M e » I n t A e l c Acousti PERMANENT ITelotex Lighting Needs a Thorough Spring Renovation, Too (Continued from page 63) luminous sources are turned out entirely. The result can only be groping, inconvenience, and discomfort for patrons, as well as inefficient but expensive lighting. There are many things that can be done to produce good auditorium lighting. Inasmuch as values of brightness are the principal causes of difficulty, the efficiency may be improved and the cost reduced by using 6 or 10 watts of lighter colors such as green, amber, or rose, rather than 50 watts or more of highly absorbing blue. Further advantages in efficiency as well as in distribution of the light can be obtained by using reflectoradapters. A rose color, possibly with highlights of green or blue may be a better choice than amber for summer. In any color scheme, highlights of another color serve as accents and relieve monotony. More light is needed at the rear of the auditorium. Fortunately, illumination near the rear of the auditorium is less annoying than that nearer the front. Select the location where light is spread over the largest area near the rear of the auditorium, and build up the wattage in the lighter colors there. Supplement the present lighting by some such method as the following: 1. Lamps, especially of the fluorescent type or filament lamps in reflectors, on the forward side of the ceiling beams as far down as possible yet shielded so that light is cut off at the vertical. 2. Side wall indirect luminaires, either incandescent or fluorescent, with mirrored backs projecting a foot or so above the lamps to reflect light to the ceiling and prevent high brightness adjacent to the lamp. 3. Place indirect luminaires (such as No. 2) or shielded floodlights (such as the reflector or projector lamps) at the rear of the auditorium and near back wall or on pedestals at the standee rail to direct light to ceiling and back wall. That “just as good” argument often used to sell second-rate material is always to be taken with several grains of salt. Beware of substitutes when they’re said to be just as good. Before you air condition your theatre be sure that you know your requirements and remember that good equipment is not everything. The way it’s installed is more important. PLUS S'ntjMtee'UtUf TO give every seat in your house, the full benefit of Comfort Cooling, your air conditioning installation must be engineered to fit your house.
