Thanks Tom! And kudos on RampingIOS, I like this headlamp 10x now. I really would like some different emitters, but my only spare XM-L2’s are cool white. I’m kinda waiting to see if anyone gets the 4000K or 5000K SST-40’s in. Those are about the only other 3V 5050 LEDs I can think of unless (outside of those crazy 3V 50.2’s). But I really don’t want to dump a bunch of money in a cheap headlamp.
- Unscrew the end cap with the 2 notches CCW. It’s probably just tight. Mine had no hint of glue anywhere. There is an o-ring though that might be contributing to the resistance.
- Desolder the LED wires
- Using a wooden stick or something, push on the PCBs from the battery tube area
BTW, I’ve seen tear-downs of the single emitter version too. Same/similar driver. But the LED was mounted on our typical 20mm star, makings emitter swaps simple… and optics and option (link). The simplicity of this driver kinda bugs me, though. It’s just a few current limiting resistors being PWM’ed.
