That may work ok for a refugium, but you need some high output LEDs for reef. I also don't think those have the right kelvin temp for coral growth. To tell you the truth, lighting is what makes the initial reef setup a bit expensive. I'll post a few links for you to take a look at.

Here is my take on LED Reef Lighting.

Pros: Little to no heat transfer to the water = no chiller needed
Less total heat output into room = save on room AC
Has the shimmer of Halide lighting
No yearly bulb replacement = a big savings over time
Can support softies, LPS, SPS and Clams

Cons: Very High Cost on the front end
Expensive
Makes your wallet thinner

I have thought of doing a DIY LED setup later, but we'll see. I am weighing the costs of bulbs over time and looking for a good deal on parts.

lol my wife says im starting to act like bill nye the science guy

There are some that put lots of science and technology into this hobby. I guess I would be considered more of a lazy reef keeper. I prefer to keep things low maintenance which requires less equipment and maybe even a little less science.

well im the same way but she thinks that cause i check water all the time

I bet you are talking about this light: http://cgi.ebay.com/225-LED-Mix-Red...974?pt=LH_DefaultDomain_0&hash=item19c008d61e

The same seller has one with one with a broader spectrum that would probably make a good refugium led light for low cost here: http://cgi.ebay.com/225-LED-Quad-Ba...827?pt=LH_DefaultDomain_0&hash=item2eb072b7f3

But they also have reef lighting that you can look into. You'll notice that reef lighting LEDs generally are 1 watt each or more. This one has 50 1 watt LEDs. http://cgi.ebay.com/Aquarium-Coral-...918?pt=LH_DefaultDomain_0&hash=item19c008c646

And this one has 119 - 1 watt LEDs: http://cgi.ebay.com/Aquarium-Coral-...378?pt=LH_DefaultDomain_0&hash=item19c008c042

I've had those lights to play around with... Peronally unless your fuge is very small/shallow I wouldn't bother. You would be better off w/ a CFL and a decent reflector IMO.

The all blue ones were not even moon lights on a 30" tank.

Thanks for the input. I was wondering about those very low power LEDs. I guess they are cheap for a reason. I am sure the 1 watt setups would put out a good par rating, but I am not sure about the build quality as I have never seen them personally.

keep in mind those are not even 1w LEDs... its 13w total so each light is getting like .05w

The last two I posted used 1 watt LEDs. As you said, the first two in my post aren't really worth purchasing.
