I wasn’t able to achieve the calculated theoretical emitter current either with resister mod. Also 5+ amp. I have to go back into my light sometime. I think there must be something wrong or maybe I fried a resisters when installing them.
May I ask at what distance you measured lux? I get higher numbers at 24 feet (381kcd) than at 10 feet (347kcd). Has anyone figured out the best minimum distance to measure at.
EDIT: I just saw your post #57 at:
Thanks for that post. Very good info.
EDIT2: The two measurements above had been take a separate times. Something else must have been different, because I have been remeasuring and getting fairly consistent results at the two distances.
