Need help with some technicalities

I’m trying to build a thrower drop in to go in my MT-G2 Maglite HERE for reference, but I have only further confused myself with LEDs.

I was originally going to use an XP-G2, but then I reconsidered, and thought abut using an XR-E.

My question is as follows:
Would the XR-E out throw the XP-G2 in the same size reflector if they are both driven to their recommended max current? Or would the XP-G2 be able to reach further just with pure grunt?
Also how drastic an effect would dedoming have on both ?

Help with finding a reflector with a better beam pattern than the Mag rebel reflector would also be appreciated.

If it was me, I'd go with a dedomed XP-G2 or dedomed XM-L2 in a light like that. My experience has been that a dedomed XP-G2 can throw almost just as far as a dedomed XP-E2 or XR-E, but the hotspot is bigger and much more usable. The only reason I'd use an XP-E2/XR-E over a dedomed XP-G2 was if I was trying to limit my current draw, but in the Maglite that won't be an issue.

I can't be of much help with the Mag reflectors.

Thanks for the help !
