Mainly wondering if I would be able to take the stock Cool White XM-L and replace it with a NW-WW XM-L. I don't know if it uses a standard sized star or not, that really should be the only thing limiting the chances of replacement right?
Yes the emitter is fairly easy to change. Freeze the pill first and then carefully pry the emitter off with a screwdriver, remove the wires, clean the adhesive off of the pill, apply some new adhesive (I use Fujik), press the star on and solder the wires back on. You need a 16mm star to replace it with.

So, I got the 16mm star over the weekend, but the P-Rocket definitely takes a normal 20mm star, ordered one of those from INTL-Outdoor and will mod once it arrives.
I had a camo one I modded for someone it had a 16mm emitter. I put undersized emitters in lights all the time. Just use spacers and be careful and you can line up the 16mm to fit perfect.
Yea, I think the UF-T50 I got today uses a 16mm star though and I plan on using the one I got for the P-Rocket in the UF-T50.
