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.
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?
I come to 2 blinks and then 8 but don’t know how to confirm that, it won’t memorise…
Who & what is this referring to??
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.
Now you should be set.
Here is my video showing how the menu system works.
Refer to the GT Mini menu for its options. I use the Q8 menu in the video.
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.
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.
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.
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.
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.
Ok. They sent me uncorrect manual.
All the printed manuals are incorrect. Was this not mentioned in this thread? We had a discussion about it in the other thread I linked to.
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 AUX LED: 10K <1%
C1 10uF X5R or X7R
C1 0.1uF
FET LFPAK56 (SO8 also fits same pad)
