Lighting Art as Applied to Theatres Discussed by Publix Specialists
IN a paper "Theatre Lighting — Its Tragedies. Its Virtues," presented before the recent Annual Convention of the Illuminating Engineering Society at Philadelphia, Frank Cambria, Director of Art and Stagecraft, and Francis M. Falge, Lighting specialist, of Publix Theatres Corporation, set forth the following as the most important considerations in the lighting of theatre interiors :
i. There should be a well-planned, single-circuit system of illumination for lobies, foyers, rest rooms, etc., which
should be graduated in intensity from street to auditorium.
a. Lobies should be bright and cheerful.
1). Many small bright sources of light are pleasing for lobbies.
c. Foyers should be of lower intensity with soft colored lights.
d. Rest rooms should be colorfully and comfortably lighted.
2. There should be a specially planned and controlled system of auditorium lighting so that the advantages of mobile color

Features
Synchronous Motor Drive (110 or 220 volts, 50 or 60 cycles). Prevents variation in
speed from variation in line voltage, or projection load. The Super Cells used require only two stages in head amplifier, hence less distortion. Ease of Threading. When running disk or silent, the Sound-on-Film unit is not threaded.
Sound-on-Film threads as easily as through a Powers gate. Turn Table Is Accessible, being up high at the side of the machine.
Easy to Install. Installation can be made by the ordinary operator, and wire man. Projector Head is driven by its main drive gear and is not required to drive any part
of the sound equipment. Only Three Shafts: (1) Motor Drive Shaft, (2) Sound Film Shaft, (3) Disk Table
Shaft. Variable Speed ran be used for making schedule by driving the head off the Powers
Motor, when running silent. Change from synchronous drive to variable speed
drive requires about ten seconds. No Universals — No flexible couplings, flexible shafts, or long unsupported shafts are
used, as the^e produce tremolo. Fire Hazard Is Decreased by use of this equipment. Failure of take-up does not cause
film to pile up in light.

and variety of effects may be available together with a comfortable, glareless system for the showing of pictures.
a. There should be no bright light sources near the line of the vision of the picture.
b. Stray light should be eliminated from the picture sheet as much as possible.
c. Sufficient light should be provided so people may easily locate seats, and to eliminate accidents.
d. Sufficient light should be provided so as to discourage undue familiarity but at the same time not so much that patrons are distracted by the movements of others.
e. Aisle light and side-wall brackets should be on separate circuits controlled from the stage switchboard.
i. Cove circuits should be carefully planned so that many variations of quantity and quality of light may be possible. They should be oji dimmers.
3. There should be a carefully devised emergency lighting system, separate and distinct from the other lighting arrangements.
a. Local, state, and federal codes must be strictly adhered to.
4. There should be a separate lighting system for cleaning, preferably a permanent one, but at least portable lights and conveniently located outlets.
a. ft is preferable to have concealed units of high intensity which are operated by a switch.
b. This should include supplementary lighting for passageways and other places which might be included with other circuits not needed for cleaning.
