After some more focus tuning and final assembly, at 20 meters, my modded GT measured at 3,508,000 lux! Super!!

Not bad at all, makes me want to give it a try. With that new “flat black” that has a neutral thermal pad, it would be far easier now. Could even use the stock driver I think with a minor mod.

What driver are you using?

I’m using Lexel’s BLF GT Oslon driver set at 4.5 amp max. In the case of the GT, the neutral thermal pad is not a big advantage because the light body is not used for the return.

In person, the beam from the GT appears to go farther. It’s quite impressive.

pscal….very awesome mod! I love it! I was pretty happy with my GT until I read over your mods. Now I’m gonna end up cracking my open before long. Thanks a lot! Wink

Oh, I would love to see some beamshots of a water tower or building from some distance. Would be even better to compare with a stock GT.

Thanks! I no longer have a stock GT for comparison – best I can do is an MF04s. Getting beamshots is also challenging for me right now because I have a toddler and an infant that dominate the night hours. But, if I can get away, I’ll try to get some shots worthy of this GT.

pscal’s aspheric builds are right up there with deft-x quality, but with 3x more lux, great job Big Smile

I haven’t seen another video about how to open the GT. So I hope you find it useful.

Lucky fellow. Usually the head breaks loose before the bezel, or did you have to reef (tighten the living hell out of) the head first Big Smile

I don’t bother with the bezel anymore, just removing the head get’s me to the area I need to make changes too. Less chance of crap falling into the reflector, specially from the loctite bits from the bezel, if I need to shim the reflector on the XHP35HI GT, then I just break the bezel loose, I don’t remove it, that way I can tighten the head with out all that added pressure on the lens.

Can someone point me to a thread on changing the XHP35 HI version to the XHP70.2? Would like to know the process for my BLF GT

Have you ever changed a driver or led? That’s all you basically do.

Check VOB’s video here.
