We are one of the only remaining suppliers of parts and service for Colortran Dimming Systems. Originally LEE Colortran out of Burbank, CA, these systems still exist as workhorses in thousands of schools, churches and theatres across the US. The most common type of Colortran system is the ENR (with or without Viewpoint Architectural control). Colortran "D-192," "I Series" and "I Series e" systems were also quite popular. The ENR system was later renamed as Leviton "Topaz," but they are identical systems. Please contact us to find parts to keep your system running, to learn about our preventative maintenance program or to discuss upgrade or replacement options.
