Two posts. Two GT’s. That’s an amazing track record so far.

If I remember right, there was a SupFire light that had a handle that mounted to the tripod thread

Niteye EYE30/40 had this! 25$(+ shipping)<-click the pic…!

that looks perfect!
wonder it the threads will match up ?

Damn, I’m going to regret joining this forum real soon ( I got my first LED flash light only ~ 2 months ago, a brand new old stock TN32, got me addicted to LED flash lights already ). Please put me down for a 2nd GT ( even if I didn’t get the first one yet ), I should be already in the list somewhere around the position number 11xx .

PS: Happy New Year to everybody ! I wish everybody and their close ones to be healthy, the rest is bonus

[BrianK]

A happy and healthy 2018 right back at you sunfire!

Yeah, there are no membership fees on this site, but it will still cost you some money from FAD (flashlight acquisition disorder).

@BrianK

R/C I googled it and bing kept coming up. Universal Grab Handle - Search which handle did you have in mind?

Sorry BrianK, I was working on an animation.

The search was a "general" search for a velcro strap-type, that wraps around the battery tube at two points. Mainly as ideas from products made for other things. If you look at the images there are universal grab handles available that are used in off-road vehicles, as grab handles. They are adjustable for 2"-3" diameters, and would wrap nicely on the battery tube of the GT, I think.

My idea may not be for everyone. I was merely trying to help find what's readily available, and share my findings.

EDIT, Your search is done through "Bing". I searched through "Google". When you search for Universal Grab Handle, check images to see what's available.

This is a Universal Grab Handle. There are many types and styles 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.

[Cranky64]

Back home from the holiday and I got to take my light out. Man this is the brightest beam I have seen. I have a nice light on my boat but this thing is crazy! I have two questions for the group.

What is the life expectancy of the LED?

Has anyone figured the illuminated circle diameter at a given distance?

Thanks

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.

Outside the team?

@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 migth do that too. :person_facepalming:

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….
