Definitely one of the coolest LED setups I've seen yet.

Will you use any reflectors or just use the 120 degree beam angle they come with?

A few reasons, even though the Cree's are usually more efficient than the Bridgelux.

For simplicity sake, using 6 LEDs makes life much easier on the setup.

Also, he chose some NICE LED's--- those big Bridgelux will probably have superior color rendering to the Cree's.

I know the 10-watt Bridgelux 402's gave some very nice, balanced spectral curves on the radiometer this weekend. We're compiling the data now on what all we tested.
