This is just getting crazy now…

Yes… it is getting somewhat comical indeed…. :smiley: . :wink: … :+1:

Has anybody tried disassembling the GT Mini? How hard is it to remove the driver for purposes of updating the firmware and replacing the integrated switch? I think replacing the switch is the easy part. I’m more concerned in pulling out the driver and putting it back in.

Dale opened his as soon as it arrived.

You’ll need to remove the bezel, lens, and reflector in order to unsolder the LED board so you can pop the driver out.

Dale’s bezel had plenty of threadlocker but others have reported little or none.

Dale also said the driver still goes back snugly after being removed and reinstalled.

I’ll be flashing ToyKeeper’s Andúril UI to mine as soon as it arrives. It’s en route but seems to have taken a holiday in Chicago. :smiley:

Copy that. Thanks. I’m expecting the bezel thread is glued, considering the flashlight is made by Lumintop. So the technique of removing the driver is no different.

Can someone post picture of head spring on this light, my looks some kind of strange, it is distorted and unequal :cry:

Mine looks the same. I don’t think it’ll have any adverse effect on its performance though.

That looks like one of those new ’Cattywampus HP Springs’…… (“HP” = High Preformance) :+1: . :wink:

Replacing the switch will be the hardest part. Followed by getting the bezel loose. After that it should be a snap.

Ok, thanks I just asked, light is performing normal, just was curious.

/\…. :+1:

Wait, it’s not a gold plated spring.

Something seems… off about your sample.

mine is not gold plated either atleast the head spring isnt but tailcap is gold, but his just looks awful, mine looks alot better.

I received the GT Mini and holster today - ordered from Neal August 7, 14 days ago.

Real nice C8 style light!

More compact then the C8 actually, with a wider head and more throw. Illuminated side switch and ramping UI are a real plus for me. Well done Lumintop! :+1:

I believe a 26650 tube would have been just right for this head and would have been closer to the GT big brother proportions?

good to hear patmurris!

about the spring
neal says Driver spring is berylium bronze

Is that CataWomped berylium bronze—- I think that makes it handle more current

Oooh what kind of beryllium copper are they using?

That would explain why the GT Mini can still attain very high lumen numbers without a spring bypass on the driver spring.

One of my GT minis arrived today. It’s really nice! :partying_face:

I quickly opened it to flash ToyKeeper’s Andúril UI onto the driver.

The bezel had a good amount of blue threadlocker, so I used a vise and leather glove to remove it.

The driver came out easily. I dislodged it with a rod fed through one of the MCPCB’s screw holes.

With my light’s switch at 12 o’clock, the screw hole at 4:30 lines up with a blank spot on the driver near the positive wire’s solder connection.

I’m curious if those four holes are in the same place relative to the switch on other samples.

The driver had small traces of white adhesive, but it went back into place snugly.


I received mine today. The head is slightly larger than a C8 with a 42.75 mm interior reflector opening versus 38 mm for the C8. The lighted side switch is alright even with the evil green smile effect.

The best I can get is about 110 kcd but given that it only draws 4.5 amps on turbo I’m not terribly disappointed. One thing I noticed is that it’s not well focused and this could be the reason why the throw doesn’t live up to spec.

The only advantage it has over the D1S is the ability to attach a lanyard (comes with the package). The D1S out throws it and has full output at the top of the ramp.

For the price I’m relatively happy and it will find a good home I’m sure.
