Steve
incorrect sir

They run them at 70% to keep heat down and extend the life, that is the general consensus of output with extended longevity using standard hobby cooling.



I don't know what else to say other than try posting that light on any reputable board that has people who know about LEDs and you will get your answer very quickly. 1w LEDs just do not cut it. That is what im trying to get across, most of the cheap LEDs fixtures that come from china use sub par 1w LEDs (not all of them but MOST of them).

Also, if anyone has that fixture, we can put it up against 1/3 or 1/4 number of CREE LEDs and see the difference with a par meter and just your eyes.
