That's impressive. The heat savings seems to be huge!
They are understandably stingy with their description on their site. The led
's , or as close as I can find, are not cheap either. I guess this explains the crazy cost for these things. I'm sure you will save money on power and heat control, but you are spending most of that up front on the fixture.
It's a great idea, I'm curious about how much the High Light Output LEDs can be bought for... Hmmm.
