XML star and driver set for the UF-2100?

Hey everyone:

Anyone have any suggestions for a xml emitter/star and driver set for the Ultrafire UF-2100 pocket rocket?

Stock star appears to be 14mm (but maybe pill can take up to 16mm?) and driver is 17mm. I have replaced a couple drivers, but am still new to this so I don’t know if the star is a normal size.

I missed out on the big BLF UF-2100 custom mod just in time for mine to burn out. URGGGGGHHH.

The emitter last night quickly dimmed suddenly for no reason and now stays dimmed at about a dazzling 10 lumens. Modes still work but very dim. I’ve had a couple Q5 lights crap out in this way.

Disassembled everything and tested everything: switch, etc. Tried the star with two +known-good+ (but disco-mode) drivers. Still dim. So it looks like the star and emitter bit the big one. (Unless someone knows another reason for a dim emitter — no, it’s not the connections). Driver appears to be okay, but I want to change that out also just in case it’s what crapped out the emitter in the first place.

I apologize if I’m not using the correct lingo for any of this. As I said, I’m semi-new to this driver modding, but hope not to be for long.

Thanks for any help you can give.

Get a E1320 driver and a XM-L U2 1C tint from LEDDNA and mod it yourself, not tat hard to do, the 2100 can take 16mm round MPCB

My main business is guitar wiring (and build) mods and audio cables, so I’m no stranger to soldering all manner of crazy devices and configs, although some of these driver solder points are MIGHTY small. :wink:

Is the XM-L just a “loose” xm-l, or is it attached to the so-called star?

Is there any reliable driver and xm-l emitter sets from web sites? I notice there are a TON on ebay, but of course no way to know what’s good and what’s not.

Thanks for your pointers. I really appreciate it. :slight_smile:

In my experience, the problem usually arises from a lack of a good thermal pathway. This can be from too little (or too much) thermal goop, or an ill-fitting pill with an air gap betwixt pill and body.

If you can cram in a 16mm star, go for it. The custom E1320 driver will give you an awesome moon low as well.

Happy modding !

Seriously, someone should put up a tutorial how to mod those stuffs….

Brted did an awesome job with his flashlight Wiki page.

The how to on P-60s is almost identical to doing the UF-2100 pill

I agree, but then you might miss all the great threads you find when looking around. It seems I learn more by tripping over something while looking for something else. Something to be said for both opinions.
