Soo... I grabbed a couple cheap P60 drop-in LED's off Amazon for my Surefire 6p Defender that I recently bored out to fit 1x 18650, and the first one died after about 3 minutes of use. Being the curious sort, I decided to take it apart to see if it was the driver or LED that crapped out, and when I flipped the driver PCB... this was what I saw.
Not one single resistor, coil, buck driver, etc. Guess that explains why it popped so fast.
