The most approved method of stationary electric lights for windows are those placed at the top, next to the window pane, and so arranged as to throw their light downward and backward from the observer. Thus the entire window space is fully illuminated and the incandescents are themselves hidden from view. Separate reflectors or a long reflecting trough of tin should be placed back of the lights. Special lighting effects are explained in detail further on, but the regular lighting is best arranged as above.
COLORING ELECTRIC LAMPS.
Where colored effects are desired the incandescent lamp globes may be tinted to throw distinct or combined colorings over the entire display.
There are several preparations that answer the purpose, and indeed are best at times. Pikron for glass is excellent, or a lacquer will answer. However, they sometimes become spotted from the heat.
Another and better method is by using white shellac, thinned down with wood alcohol, and by dipping the globe this produces a splendid imitation of ground glass when a white light is needed.
If you wish to use purple, green, blue, etc., or any of the more delicate tints, such as violet, buy five cents’ worth of aniline dye of the color you wish; dissolve it in wood alcohol and pour it into the shellac, taking care the shellac is quite thin, as otherwise it will not cover evenly.
DESIGN SHOWING PANORAMIC EFFECTS.—Sawyer.
By using these or any other transparent coloring a vast number of beautiful tints can be made that will blend perfectly with your color scheme. Another excellent coloring is egg dye, treated in the same way.
Now I will explain how to go about it. After preparing your shellac pour it into a vessel deep enough to immerse your lamp.
