Be careful buying anything off Alibaba as there are many cases of them selling fake LEDs that are not what they are advertised as. For example, quite a few guys on RIU bought LED boards that were supposed to be LM561C S6 (top) bins, but turned out to be lower quality (and cheaper) LM561B chips: http://www.rollitup.org/search/65871261 ... s&o=date&c" onclick="window.open(this.href);return false;[title_only]=1&c[node]=124
It's real easy to get ripped off if you don't know what you're looking at, as the chips can appear almost identical and you need a PAR meter to work out if they are performing the way they should.
My suggestion: by Samsung strips from Digikey or Arrow, or look into Quantum Boards or similar. RIU has loads of info on LED builds - everything you need to educate yourself and give you an idea of where you want to go.

301Bs (Q Series Samsung strips) are coming down in price. But F Series (LM561C) are still the best value. I just bought 10 more 2' strips for a couple of vegging frames I'm building for a commercial friend.
