The Ballastar T8 Light Level Switching Ballast from Universal Lighting Technologies allows users to switch light levels from 100% to 50%, or 100% to 60% to 30%, using standard wall switches and relays. The application benefits from uniform step dimming, with no dark spots and shadows in the light fixture or the illuminated space.
