BLF GT (preliminary) modding thread

I got them from Lumintop T/A.

Personally , i would try to use a fet driver and limit the current though the led wires first .

Cheap solution , but it could work to at least get the emitter at a safe operating current .

Be very careful when trying to open it up, damaged the HALIII ?? anodizing while breaking two straps, the strapping was the only thing that touched the light, the bad news is it is still stuck, they hired King Kong to put this one together :rage:

Pass the 10lb hammer will you :weary:

Cheers David

Yeah, they can be pretty tough to get open - I struggled with another one this evening, fortunately it came out un-scathed!

My replacement light meter arrived a few days ago (Dr. Meter LX1330B), so I took a couple of quick readings after an emitter swap to a 5700k XHP35 HI D4 bin.

Taken from 20 meters, the new meter reads more in-line with what I expected; 2198 meters throw, as opposed to the old meter, which was reading low, @ 1841 meters.

oh that’s a bummer pommie :frowning:

mine is still stuck and trying to find a way to open without damaging :open_mouth:

:question:

No, not at this time. People that don’t have the light already complain about this tube being too long.

And a longer tube would be excessive I have to agree, adding even more weight to the light.

Still waiting for the host…

I have actually carried the light on trails on a sling, but noticed it would have been more comfortable if it was longer, so as to rest it on the shoulder while aiming the light.
I guess I can always make an extension just for support. Thanks.

That is a point and something to consider down the road but there are a lot of things that need to happen before that.

Anyone think about changing the color of the switch LEDs? I think one of mine isn’t working properly and would like to fix it but while i’m in there maybe I could change the color?

Changing the switch LED’s is fairly simple, They are either 0805 or 0603 SMD LED’s and you can use any color you want.

I’m sure it must have been answered somewhere but i can’t find it, is the button cap retaining ring pressed in or threaded ?

Thanks :beer:

Threaded.

Thanks TA, that’s good news.

I have opened my flashlight by 2 people (my son and I) using non-skid rubber gloves.

With the stock Led obtained 925.000Cd. I have replaced it with a boiling thinner dedomed XHP35 HD and now I achieve 1.186.000Cd.

The Led I used was removed from a Haikelite MT02.

The measurements are at 10 meters. At 15 meters I get 1.118.000Cd

Nice! :+1:

Will you do any engraving or modification to the anodization?

I recently saw your Utorch… :heart_eyes:

I am waiting for a single carrier “shorty” tube. I carry the GT right at the switch area so balance is not a problem. A little less weight and smaller overall size would be nice in my opinion.

How many lumens does the light produce?

No integrating sphere. I’m sorry.

Visibly more lumens than stock.
