LED technology is advancing so rapidly manufacturers aren't even trying to utilize the latest high power emitters. I myself have upgraded one of my LED lights twice in the last 4 months. Building your own is the only way you'll be able to have the brightest LED light. Go ahead and build that LED light! The commercial manufacturers are years behind.
