BLUE GROWTH is our 10,000 Kelvin lamp series and – as the name indicates – is a light designed with coral growth as a priority. The lamp has a strong element of pleasing blue color, but overall it is the whitest halide light that we offer. On this warmer side of the spectrum, you will enjoy the most useful light quality for growing the widest range of corals, especially shallow water species. Coral farmers and enthusiasts of keeping shallow water coral species, anemones, and luscious ornamental plants heavily favor this lamp
