A better reflector and lens for the UF 2100

I found a better reflector than the aluminum stock and Ledil Regina reflectors for my E1320 custom UF 2100 at FastTech and want to share my findings since a lot of members have this particular light.

I moded the light from the stock XML to XP-G2 R5 led in 2B tint while keeping the E1320 driver at 3A, it puts out as much light as the XML but in a smaller, brighter spot.

The Ledil Regina smooth reflector further concentrated the XP-G2 spot but it was a pain in the butt to center since you have to remove the plastic tabs to have the reflector sit flush with the base of the led, and usually it moves when the pill is tightened.

Found by chance this smooth aluminum reflector at FastTech that has a metal lip on the reflector hole that properly centers and focuses the XP-G2 led and gives a very good narrow spot with a nice corona.

The size of the beam is exactly the same as the Fenix TK22, here are comparison beamshots

Pretty cool mod, thanks for sharing.

It's always good to have real-world feedback on these DIY parts.
