+1, I am having great luck with them, better luck than the Cree's, the Chinese one's are brighter and cheaper and as long as you get the correct spectrum ones they are great, and a great buy, I highly recommend the ones on eBay, if you need help choosing the correct ones on eBay I am always here, hit me with a PM when you are ready and I will send you links to good buys and good LEDs.
