FCL4 4" Dimmable Retrofit LED Downlights

Product Description

The 4 inch dimmable retrofit frosted LED downlights adopt high brightness Cree, Nichia or Epistar LEDs as light source. Aircraft grade aluminum alloy housing and patented frosted optics lens ensure ultra efficient heat dissipation and uniform light output. With a power consumption of only 12 watts, the FCL4 LED downlights can deliver up to 1,000 lumens. Compared with conventional downlights, they can save 50%-70% electricity with the beautiful light quality that you would expect from an incandescent. The LED downlights fit into most popular 4" recessed can housings, and they are also available with a dedicated rough-in section for new construction.
