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

@Bozlight29

Let’s hope that the European GT’s ship this week and Lumintop doesn’t wait for the second round of $150 GT’s to combine the shipment.

Lumintop should ship Asean’s GT first after USA’s GT.
Just kiddng…

I tried a variety of methods to get the bezel off (clamp in vise, twist with hands, press down on rubber or leather, twist with hands), but I guess my hands are not strong enough. I think I’ll buy two rubber strap wrenches (like in the picture below) and twist in opposite directions. If that doesn’t work, I don’t know what will.

Maybe we could tell the factory to lower the torque settings on the head and bezel. They are tight to the point it feels glued. I know there’s no glue, but wow is it tight. There’s no need for it to be this tight.

I have a pair of gloves rated for high temps, for cooking on the BBQ, and they work amazingly well for removing jar lids. When my GT's arrive I'll try them.

If you have a pair, clean them up real good to remove any grease, dry them out good, clamp that light back in the vise, and try it.

[DENGOH]

Looks like many will open their GT to let the smoke out for first few days or weeks
I migth do that too. :person_facepalming:

[JasonWW]

My hands didn’t slip, my arms just did not have the strength to twist it. The strap wrenches extend the diameter and give more leverage. That should get it done.

@mrheosuper

We should make an account and there will be a team manage that account. In case someone has their own thing to do

@ARsee

Will someone please “list” for me, ALL “Team Members & Affiliation” involved in the BLF project.

@Texas_Ace

Yes, from now on the projects should use a Team account to handle all thread making to keep issues like this from happening again.

For now, the issue is that even if we make a new thread most will not find it or read it but the Team will have to read and keep track of both threads.

I don’t see it fixing a lot of issues at this point but it would add a lot of work.

I think KawiBoy1428 was the only one that had any smoke (on only one of his two lights). Mine didn’t. I haven’t heard anyone else say they had smoke (from excess flux residue). Hopefully if anyone else sees it, they will mention it.

[DENGOH]

I wonder is there method to make all the material dried or settled so that they don’t smoke, for example switch on in High mode for a few days before using Turbo mode. Really don’t feel like to open a newly bought flashlight unless I want to mod it to improve it. But GT is already very very hard driven.

Opening the GT is the new test of strength. I gonna bare hand it. :disguised_face:

I think the chance is high that some might miss seeing the smoke as it is tough to look into the reflector with Turbo mode on or it was dark outside when they switch off to check the reflector. Sure that many switch on Turbo indoor too, but i think most will not switch it on Turbo long enough because it is very hard to look at the hotspot on wall.

Anyway, the smoke might not cause detrimental damage or leave any visible marks if it is not very serious smoking. I just want to have some precautions about it.

The bezel is way harder to open then the head was to remove on both of my GT’s. The rubber mat worked to get both bezels off, but man what a PITA! I would have used my big strap wrench but it’s at work. It took everything I had to get those bezels off! :person_facepalming:

Both are done now, I even changed the other GT’s emitter to the E2 3A I bought off Lexel both the de-domed E41A and the E2 3A are more to my liking.

A few of my Throwers… 12 of them are XHP35’s….

Where is the balance point (Center of mass) in the GT?

Good question! I fashioned a simple ‘seesaw’ or ‘teeter-totter’ to find out. :laughing:

The center of the switch and the center of the tripod hole are exactly opposite each other.

Fully loaded with 8 Samsung 30Q button top cells, the balance point is 1 cm (3/8”) behind the center of the tripod hole.

With 4 cells in just the rear carrier, the balance point is at the rear edge of the tripod hole.

With 4 cells in just the front carrier, the balance point is at the front edge of the tripod hole.

This means the center of mass moves just 1.5 cm (5/8”) in the cases of both extremes.

In short, the balance point is at (or just behind) the tripod hole or switch.

… ToyKeeper …

I do lots of stuff on BLF, but I’m not on the BLF GT team.

For the GT I’ve mostly just chatted in this thread sometimes, and I’m hoping to port some firmware to the GT soon (FSM and its UIs). This will allow it to operate like a Zebralight, an Olight, a Meteor, or run Anduril (my current favorite UI, similar to Narsil).

[Texas_Ace]

We already have a Team account for the GT, it is what was used to post the support thread.

The issue now is that making a new thread at this point would lead to more work for the team with minimal effects on the usefulness for everyone else. I mean people still ask to be added to the list in my review thread, who says people will find and read a separate thread for the GT?

Plus there is the case of it needing to be put together and none of the team has time for that right now. I just started eating solid food again, it will be a little bit before I am ready to do anything more then try to keep up with reading the posts.

I think it would be easier if anything to add a FAQ to the support thread with the latest status updated, since that thread already exists.

Team Members noted.

Who were the members (heart of) involved in the development of the GT?

[Bruno28]

After all the nice photos people have posted of their BLF, I might want to order another. When is the cutoff for the $157 price? I want to see if my first arrived before I order another.

I'd advise to get on the list while the getting is good and available

Ceiling bounce is not a very good way to judge lumen output, its not going to be very accurate

This is another point, the concentrated beam of the GT could also effect the way the light bounced and cause less light to reflect at all, skewing your readings further.

Basically the LED in the GT is driven as hard as is practical for a production light, harder then most other lights, including the tn42 (it is driven at 2.25A IIRC). So you won’t get much more out of another LED, I wish we could. The only real improvement is going with an E2 bin LED for a 7% improvement. Which we could not source for the GT due to a shortage of NW E2 LED’s.

That makes sense to me. Thanks. I found it impressive that i still hit 1.2 million cd even with a NW emitter. I wonder what it would read with a led closer to cool white. my meter is crazy bias to cool white leds for measuring throw. but i LOVE the NW emitter so ill leave it as is. That is till i can get a CFT 90 in there. 5000 lumens and 1.6 ish million cd sounds amazing(just a guess). it wont be cheap but if a driver can be made for it to drive it to its max potential im all in.

a VERY NW emitter to boot.
it makes my other nw lights look cool white
