1000 lumens at 3 amps requires better cooling than most lights have. You can still get 1000 lumens with more current though. A lot more current.

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.
