(prototype) the GT Mini

Thanks! Another message sent to Neal. I'll keep you updated.



my early sample was 16mm, buzt ZozzV6 had several open and says they are 20mm

i bought a SST-40 led for my GTmino but i can’t seem to remove the bezel, how did you guys do it?

Hi, Is it possible somehow fix or rotate rubber switch cover, because it's rottated too much to the left?

You can pry the press fit retaining ring up & rotate the switch cover / switch to your liking. That might be more trouble than it is worth though…. but that depends on how much it bothers you.

You mean i need to rotate a silver ring with some tweezers and not a rubber cover?

No, the “silver ring” (retaining ring) is holding the “rubber cover” in place. To rotate the rubber cover you must loosen or remove the retaining ring. Then rotate the rubber cover & press the retaining ring in again to hold the cover.

The retaining ring is a ‘press fit’ so you must somehow pry it out to remove it.

IIRC someone in this thread showed how they did it, pictures included. I do not have time to hunt it up now. But if you have not found it by the time I get back home I’ll find it & post it here.

Sometimes you need to use a heat gun to heat up the bezel and soften the threadlocker, then use a pair of rubber strap wrenches to rotate in opposite directions. The amount of threadlocker will determine how tight it is and if heat is needed.

Sometimes even a heat gun is not hot enough and you need a blowtorch, while being careful not to discolour the anodisation.

Is it normal that when a gt mini is turned off, led still glows like a moon mode, don’t know maybe 1 or 2 or 3 lux, so i can light a watch and see what’s the time, also can clearly see a spot on a white wall.
Even if i lock a torch with a 4 press of a button, so the green led on a button goes off, but xpl-hi led still glows a little, so it’s impossible that an xpl-hi led is iluminated a little from a button led.
Do you think i need to RMA it , because i have befor this one another gt mini NW, but i didn’t see that a main led shines even if a torch is off.
In manuals it writes that a parasitic drain is around 27micro A but on my torch parasitic drain is when a torch is off 4.3mili A.
Is this a problem with a driver or with a led?

if you lockout the tailcap for a minute and then reconnect - does the led glow before you hit the switch first time too?

Yes, as fast as i turn down a tailcap, led blinks two times and then dim glows, i don’t need to push a power button.

No, that is not normal. When the light is OFF, the LED should be OFF.

It’s a problem with the driver. The led is just a dumb device with constant positive power going to it. It’s the driver that is responsible for the ground side. Apparently there is some current leaking through the driver allowing power to flow (like a bad 7135 chip or capacitor for instance). 4mA can run a battery down pretty fast. I would see about getting it replaced.

Any plans for an XHP70 version of the GT mini?

The problem can be under the led also, if there is a minute short between led- and the central pad (which is connected to ground), a small piece of dirt is enough to cause that, the led lights up. Is it really more than a lumen? (you can get a visisble illumination of a watch down to 0.01 lumen, in which case the drain is 0.03 mA which is totally negligable.

That’s what their ODF30 is. It’s got a bigger battery of course, but very similar.

I just received my GT Mini NW from Lumintop Aliexpress store and I am so happy with it I cant even express it with words!Extremely well build very handy pocket thrower with perfect Kelvin emitter for me!Wicked flashlight!

great!

I just received one also. I am really happy with the light! The size, the distance the beam throws, the tint of the emitter, the UI. Pretty cool that I have a light similar to the BLF GT that I can carry in a pocket. I love BLF! Thanks to all for the effort. Regards.
