I got the GT mini today. Overall it’s a really great flashlight, but in my sample mode programming sucks. I’ve managed to set “UI - mode sets” and then I tried to program mode set. Here’s what happens:
1 click (in programming mode) - 1 mode (moonlight excluded)
2 clicks - 2 modes
…. same pattern - number of x clicks gets me x modes…
7 clicks - 7 modes
8 clicks - 8 modes (first WTF?)
9 cliks - 4 modes
10 clicks - 5 modes
11 clicks - 6 modes
12 clicks - 8 modes
That’s neither NarsilM v1.2 mode sets, nor those in manual I got with the flashlight. Anyone had same situation?
Everything looks correct. IIRC the manual that came with the light is an old version based on a different light. Look in post 1 here for the correct manual.
I have not fooled anyone, this is my measurement of my art. They coincide with the measurements of my other flashlights. Of course, this is not a laboratory, so only information is loose. It depends on you what you do with it.
As I said, take all lumen readings with a grain of salt. Nobody has “actual”. All of us here at BLF are just hobbiests. We are not testing labs. Some people might measure 1100 lm, some might measure 1600 lm. It depends on the device they measure with and how their device is calibrated.
Based on it drawing 5.5A on turbo and my TA Lumen Tube measuring 1240 lm, I would definitely say it meets or exceeds the factory 1200 lm rating. No worries about that. I also measured 148Kcd = 769m which is above the 135kcd spec. This is using a Samsung 30Q. Here are all my measurements if your interested.
Differences in measurements result from many reasons. Not only from the methodology but also from the differences between the various models. It can be affected by the ambient temperature, the battery used, the centering of the LED …
GTmini has a FET driver and the internal resistivity of the elements is very important here. The manufacturer gives 17W and 4.5A. My GTmini with Samsung 30Q received 5.8A (clamp meter). This is one of many possible reasons that the end result may vary. Measurements are made with the X-Rite Eye one Pro calibrator which is more accurate than most cheap light meters. Thanks to this, I can also precisely specify the color of light which in my opinion is one of the most important features. If someone thinks this is not very reliable, then he has such a right, but to call me a liar?
