LED light tube for marine aquarium

[ernest013183]

Hi, I would like to know if I build my own lighting and if I use 2 or 3 18W LED light tube (Luminous Flux: 1800m) is that enough for my 15Gal Aquarium with few hard corals? :hmm3:

Which ones? It might be bright enough but not likely the right color to look good over your tank.

if you are getting actinic as well then go with 2 blue one white and you will have great look in the tank, The light might not be able to give punch deep under water since those does not have optics and they use SMD's
