Title of page: Colortran

Colortran Industries started in the early 1960s by Ben Berkey of Berkey Photo with the Colortran Converter product line. It consisted of a multi-tapped switched transformer or transformers in a case which was operated by the grip or photographer to increase the output voltage to location lighting head(s) or luminaire(s). Increasing the voltage to the lamps then proportionally increased the light output and color temperature briefly on location production shoots to "get the shot". "Colortran" was short for Color Transformer. As Colortran Industries was a division of Berkey Photo, a few years later it was renamed Berkey Colortran and intense luminare development efforts resulted in the then revolutionary Colorspot, a line of cyclorama lights, location photographic lights, a line of fresnel fixtures, and the elipsoidal reflector spotlight which using an aluminium polished pop reflector, a FEL lamp, and advanced optics nearly doubled the light output of elipsoidals of that era.
