[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

I’ll have a handle proto tomorrow. Had some water freezing issues and a 44,000psi leak to deal with Monday - Tuesday. Played catch up today.

It a 19mm diameter cob style led. $379 without the heatsink. It has a 35 to 39 volt input and does about 450 watts.

It would not be suitable for any type of thrower as the hotspot would be huge. You would probably get 500 to 600 meters from it in the GT (my rough guess).

Good lord! Makes the cft90 look like a spot of mustard on a white shirt. Thanks for the link. Teats on a boar hog.

Im dying in anticipation,
So many great reports from those who have there gt’s
Im in the next 500 i hope,
Even though i havent recieved mine yet

I would like to ask for a second if its possible

This is a standard Narsil feature, but it should have been in the manual anyway. Just added this to the FAQ in the support thread:

  • The GT has low voltage warning and shut-off. At what battery voltages does this happen?
    • At 12.0 V (3.0 V per cell) the GT will blink the main LED and step down in power. It will do this repeatedly until the battery voltage recovers above 12 V.
    • At 11.2 V (2.8 V per cell) the GT will blink rapidly and shut down the main LED.
      Note that these voltages can be ~0.05 V per cell off in either direction, depending on the component tolerances and temperature. These voltages are monitored under load and cells will read higher when removed and measured outside the light.

These numbers are from the NarsilM 1.2 source code, but I did also confirm them using a power supply on a production light.

Thanks for posting, hope the reflector complaining goes down after seeing this. Have to blow up this picture to see good.

what exif viewer is that ?

I use medical hemostats to remove button retention rings. If the ring needs more force, I use mini needle nose pliers.

I’ll complain. LOL. I don’t see any OP in my reflector. I do see turning marks, kind of, barely. Programming and equipment… which is fine for the application. I’ve been spoiled with nothing but Okuma lathes. The old LC20 (mid 1980s) could keep that profile or better. The newish LB3000 EXII with live tooling is amazing.

Does anyone know how the reflector is finished? Is it plated or electro polished? If it’s electro polishing the OP effect is the result of cooking it a little too long.

You could also get thicker neoprene foam insulation and glue it in. I’ve seen it up to 1” thick. What I saw was used for pipe insulation. I would think hard substances would just transmit any shock directly to the lens where something cushioning would prevent it from getting to the lens. Heck, a piece of the packing would do the job, but I don’t know if it could be glued in place. Loose would also work I should think.
—————————

FWIW, I don’t know if there were complaints. Maybe one, but I didn’t take it as a complaint (I didn’t see the above post). I know my comment regarding the small OP effect wasn’t a complaint; it was merely an observation.

TBC, you could sell your light if you’re unhappy with it and the price paid for it. There would be plenty of folks who missed the cutoff who would be happy to take it off of your hands. That would free you up to but the light of your choice made with the lathe of your choice.

I assumed it was physical vapor deposition (PVD) as most modern reflectors are. Maybe one of the Team members knows for sure and can clarify it.

Thanks DEL.

Is there any statistics how many people have already received their lights, I number 149 in the list of 555 and silence :weary:

Got my 2x BLF GT`s today,
Thank you very much !

:+1: …… Done & reply sent. :wink: … I concur……

Exif viewer 3.6
For mozilla

Thanks for the update TA!

There were 362 shipped from the first 2 shipnents. Those were both USA shipments.

There seems to be a lot of international lights shipping now. See post #1 for details.

I also just posted a list a names on post #15426 that shows the paid list numbers of these most recent shipments. You are #101 on that paid list and people all around you have gotten shipping notices so there is a good chance yours has shipped as well. I suggest calling DHL and asking if you have a package on the way.

The cutting tool is expensive. The flashlight is cheap. For this reason, the tool can not be changed frequently. A worn tool makes worse the surface. It’s a compromise. Just my opinion. I am also a metalworker.
