Found these http://www.amazon.com/gp/aw/d/B00C05ZJ0O. They look good and nice price. Any thoughts if this is just overkill for a tank this size? Light are able to dim.
Whats your opinion on those lights? I want to get some LEDs for my reef tank but don't want to drop big bucks. How's the light penetration? What about the full color spectrum version?
They work great, and you don't need the multicolored units. I would suggest looking at both side by side and deciding what you like the color of better. The multicolors are only for aesthetics. I have both over my system and both color up and grow corals at the same pace.
You can keep sps on the sand bed 30" away with these if you wish.
You won't see the adverse effects for a few days to a week, but what corals are we talking about? Bleaching, shrinking, melting...
You won't see it at all if you turn it way down and ramp it up over a period of weeks.
You don't even need very intense light for those, so take it easy with it. Just a FYI, just because the LED unit may seem dim to the naked eye turned down, it's no indication of how well it's penetrating. I keep corals that thrive in a similar light intensity as your corals at 100% blue and zero white. They do very well. Even a green bubble tip anemone.
Just a hook in the ceiling and and metal cable. Seems to hold really well. Would look better I think with some kind of mount but this is fine. Just need to put some sort of blocker over the front of the light so i dont have to stare in the light so much.
