I have a huntlight FT-01XSE with original 3W led that has been kind of hinky since it was new. In fact my friend gave it to me years ago because it never quite worked right. Today I finally took it apart and solved the problem, which was that the piece that holds the reflector and LED module into the front bezel was just a hair too long, or perhaps the reflector was a hair short. I put the part in my lathe and turned a hair off of the front end that stops against the bezel. I probably should have measured before and after, but I forgot to do that. Anyway, the light now works like a champ and doesn't randomly turn off. My previous solution was a bit of aluminum foil to take up the extra space, but that was less than ideal. If anyone else is having problems with this light like this, it is an easy solution (if you have a lathe or a friend with a lathe). I'm surprised my friend didn't fix this himself, since he is the one who taught me how to run a lathe in the first place, and was very much into flashlight tinkering...
anyway, now all cleaned, and lubed up, it is a nice little light. If anyone can point me to any good upgrades I can do with this light, I'd appreciate that. the original LED (I think luxeon?) has decent throw, but is a little greenish for my taste. I'd also like to be able to dim the light, but I imagine that's not an easily added function. Might just leave as is, and look for another light that has that function and better LED in one? Also tempted to fit this with some kind of ~6V rechargable circuit and use it attached to generator on my bicycle, since it is plenty bright for riding in town. No need for changing brightness in that case. If there is a way to put a brighter, more efficient LED on the existing board (or some other way), please let me know!
