A small 20W LED flood light aimed at reef tanks, built as a metal halide replacement in a 20000K white spectrum. It uses a single Epistar 20W module behind a 120-degree beam, so light comes from one point and gives the shimmer halide users miss. It suits nano and small tanks or supplemental lighting on larger ones; it is not a full multi-channel reef fixture with dimming or blue control like the popular programmable LEDs. The aluminum housing is light and runs cooler than halide, which cuts heat and evaporation.

Buyers on the maker's page report strong coral growth and color under this light and like the shimmer and low heat compared with metal halide.
This is a 20W LED flood light made as a replacement for metal halide lighting over reef tanks. It uses a single Epistar 20W LED module with a 20000K white color temperature and a 120 degree beam. The light supports SPS, LPS and soft corals and suits tanks of any size.
Because all the light comes from a single point, it produces the shimmer in the water that metal halides give. It produces much less heat, evaporation and electricity use than metal halide. The housing is extruded aluminum.
