LED Reef Lights

Hi, I'm new to this site and I'm wondering what everyones thoughts are on led reef lights and whether or not they can sustain coral growth? I've been looking into building my own, but it's a big investment without knowing whether or not it will work, so if anyone has tried LEDs or knows anything about their ability in the reef system please let me know.

LED is the Best choice IMO because it gives off low heat and lots of light. I would say about 3 watts per gallon for LPS, zoos, leathers, mushrooms, polyps, and basically most corals. But I'd say 4 watts per gallon for SPS and Clams. I'd recommend checking the PAR on the fixture though. Anyway that's just my opinion. Hope that it helped.

Yeah it helps! I'm looking to build my own fixture though. I'm looking at using the Cree XR-E LEDs, it should be much cheaper than buying a fixture.

Do some searches for Ecoxotic panorama LEDs, I have them and love em. With LEDs, watts per gallon means nothing. If it did, none of my sps should be growing. Just do a search, I'm a true believer in them.

Yeah I've seen those reviews as well. Just keep in mind, American aquarium is the main distributor here in the US for aquaray and I've called their customer support, and if you grill the guy, he really, just repeats the aquabeam specs. I couldn't get a straight answer out of him. Also, I personally know someone how as a 75 gallon tank with aquabeam 600's, four of them, and he's not very impressed. Four is the recommended amount by American aquarium. I do know someone else who does love the aquabeam 1000 though, it's a little different of a comparison. On the other hand, I've had my Ecoxotic panoramas for around a year, and I'm very happy and impressed. Couldn't be happier. And trust me, if I wasn't, I would be the first to scream and squeal to everyone everywhere. Especially for the price. Just my experience, but I would love to hear other's experiences since LEDs are rapidly evolving.

I love DIYs. And if you are looking to build one yourself without soldering much, go to here http://www.creativelightings.com/mob...ult.aspx#C1056 they have led pucks that come in strings of 20 but they do custom jobs so you could do 30. And each one is about 2.60. I'd get 13 white and 17 blue then you can hook them up on 1 12 DC power sources for 15. So that would be a total of $93. Cheap huh? Then you can Mount them on a cheap light fixtures which aquatraders.com sells. You can get one for under 50 with shipping so there's a cheap LED fixture for under 150. And each LED puck is about 3w so that's 90w. That should be great for a 55.

I have LED Reef lights, and i love them! I have a 48" and a 36" marineland reef light on my 75Gal, and my corals due better under them, then my old 4HO T5, and 2LO T5. My marineland LED REEF lights togeather put out a total of 6,000 Lums. Better then MH's, and 6T5's. And I never have to change a buld out.

that's not true at all. A single 400 watt halide puts out 40,000 lumens, and a single high output t5 lamp puts out 5000.
here is a graph to chew on:

Not all LED fixtures can support corals, even though they say they can.
i have heard good things about the aqua illuminations SOL fixtures.
