Also maybe interested. Was thinking of going LED somewhere in the future and was about to start doing some real research. Terrible at DIY/lack of tools, so figure top brand way to go? Idiot question though, these seem to come in one size? Do you just have to get multiple for longer tanks? For example my 55g is 48 long I believe and 18 or 24 deep. Are these actually too hoss strong and going to nuke my corals in that kind of tank?
And can't edit, but on their graphs only seems to go up to like 700 in spectrum, does that mean you still need like normal 10,000k bulbs? As you can see I know like nothing about lighting, just that my Current 6bulb T5's been fine with what I have.
