A small 20W LED flood light built as a metal halide replacement for reef tanks, using a single Epistar module at a 20000K white color temperature. Because all the light comes from one point, it produces the shimmer that most multi-diode LED fixtures lose. It suits nano and small-to-mid tanks and frag setups where a single pendant is enough, and it runs far cooler and with less evaporation than the halide it replaces. Against spread-style reef LEDs it is simpler and dimmer, with no dimming, timer or spectrum control.

Buyers on the maker's page report strong coral growth and color under this light and single it out for halide-like shimmer.
This is a 20W LED flood light designed as a replacement for metal halide fixtures over reef aquariums. It produces 20000K white light using custom color-temperature LED technology and has a 120 degree beam. It is intended for tanks of any size and supports SPS, LPS and soft corals.
The light uses a single 20W Epistar LED module in an extruded aluminum housing. Because all the light comes from a single point, it creates the shimmer in the water that metal halide lighting gives. It produces less heat, evaporation and electricity use than metal halide.
