I am considering to buy a 50 watt LED lighting for my 75 gallon planted fw tank.
Anybody use LED for fw tank ?
How is it compared to MH in term of brightness, light penetration and color temp ?
One 50 watt LED enough for my 75 tank ?
Are you sure that's LED in the video? I don't think LED can change color. Unless it's a lamp with a few sets of different colored LED programmed to work like an RGB projector.
