COLORTRAN'S QUARTZ LIGHTS
They’re extremely light weight, versatile, and require no converter. Utilizing the relatively new quartziodine lamp in a specially-engineered reflector, the Quartz-Kings provide a high volume of photographic illumination of excellent quality.
/^olortran, which pioneered the first effective J use of boosted-voltage illumination for photog¬ raphy and ultimately made “ColorTran” a house¬ hold word among film makers the world over, is the first major lighting equipment manufacturer to adapt the quartz-iodine lamp to full-scale motion picture set lighting.
Following extensive experiments and tests that revealed what could and could not be done with the tiny Q-I light source, ColorTran has come up with a series of lighting units that provide power
FIG. 2 — ANOTHER INNOVATION introduced with the Quartz-King "Dual" is the “intensifier" accessory, shown here. It snaps on to front of the lamp housing where it gathers up spill light and concentrates it in a more effective beam of illumination.

ful controlled photographic illumination, utilizing the maximum efficiency of the Q-I unit.
Much has been published in these pages in re¬ cent months regarding recently-introduced photo lights equipped with the quartz-iodine lamp — a product whose real potentials for cinematographers was not generally recognized until Sylvania placed its well-known Sun Gun on the market. Its impor¬ tance was further emphasized when, in April last year, the Academy of Motion Picture Arts and Sciences honored the Sylvania Sun Gun with a Class II Technical Award.
But our report here is essentially about the new ColorTran lights that utilize the quartz-iodine illu¬ mination source. What has been stated above is merely to establish the introduction in the film industry of Q-I lamps, insofar as they promised an interesting new light source for cinematography.
The first thing that ColorTran engineers discov¬ ered was that the quartz-iodine lamp required an entirely new type housing and reflector for the most effective illumination of motion picture interiors. They finally came up with a housing that not only took advantage of all the lamp’s high-intensity illu¬ mination but also effectively amplified this illumi¬ nation output as did no other lighting unit thus far designed to take Q-I lamps. ColorTran’s re¬ sulting product — the Quartz-King — found imme¬ diate acceptance among photographers who require a compact, lightweight and powerful illumination source to meet the increasing demands of on-loca
