  • Fire Rated Downlight
    Work well under fire rated downlights at 45°C.
  • U-DIM
    Compatible with the widest range of existing dimmers, whether they are leading-edge or trailing edge dimmers, with enhanced dimming range of 100% down to 5%.
  • Dim-to-Warm
    Following exactly the dimming curve of familiar incandescent and halogen lamps, the LED lamps could simultaneously emit a warmer light when they are dimmed from 100% to 5%.
