I figured I’d give the ol’ gasoline de-dome a try on this light. Let’s just say I’m 0-1. I believe it has an xr-e that I would like to swap with an xp-e on copper. Is this even possible? Will I need to swap the reflector as well due to the larger hole for the xr-e? Maybe an xm-l emitter would be a better choice? What are my options here? I know I can replace the entire light, but then I wouldn’t be satisfying my need to modify everything.

Thanks,
Steve

It should be no problem. Us one of these Centering discs

Or else you can use on XML centering disc by epoxying it onto the MCPCB evenly around the XP-E.

I’ve heard of several people who replace a similar emitter in an A60 with an XP-E2 with incredible results. I haven’t yet, but I’m planning to.

Those centering discs look like they’re the ticket. Might as well order two of the xp-e2’s because I’ve got an A60 en route, hopefully. :slight_smile: Then again, I might decide to leave it alone. Ha!

Thanks,

I believe the XP-E has the same solder pad size as the XP-G and XP-G2
3.3mm square

And after my success with a skillet on the stove reflow (which I was VERY apprehensive about) with the 12A SRK Nanjg 32*7135 driver, I am convinced that reflowing a led can’t be any harder

As others have said, drop the entire base into a stainless steel skillet, set on the stove, use some needle nose tweezers, when you see the solder melt pick up the emitter from old base, then put the emitter on the new base paying special attention to the polarity, then get it off the heat quickly

Or the safe route, buy that one on the copper Noctigon (much better heat transfer) and use some ultra gray sensor safe RTV to stick it to the pill (much safer and you won’t run the risk of burning yourself or getting stuff too hot)

Those centering rings work well as ouchyfoot said

By the way, that is a nice little flashlight!
