I finally got my DX 5 cree dropin but my office is closed for the weekend!!
What did you do with the busted DX 5 cree dropin? Did you replace the driver?
Have it taken apart. All 5 LEDs work. I am going to resolder the driver and see if it works. Many of the problems are due to poor solder jobs. Looks like that module is powered with a boost driver as it take 15 volts to run the LEDs.
