To update my situation, I received my replacement head from Neal today, very happy with his service! Fingers crossed this switch will not have issues. It does feel firmer and a more positive click but that might just be because it’s new.
my replacement works perfect one month later or more so guess they did a better job second time. And yes the button feels better not because new its because they changed something i guess, older was worse.
Anyone else having any type GT Mini switch problems besides the people I mentioned above??

The only reason ToyKeeper built a calibration tool in Anduril was to make it easier at the factory to get consistent thermal stepdown temperatures.
It was originally because people complained about the “hold until hot” method being obnoxious. Factory calibration is a bonus though. It’s also easier to implement, and takes less space.
To make things easier in the future though, I’m adding a factory reset function with auto-calibration. So people shouldn’t really need to enter the temperature manually unless they want to fine-tune it.
I am a little disappointed with the attitude of Neals. I bought a lot of flashlights from him for a lot of money, and to submit my problem with a switch in GTmini, he offered me a $ 5 rebate. It does not change anything. Head replacement or even the driver may help. At the most I will try to unscrew the glued frame. I do not react to my next e-mails anymore. It’s a pity, because until now I was very happy with shopping with him. Well packaged and good contact, but you can see, as most of the sellers from the east, with the problems their attitude changes completely. I’m sad.

weird, most of us that asked including me for replacement head was no problem to get? just ask again, say u just want a replacement head like everyone else here that bought the light during group buy got,, its clear that a large number of lights from that batch suffered from a faulty switch..
I have already sent a few e-mails, I will not be more. There are many sellers, not just Neals. So in the future I will simply buy from someone else. I still have a big list with purchases, so its his loss.
ok i understand its weird he seems like an ok guy to deal with, not sure why he is ignoring u to send new replacement head… yeah try buy somewhere else if hes not willing to help i would do same.
Your camera angle is incorrect, the bezel is not parallel to the camera lens, thus a wide area of the bezel is pictured on the lower bottom and no bezel edge showing at top. That being said the led looks to be uncentered to some degree.

I come to 2 blinks and then 8 but don’t know how to confirm that, it won’t memorise..
If you are still in ramping, you look for 2 fast blinks then one slow blink, click once and confirm the light blinks when you press the button. Then let it finish.
Now you should be out of ramping mode and into mode sets. Now you go back into the menu and wait for 2 fast and 2 slow. Now you have to click 8 times. Again, make sure each button click gives a blink of light. Then let it finish the menu.
Mine sometimes don’t respond to the switch. Is that the switch problem you are talking about?
Seams like it does it a lot in the configure menu. And when going from turbo to lower level, sometimes it just turns off like its not counting the 2 clicks.

It always turns off from Turbo to a lower level. That’s how the UI works.
I’m not sure who you are asking about the switch. Some peoples light had a switch that didn’t always make contact.
I have had lights with perfect switches sometimes act like it doesn’t make contact when I’m in the menu setup. This is why it’s important to look for the confirmation blink. Sometimes I may have to click four times just to get the two blinks that I want. I don’t know why it does that. Luckily I pretty much never have to change anything in the menu once I get it set up the first time.

Refer to the GT Mini menu for its options. I use the Q8 menu in the video.
Thank you very much. The main problem was that I didn’t know that first 2 blinks didn’t count.
I managed to get into Mode set no. that I want and to enable mode memory, and want to know more about this 100% power modes that are used in Mode set no. do they use FET on all 100% power modes, I choose mode set 8 so I’m little confused with pictures in your videos, so don’t know it is using FET ?

That’s why I said don’t use the pictures in my video. You need to use the manual for the GT Mini.
Yes, at 100% it is using the FET. I think this is a 2 channel driver with only one 7135, so anything above about 200 lumen should be from the FET. Maybe someone can confirm that.

Gt mini is a FET+1.
Just to have the info posted heres the BOM (I cloned the GT mini driver when making my FET+1 drivers)
R1 FET Pull-down: 100k <1%
R2 Gate resistor : 47ohm
R3 input filter : 4.7ohm
R4 voltage divider high side : 910k
R5 voltage divider low side : 300k
R6 AUXLED: 10K <1%
C1 10uF X5R or X7R
C1 0.1uF FET LFPAK56 (SO8 also fits same pad)

RIP SPC Joey Riley, KIA 11/24/14. Now I am become death, the destroyer of worlds.
Sorta. ToyKeeper has explained it all in intricate detail before but the FET kicks in with PWM over the ceiling of the 7135… the 7135 keeps putting out 100% along with the increasing level of the FET right up until level 7, where the 7135 is cut off and it’s 100% FET.
Not so easy to say how many lumens the 350mA of the 7135 chip produces as that number will be dependent on the emitter used, cell used, efficiency of the circuit, a number of things.
Edit: Mine (GT Mini) has a Samsung LH351D 80 CRI 5000K emitter and makes 168 lumens at the 7135 chip ceiling , from an LG HG6 20650 cell well rested.
EditII: Another light using an XP-L HI from a 26650 makes 164 lumens, also well rested using a LiitoKala Black.
EditIII: My little TK05 using a 14500 cell and the 80 CRI Samsung makes 156 lumens at the top of the 7135 chip.
EditIV: On an extreme end, my 458 Ham’r is making 862 lumens at the top of the 7135 chip output.
While we are talking about a single emitter here, my Quad D1S makes 531 on the ceiling of the 7135 chip. So there are indeed variables…
Thanks JasonWW for reading every post in this thread and setting me str8 on the misprinted manual. I only recently received this light I have not had a chance to dismantle it.
I do like the light but the error/glitch in the UI is annoying.
my replacement works perfect one month later or more so guess they did a better job second time. And yes the button feels better not because new its because they changed something i guess, older was worse.

What you do to memorize a mode set no. from UI of this light ?
I want to set it 0.7, 2.3, 5.2, 11, 25, 41, 70, 100 %, but long click does nothing as far as short click ?
Your camera angle is incorrect, the bezel is not parallel to the camera lens, thus a wide area of the bezel is pictured on the lower bottom and no bezel edge showing at top. That being said the led looks to be uncentered to some degree.
First you go into the setup menu and switch from ramping to mode sets. Exit menu and confirm change.
Then you go back into the menu and change the number of levels to 8.
Do you need instructions on this?

If I run mine up to a mid level and double click it goes to Turbo, and if I double click from Turbo (blinkys disabled) it returns to the mid level.
Sometimes it just turns off with the double click from Turbo.
Edit- this only happens when I am at the top of the ramp.

My manual says mode sets
1-6 100% = 2.3 A LED drive
7-12 100% = 4.5 A LED drive
I am assuming they are using 6 7135 chips and a fet.
Driver: 17W, 4.5 A FET driver etc etc
Been playing with mine some more tonight.
I only get double click error from Turbo if I am at the top of the ramp.
Edit. Guessing the jump from 2.3 to 4.5 and back.
I think your looking at an incorrect manual.
Go to this thread and you will see a link for the manual. I’ll add the manual link here as well.
http://pballandmore.com/Download/2018/GTmini_user_manual_V5.pdf
If you look at the back of the driver there are no 7135 chips. So it can’t have 6 chips. There is no room for them on the other side.
What type of error do you mean? The brightness should go up a little more when you go from top of ramp to turbo.

Thanks, thats what I was thinking. So any brightness level above the 7135’s 0.35A current (about 200 lumen) will be going through the FET.
