Using a 575W HMI lamp, the Seachanger HMI produces 24,000 lumens for a luminous efficacy of 41 lumens per watt. Matching the patented CMY color process with an HMI lamp yields high light levels with nearly endless palettes of stable, reproducible colors that do not shift or fade with time or temperature. The fixture includes a mechanical dimming wheel for controlled dimming, as well as ETC Source Four Ellipsoidal components, making it compatible with all standard accessories. It is available in Profile, Wash, and Outdoor models. Also new is the UltraFast Color Transition technology in all Seachanger products for ½-second color changes.
