Both of these product families are unique in the entertainment lighting business. Each allows dimming of non-dimmable lights. We offer 2 styles, a shutter, and an iris. Each has it's own strengths for varying applications. Of course, they have feedback built in.

The shutter kind of looks like a venetian blind. The basic benefit is that it is very fast to open and close. This allows some strobe effects not commonly seen on non-dimmable lights. Learn more here.

The iris is a licensed use of a design by George Izenour done in the early 50's. It's primary benefit is 100% efficiency when open. Also the field of the light is very smooth at all levels of dimming. See a quick video here.
