reason, it is important to avoid placing an excessive number of black-light units on any one circuit.

No. 10 B and S gauge is recommended for the wiring and the gauge should never be smaller than No. 12 B and S. Line voltage should be checked at the time of installation and the three-tap transformer included with quality blacklight equipment should be hooked up to meet local voltage conditions.

The Black-light Artist

Of course, the most carefully planned electrical installation cannot of itself assure the success of fluorescent murals. The purpose of the black light is solely to energize or bring to life the fluorescent materials used in the painting of the mural. The artist who works in the fluorescent medium is literally ffpainting with light." It is just as important for him to be liberal with his paint as for the electrician to provide plenty of black light. 7

The artist will find this new medium a challenge to his skill and his imagination. By selecting a subject which offers the fullest possibilities for fluorescent treatment and by resisting the temptation to overlay an ordinary picture with the fluorescent material, he can achieve effects which are completely impossible with ordinary colors. Always, of course, he should paint under black light and should try to approximate the actual level of illumination in the theatre where the mural is to be displayed.

Prefabricated Black-light Murals

Until very recently, the exhibitor who decided to use black-light murals was faced by the necessity of bringing together and effectively co-ordinating the skills of the architect, the electrical engineer and the artist. In many communities, this is no particular problem and the exhibitor may prefer to have the artist come in and paint his fluorescent murals directly on the walls of the theatre. On the other hand, there is now available a prefabricated mural and black-light combination, developed and produced by an entirely new technique,

making it as simple to install as the most conventional of theatre decorations.

Prefabricated fluorescent murals are offered in a variety of patterns or subjects, ranging from pictorial Scenes to formalistic designs. The exhibitor selects the picture he likes the best. It is delivered to him complete with the framing materials necessary for mounting it on the wall of his theatre. The package further includes black-light equipment designed and constructed especially for use with the particular mural he has purchased. Any carpenter can mount the mural. Any electrician can follow the simple instructions for installing the black light.

Figure 1 illustrates a mural of this new type. The subject is a group of rosy-red flamingoes standing in a limpid pool of water under the overhanging branches of a tree festooned with Spanish Moss. The painting is rendered on a specially processed fluorescent fabric so

that the entire background has a rich deep blue glow.

Another of the prefabricated murals is illustrated in Figure 2. Here a Mississippi stern-Wheeler is pulling away from the levee and spilling a flood of golden light over the surface of the river. The lights of a small town twinkle on the far shore. The effect is so realistic that the river in the foreground seems literally to shimmer in the radie ance from the boat. The fluorescent fabric provides a perfect midnight blue for the sky which is liberally sprinkled with light-filled stars.

Still another subject is presented in Figure 3. Bright-hued tropical fish swim above glowing beds of coral and marine plants. The fluorescent fabric furnishes an extraordinary illusion of depth.

The exhibitor who desires fluorescent murals has only to order duplicates of any of these pictures. They will be faithfully copied by the artist with exactly as much care and precision as went into the creation of the originals. The exhibitor will know exactly how his pic

tures are going to look, how much they will cost, and when they will be ready for installation. He will be spared the equally burdensome task of determining lighting requirements and of selecting the proper black-light equipment.

The standard width of the new type of mural is 9 feet and the standard height is 14 feet. The height may be modified, if necessary, without affecting the design, but the width is fixed at 9 feet.

These dimensions are dictated by the requirements of maximum fluorescence at the level of visible illumination usually found in the motion picture theatre. Each 9 by 14 mural is accompanied by a ZED-watt black-light spot equipped with a modified parabolic reflector, engineered specifically to concentrate the largest possible amount of ultraviolet on an area 9 by 14 feet. The equipment includes an adjuster, designed to fit between standard 16-inch centered joists for recessed ceiling mounting. This enables the black light to be set at the correct angle for directing its invisible radiations at the proper point, one-third the distance from the bottom to the top of the mural. The adjuster further permits the black light to be serviced either from below or from above.

Interior Decoration For All Theatres

Here, then, is a compact, packaged combination which makes black-light decorations practical for motion picture theatres of every size and type, wherever they may be located. The subjects for the murals have been selected with the conviction that the average movie goer prefers to look at aa pretty picturel' rather than to puzzle over a stylized abstraction. The colors used in the paintings are warm and true, in keeping with the purpose of a place of amusement.

Prefabricated murals offer an obvious answer to the problem of completely changing the appearance of an existing theatre without extensive and costly ree modeling. They will fit equally well into plans for new construction.
