the RGB is as bright as any 3W single but here is the draw back. IT'S A BATTERY HOG. you need to own stock in duracell to keep it fed cause if look at the pic in the post it's 3 3W LED in one emitter housing. RGB is the latest technology in led. all colors can be made not just the four i show. In my latest test I have made Mace purple
LadySith Pink and a few more. With all three on and a potentiometer hooked up you can blend at will. Look at the signs in the lumileds led presentation on their site. The signs that show pictures and movement are done with RGB technology just like a projection TV. LIke I said they need power. I have alot of sabers and all my MR have rarly needed batteries or my single luxeons are not bad but this one has gotten 3 sets since i posted pics the day it was built. Just like they say "every rose has a thorn."
