Bridgelux or Cree?

[Stones]

+1 for Crees.

I've used both Crees as well as built a fixture soley from aquastyle LEDs and parts. I had to use almost twice as many bridgelux LEDs run at 700 mA to get approximately the same coverage/intensity as Crees ran at ~1000 mA so in the end, the cost works out to be about the same when you take into consideration the LEDs, optics and drivers. Plus shipping from aquastyle is MUCH more expensive than shipping from Rapidled or LEDgroupbuy.

I figured less LEDs on the heatsink spread a bit further apart is better for heat dissipation as well so you can get away with running a smaller fan or in some cases, no fan at all on your heatsinks. Less LEDS also means less power consumption but the savings here would be miniscule as well.
