I have two flashlights that are both very solid designs but both with a

In each case the manufacturer basically told me they are non

Considering that there weren't cheap and are both only a few months old

As I'm not familiar with Cree LED's are am looking for some input to

Evert.


Probably not made to be easily disassembable. But can you get some
current limited test supply to the LED/s to at least confirm which one
is buggered/problem in switch or elsewhere?
Beware the LEDs are going to be closely coupled to heatsinking and the
orientations can be all over the place

I bought a cheap one at Walgreens, failed after less than an hours use.
Removed the front lens cap and saw the soldered connection to the LED
chip had come loose.

Thirty seconds with a soldering iron fixed it.

Apparently so much current went to the chip it self unsoldered a
marginally soldered connection.

Been fine ever since.
