I have seen it. They don't seem to just sell the LEDs however. I am very impressed with what they have done. Attaching the LED die directly to a piece of copper does wonders for heat removal. Although I am impressed with the 16W it will not be as good for throw as the surface brightness is reduced vs the 8W. I bought an 8W head to experiment with. I want to see how well it compares to Cree's XR-Es. I will post my findings.Have you seen the LEDs from here: www.powerledlighting.com I was curious if the 8watt far projection would work better in the DEFT. They are in the works of creating a 16 watt version.
