Amazing natural shimmer you've come to expect from Kessil, with a controllable LED, now in a compact package. We can't help but be impressed with the natural looking lighting effect produced by Kessil LEDs. They produce an amazing shimmer to rival a metal halide and you can even see the shadows of fish swimming over the sand - just like in the ocean. Kessil has put years of research into their LEDs creating a Dense Matrix LED which tightly packs the LEDs onto one chip with numerous colors and numerous wavelengths of light.
