Couple of points:
- Test was performed exactly as all of my emitter tests - which is mounted to a 1lb piece of copper barstock imbedded in a 25lb block of aluminum.
- Heat is the key. The cooler an led can be kept, the more power it can be fed to produce more light.
- I have @ 10 150w peltier coolers at work that I could stack together to get an led close to cryogenic...but other than academic interest a test like that wouldn't have much bearing on what could be done in relation to a flashlight.
The results from that test are here. For Justin's benifit, I sent him a graph depicting all three tests.
