With the same current, you can get many more lumens by mounting the LED directly to copper. About 300 lumens in this case, with even more at higher current.

These results has me wanting to buy a lathe.

Thanks for that info. Didn't someone over at CPF had something like custom made copper bonding for the LED instead of star which he uses for his custom flashlight? If so, I wonder does he sell them. It would be fun to play around with using drivers that are 3amps and higher.
