LIGHTING WITH INCANDESCENT LAMPS 25'J Fig. 5. A schematic representation of a modeling lighting unit employing a mirrored glass parabolic reflector. "spot" them with a beam projector to give them a lighted appearance. The result is seldom satisfactory. By the use of either the 200 or 500 watt tubular bulb projector lamps, which are approximately the same size as the lower wattage lamps normally used, sufficient brightness is obtained to give them a lighted appearance. Both the small 10-watt S-ll bulb lamps in a variety of colors, and the larger sign lamps, have been employed in large and miniature signs. The extremely small flashlight lamps simulate fireflies. Bare 1000-watt lamps shining through muslin give an appearance and twinkle of stars. MAZDA lamps can be operated under water, provided, of course, they are turned on and off while in the water to prevent sudden chilling of the bulb, and if the water is agitated, the ripples become luminous. The electrical connections should be waterproofed.
