BLF GT (preliminary) modding thread

That’s the Texas_Ace prototype that was sent to vestureofblood, right?

Nope - it was built by a guy on Reddit.

I wonder why he put that comic sans “G” on there? It reminds of that prototype that said Giggles.

I had not even noticed the “G”, but you are exactly right… it sure does look like ‘Giggles’. :+1:

Yeah, and VOB has a lathe. I thought he might have shortened it and cut new threads. Now that I think about it, it doesn’t really make sense for him to cut down the double length tube.

/\……. :+1:

I sent him a PM to ask about the G. This was his response:

Definitely a nod to the prototype.

The battery tube hasn’t been cut down - it’s a 3D printed part. Note that it’s missing the o-rings.

Nope, my light is still safe and sound with me, I still love the giggles engraving on it.

I did post the laser engraving file for the GT so I am guessing someone else used it to engrave their own.

Does it count if you measure the lux at 5m or should I be measuring it from farther away
Cause my GT gets 1,235,000 cd at 5m

5m is fine, usually the readings are a bit higher at 10m.

^That.

5 meter is bit short, you may be off a few percent, some people even claim that 20 meter is not enough for good collimation and thus correct measurement. And technically they are correct.

But then I claim that the error of their luxmeters is more significant than the difference of measuring between 5m and 40m.

Moreover, the focuspoint of not all GT’s is at infinity as it should be, so if you have a very unlucky GT, the best collimation could even be at 5m.

My first mod

CW-ing my GT with 6500 k

So I’ll test it tonight and if the cd drops off after 5m it’s not a good focus? I damn well hope it isn’t cause that will bother me is there any way to fix it if it’s out of focus?

And if it changes anything I switched my led to a 5700k

Raise or lower the reflector in relation to the led.

It dropping after 5m can also be a sign of humidity / dust in the air.

Thanks!

Oslon Flat Black + Lexel Driver + Optolife Lens - 1.86m lux

Wavien collar coming soon.

Very nice, I have on of those optics myself but have not had time to figure out the mounting setup, I figure I will 3D print it but just have not had time.

How did you mount yours?

4” PVC cleanout adapters (2) are what I used. They were easy to chop and sand to get good focus and retain the lens from the top.

Great job on the mod!
It’s not easy to mount aftermarket lenses :stuck_out_tongue:
