9x Cree XP PCB for cheap 9-LED flashlights. Although the Cree XP LEDs have a separate, electrically neutral thermal pad, it has been joined with LED- on this board, to help spread heat away from the LEDs. Most LED flashlight drivers use the LED- for current regulation. This board won’t work with those drivers, unless you find another way to isolate the LED- from Batt- in your flashlight. It is meant to be a drop-in replacement in lights which don’t include a driver.
