I've been buying my LEDs from
www.autolumination.com for years. Chris Bacon is the owner and has excellent and fast shipping. Communication is great also. I've eye'd the LED boards that he has listed on the site now. I had actually thought about doing this a few months ago. I just haven't had the time to devote to it. Check out Chris's site and see if there is something that you can use. His prices are very affordable.
