FWIW, I took mine apart to see if I could. I’m thinking I’ll order a XP-G2 model in the color I want, and swap the pills so I can get the Nichia 219 pill into a body with a better color. Not sure what I’ll do with the XP-G2 one afterward.
The pill is glued in, and difficult to remove. I had to wrap it with leather and use a large plumbing wrench to unscrew it. Be sure to remove the O-ring and lube first.
When I put it back together, I managed to fix the centering of the emitter by jamming a sliver of paperboard between the side of the plastic centering guide and the pill. No more dark crescent on one side of the beam, but there is now a barely-perceptible mach band between the edge of the hotspot and the beginning of the spill — so it’s still not quite a perfect beam.
Another difficulty I had in re-assembling it is that the lens O-ring kept wanting to squish out over the lens, which I suspect makes it far less waterproof. I didn’t find a great solution to this, but pushing it back with a plastic fast-food knife seemed to work well enough. I haven’t tested it underwater yet. I’m worried though, because this is my favorite light to use in wet places and I may have just made it unsuitable for that sort of thing.
Also, after re-assembling, it’s much much easier to unscrew the pill, so I’m a bit worried that it might loosen over time by accident. I added a bit of “Super Lube” PTFE grease to reduce the chance of water getting in, which also makes it easier to unscrew, but even without that I no longer needed the wrench to open it.
I hope Jake / SBFlashlights will offer the 219 models in more colors soon. I’d like to have one factory-intact with all glue and seals and such in a color I like. Regardless though, still planning to order a XP-G2 and swap bodies.
BTW, as a side note, don’t put much pressure on the tail lanyard hole. It doesn’t take much force to bend it. I tried to fashion a tail clip out of a paperclip, using that hole as an anchor point… and even the force of bending a paperclip through it was enough to damage it. Thin aluminum is soft.
