DMX Pixel and Flashlight
Read full descriptionHide full description
Recycle your old iPhones to use them as a light source for shows. Connect them to a DMX source (thru sACN) and use the screen as a RGB pixel. You can control the flashlight intensity as well. Select the shape of the Pixel: Full screen, square, circle or sphere. Connect as many iPhones as you want. Use them to hide lights in a set, as close light source for actors or musicians, as part of a scenery for visual effects or as a mobile cue light.
