Just dropped the hammer on this one, bought one of those USB chargedoctor things to kick it over $25 for free shipping…let’s hope it comes with a heatsink!
Pop out the reflector and tell us what you find. How are the LEDs mounted? Are they on an aluminum shelf, or a plate that at least touches the insides of the head? Or are they on a cheesy little piece of aluminum that doesn’t conduct the heat anywhere?
I would like to acommodate your request but alas I could not. I ruined the switch when trying to take the switch assembly out :-(
Then I bent the metal rim that the switch pcb sits on by using a screwdriver to attempt to press out the driver. I also cut the insulation on one of the wires for the switch. And heard an uncanny crunchy sound when i pressed hard with the screwdriver. So it is no worky for me now :-(
From what I can peek through the switch hole it is a common led mcpcb that rests on a thin ledge inside secured by at least 2 screws.
Good news: I cannot could not detect pwm when it still worked. The reflector seems flawless. The light is not glued anywhere.
Bad news: The led insulator gaskets have high rims that catch some of the light. I did not get to measure throw or lumen output before i ruined it. But a guesstimate (eye only) would put output at about 2300 - 2500 lumens and throw in the ~30 kCd range.
I hate that I did not get it apart! And that it broke in the first place!
I was afraid that this method would cause the traces on the circuit board to delaminate, but after I exhausted other possibilities, I tried it and it worked for me
