People buy them direct from China. It's the best deal and you can custom order the spectrum, get the latest shit. Kinda a bitch but it's worth it. Otherwise buy a used one on craigslist.
Tons of fuckers grow budz then bitch out. Tons of LED's out their that work just fine and will for a long time. As long as they aren't first generation, they work well. Even so if it's first gen, just use it for veg and buy it on the cheap.
Knowledge is power, research the shit before you buy it. Any used 3 or 4 band is good enough dude. I had some cutting edge shit for a minute, 3W led's and shit but I'll reinvest soon.
I might even deal with these fuckers myself and start a small business for cutting edge LED's. Once you know the knowledge, it isn't that hard to know what to get. eBay is lame. Don't use them man. They rip you off for not having the knowledge to start your own business or cut out the middle man. Running a business on eBay is weak sauce.

Here is plenty of them to buy. Almost all the distrubters here on eBay order them from china in bulk. I bought ones from different suppliers and they all sorta worked the same. Here I search for 3W led's.
I looked at the cheapest one from http://myworld.ebay.com/ledstores/?_trksid=p4340.l2559 and it looks legit. Unless you find one used, or start your own business from China, that is the best LED light you are going to get for your money today.
Hard to invest, since every 6 months they make something better. But mostly they have stuck with 3W led's and 4+ bands as the cutting edge of LED Grow Lights on the market. Bridgelux are the cheapest LED's and CREE are the best. I used a combo one just like the one this guy is selling and it was amazing for either flowering alone, veg alone or in combo with HPS in flowering was super awesome!
The prices now are even cheaper then they were 6 months ago. It will get cheaper in another 6 months but damn those 4+ Spectrum LED lights have UVB LED's which kill mold and are awesome for plants. Those LED's alone are worth it in any flowering room, period.
The simple and very cheap led's that are only 2 band can work for veg, Red and Blue but you might as well go for a 4 or + more band unit. I had a 120W unit from eBay that had 1 watt led's and it seemed to do pretty good in a 2x5 area, even though 2 of them would have been better. The 120W unit is almost as powerful as a 400W MH for veg. I'd say plants respond better to a 120W LED 4 Band Unit vs. a 400W MH.
For flowering I never got to try just LED's, I used a mix of HPS and LED. The unit I had was crazy futurist, but cost a premium at the time. Had at least 8 spectrums. Right now is half the cost of 6 months ago. By 2012 I think LED's might just be cheaper then HPS or MH for even 1 bulb cycle. I mean right now it's about $1 a W.
Only thing about LED's is they are slightly tricky. Make sure you ask the supplier what the W draw and output total is of the unit. Once some crappy company said it was a 600W LED unit, when the draw was only 300W and output was only 300W. Regardless the actual number, I find the real world output in comparison to MH and HPS is roughy 2.5 X W of the LED Output. If you get that much LED instead of HPS or MH I'm positive it will walk all over them if you plants are trees.

Whoops. Thanks for the clarification between IR and UV, and the etc about the HPS and MH having bits of them. I guess between the group of us, it helped out a lot.
