Ok, problem solved - thanks JasonWW! 
Are all those “100%” modes driven DD with FET?
Good point, I forgot about that.
Yes, turbo / 100% are the same thing.
OK, thanks!
Does anyone know what LED they are using in the NW version??
I just jumped on this light without doing much research, thinking I would have to swap out the LED anyway.
After having it out a while tonight, I love it. I want to order some more LED’s of this tint.
Pierced the woods almost as well as my NW modded M2X Javalot even though it didn’t have the lux.
4000k XPL-HI in the 5A/5D chromacity bin, so under the BBL.
Thank you, Its performed well in the timber.
wow that is very good specs for a 4000k emitter. almost 1400 lumens is accurate also ?
It seems most have gotten about 1250 lumen for the CW. I would expect the NW to be a bit less. Assuming you use a good high drain battery.
You have to take all lumens ratings with a grain of salt. 
okay that sucks komeko u tricked me 
i thought it was actual lumens he got from his.
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.
okay but if not accurate i dont understand why post numbers that doesnt represent actual ?
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.
Yes i understand, was just asking, i realize even cw maybe not topps 1300 lumens, its a nice light i really enjoy using mine.
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?
I think Mortuus was just confused with 2 different lumen measurements. No big deal. Nobody is lying.
Tell me about the eye one Pro. Is it just for measuring color or does it also measure lumens?
This is a calibrator for monitors:

Thank you very much komeko. This thing holds its own against my 5000K M2X mod.
I am very impressed with it.
What size driver / MCPCB does this light use?
