Well, I think I really screwed up by waiting to place an order with Arrow. I was going to grab up 20 or so of the 2 ft Samsung strips at less than 5 each, but after a couple comments I saw on here, decided to think about the more expensive 4 ft single and double row strips that are out of stock. Went back this morning to go ahead and get the 2 footers and bam, they're now priced at almost 30 apiece. So now I'm considering looking into the Bridgelux options. Anyone have any suggestions? Would really like to hit about 40w per ft in my 2.5 x 5 space without killing the wallet, which i could've done if I hadn't had second thoughts on the 2 footers.
