard, it is most important that the material from which the unit is constructed be impervious to attack from these gases. The units Fig. 3 (Photo No. 277378) Form L-24 Floodlighting Projector With Visor are at all times exposed to the weather and should, therefore, be weatherproof and of a material which does not rust. These two requirements indicate that a cast aluminum alloy construction would be most suitable. Mechanical Details The projectors are as arule mounted on high towers where space for the electrician or maintenance man is limited. In many cases the platform from which these men must operate is at the rear of the unit and in such cases it is most impor- tant that they be able to relamp or clean the projector from the rear without changing the direction of the beam. The best way to provide for this is by the use of a unit which has a hinged back door. Photometric Results The determining factor on the quantity of light in the yard is the value of beam lumens from the projector; con- sequently careful consideration should be given to the efficiency of the unit. Since in many cases the throw is 1000 ft. or more, the unit must have a high value of central beam candle power. Towers and space in the railroad yard are very expensive and anything that can be done to reduce the number of projectors necessary to light a given area is a most important consideration. With the above-mentioned points in mind, the engineers of the General Electric Company have developed railroad yard lighting projectors which possess all these advantages, as may be observed from an examination of the construction specifications listed below. Because of their high lighting efficiency these projectors are most economical. They are suitable for intensive large- Fig. 4 (Photo No. 277397) Form L-25 Floodlighting Projector With Visor area lighting and are particularly adapted for the lighting of railroad yards and the floodlighting of large buildings and signs. Standard 110-or 220-volt, 750- to 1000-watt, general service (base up) burning lamps can be used in the L-22 and L-24 projectors while the 110-volt, 1000-watt (base down) burning floodlighting lamp can be used in the L-25 projector. The most economical results are obtained with the larger lamps. RECOMMENDATIONS It is not recommended that the L-22 projector be used for railroad yard lighting unless it is desired to use the 1500-watt lamp. This is essentially a large-area unit. The L-24 and L-25 projectors are better adapted for railroad yards on account of being dustproof, but must never be used with lamps exceeding 1000 watts capacity. CONSTRUCTION The units have a cone-shaped, two-part casing of alumi- num alloy and a hinged front door and a hinged rear section for relamping or cleaning, from the back of the pro- jector, without disturbing the direction of the beam. The focusing mechanism is of the split ball and socket type with retarding spring and single clamping screw, allowing movement of the socket in any direction. This movement is absolutely necessary in order to focus accurately the lamp. The retarding spring prevents lamp breakage and further facilitates focusing. [16] NOVALUX FLOODLIGHTING PROJECTORS FORMS L-22, L-24, AND L-25 CONSTRUCTION (Cont'd) The L-22 projector is provided with shielded outlets at the top and bottom for ventilation and can use the 1500-watt lamp. The L-24 and L-25 projectors are totally enclosed. The L-22 and L-24 projectors have the lamp socket at the top arranged for base-up burning lamps while the L-25 pro- jector has the lamp socket at the bottom arranged for base- down burning lamp. Each projector is provided with two reflectors; the front unit, of patented parabolic shape, is attached to the stationary part of the projector; the rear unit, of shallow para- bolic and spherical sections, is attached to the movable rear door. These reflectors are of blown glass, silvered and hermeti- cally sealed by a heavy coating of electrolytic copper which entirely envelops the outer surface of the mirror. The copper coating, in addition to protecting the glass, assists in radiating the heat from the lamp. This particular design of composite reflector gives a greatly increased value of central beam candle power and beam lumens over other comparable projectors. The front door is fitted with heat-resisting, pressed glass, either clear or lightly stippled. The light stipple in the glass tends to smooth out any high spots in the beam. The casing and door of the projector are of cast aluminum; the ventilating cowl is of copper. All screws and bolts are of non-rusting materials. The trunnion bracket is band iron, heavily lead plated. The swivel and base are cast-iron, heavily lead plated. This trunnion bracket and swiveled base allow the adjustment of the beam in any direction. All joints are made weatherproof by the use of sponge- rubber gaskets. HOW TO FOCUS In focusing, care should be taken to see that the center of the lamp filament is in the exact center of the rear reflector. It is also important that the filament be brought into the focal point along the horizontal axis at right angles to the adjust- ment mentioned above.

NOVALUX INCANDESCENT SEARCHLIGHTS APPLICATION Novalux incandescent searchlights are designed for pro- jecting beams of light upon distant objects by the use of high-current incandescent lamps. They are particularly applicable to illumination of construction work, spectacular displays, or long distance floodlighting, in addition to the usual uses on board ship for picking up buoys, and in emer- gencies. The 18-in. searchlight uses lamps of 900, 1000, 1200, or 1500 watts where the maximum beam candle power is desired. It can also be furnished with diverging doors for spreading the beam in one plane to angles of 10, 20, 30, and 40 degrees. The 12-in. searchlights were especially designed for use on 75-foot power boats, similar to those used by the New York Harbor Police and U.S. Coast Guard. The power available on these boats is limited to the capacity of the storage battery. As no ventilation is provided, the maximum lamp wattage recommended is 600. Two types of control are furnished, hand and pilot-house. The hand-control is used where it is convenient for the operator to stand at the searchlight and train the beam. The pilot-house control is for operation from inside a pilot house or shelter. The swivel and trunnion mounting is used where the searchlight beam is fixed in location and does not need to be changed frequently, ILLUMINATION The following table and charts give the illumination produced by these searchlights with the several lamp and reflector combinations.

Searchlight with Silvered-glass Mirror INCANDESCENT LAMPS The table on Page 16 shows the incandescent lamps which may be used with the searchlights. For maximum candle power, it is recommended that the lamps of lower voltages be used, as in these lamps a higher concentration of filament is obtained. However, they have @ :isve short life and where replacement cost must be considered, as in applications where continuous burning is necessary, lamps which have a longer life are recommended. The 110- to 125-volt lamps may be operated directly from standard commercial circuits while transformers or resistances are listed for operation of the low-voltage lamps. CONSTRUCTION 18-IN. SEARCHLIGHTS The 18-in. searchlights are of cast-iron and sheet-steel construction treated with black japan. A ventilating dome is located at the top of the drum. The door is of heat-resisting glass mounted in a cast-iron frame and attached to the drum by swing bolts. Focusing of the lamp with respect to the mirror may be accomplished outside of the drum by means of a knurled knob at the rear. Handles are provided at the rear of the hand-control searchlight, to train the beam in azimuth and elevation. The glass reflector is 18-in. in diameter and is made to conform with U.S. Navy specifications. The sil- vering is protected by electrolytic copper backing. Mechanical injury to the mirror is prevented by a sheet-steel dome attached to the rear of the drum. The pilot house control allows movement of the beam to be accomplished by means of a single handle, projecting through the pilot-house roof. The beam is elevated or de- pressed by a circular rack and pinion. 12-IN. SEARCHLIGHTS The 12-in. searchlights are made for marine service, the castings being of a non-corrosive aluminum alloy. The drum is a single casting to which the frame for the front-door glass is attached by hinges. This glass is heat resisting, being convex to provide additional strength. A rubber gasket is placed between the door frame and the drum. A universal focusing mechanism is provided so that the lamp may be focused in the mirror from outside of the drum. [21] 36-IN.

DESCRIPTION Boundary lights are used to mark the boundaries of aviation fields so that oncoming pilots can see a pattern of the field. They are spaced approximately 250 feet apart. Where any quantity is required, it is advisable to use a constant- current system, with No. 8 A.W.G parkway cable. However, multiple sockets are listed for use where series circuits are not advisable. Clear and inside-etched globes are used for boundary markers. Ruby globes are used for obstruction markers, —--—---—-—- #- ~ —_— being placed on pole lines and the highest points of build- ings which are considered obstructions to taking off or landing. Green globes are placed to indicate the most favorable approaches to the field. The base is usually buried in the ground to a depth of about 18 inches and secured with crushed stone or concrete. For the series system, current is supplied by a constant-current transformer, either station or pole type. Lamp not included ie— in Cat.
