I have a digital caliper, will measure later tonight, I did not find a similar host and ended up buying the light. I love it, changed the led to XP-G2 and it throws!
Both with 17DD momentary drivers, 6 levels, the $12 one has the stock XML moved onto a Sinkpad, the UF-T50 has a XPG2. The only difference is the cheaper one doesn't have anodized threads or branding on it, other than that they're both similar build quality. Both outperform a P60 built with the same parts, there's something magic about the reflector in those little lights.
Comfychair, how did you heatsink the pill on that Ultrafire? I read somewhere that it’s a bad heat transfer design from the pill to the head.
I would probably get rid of the magnet inside the cap for more room to add a front spring and bigger heatsink.
That EagleTac reflector is available to buy on its own. That thing throws 20KLux with an XM-L2 at 3.3Amps…
Imagine that thing dedomed with 6Amps… All i would need then is a host that fits it. That would be easy. (sarcasm)
The cheaper version is actually better - it has the pill clamped tight against the bottom of the head when the bezel is screwed on, the UF-T50 isn't like that, the pill just hangs off the bottom of the reflector and floats in empty space in the head. It can be shimmed to fill in that gap and make it fit correctly, but it's easier to just buy the one that only costs $12 and put the good parts in it.
