I can't tell you more than what's on his site. I searched about it a while ago and stumbled on a lighting forum (he posted here too, in the shameless promo forum). I have no reason to think he's talking thru his hat, just saying that high-power LED do exist but they lose all advantages normally attributed to LED. In my opinion, putting 300$ on a high-power LED doesn't make any less sense than 300$ on HID. I don't have 300$ to burn on any kind of light, nor do I need 22w LED.
