Man that sucks about the engraving on the side. That text is really awful. And now realizing the driver is glued in…
I said I was interested in 2, but I’m only ordering 1. Hopefully the NW tint isn’t too yellow.
I think I got the cw
Teacher, can you confirm where you saw these emitter tints at? I can’t seem to find them in any of the threads or reviews.
Does anyone know what emitter bin comes in it?
I ordered CW but of course I’ll change it… 
I will, at the very least, change the emitter and flash Anduril to the driver… I might end up putting an XHP-35 in it, who knows?
If the long tube can take it, I’ll probably bore it for a 20700 or 21700, depending of course if it can take either. I have a couple of XP-L HI V3 3A bare emitters and some boards, might even slice an Samsung LH351D like I did yesterday. I’ll figure it out, one way or 3 others…
(Edit: Come to think on it, I DO have another SBT-70 left over…. )
Thanks Martin, that looked pretty good on your video. I’ll go with that…… 
placed my order for 1 NW GT-Mni 
Here ya’ go my friend. It was from M4DM4X. No idea about bin.
Thanks Teacher! Looks like I will try the CW emitter.
Thanks Dale……
Let us know how hard it is go get the glued in driver out too… 
.
Hopefully the bezel & battery tube will not be glued. :person_facepalming: . 
My pleasure Yourrid! That is what I am going with also.
Martin says he thinks that is what he had in the Prototype when he made the GT Mini video.
Interested

Does anyone have details about the driver, like the circuit design and ideally also source code? If it’s using NarsilM, there should be code for the GT-Mini version available since it’s a derivative work of a GPL-licensed project.
Code would be the most helpful thing for getting Anduril to run on it. An actual working unit with an unglued driver would help too, but probably isn’t necessary if there is reference code.
About the earlier discussion of lumens…
There are several different units in common use, and all of them are called a “lumen”:
- The main one is the ANSI standard lumen. Maukka has calibrated equipment which uses this scale. I think djozz may be using it too.
- The most common on BLF is the Zebralight/cpfselfbuilt lumen scale. It usually runs about 40% higher than ANSI lumens, so a 100-ANSI-lumen light will typically read about 140 lumens on a zebraselfbuilt scale. I think this is what I’ve been using, since I calibrated my light box to match selfbuilt’s numbers and Zebralight’s numbers. I think it’s also what DB Custom uses, and several of the other modders here on BLF.
- Texas_Ace light tube lumens. I hear these may be higher still, but I don’t know the details.
- Every other person’s home-calibrated light box. These all differ from each other, so the numbers are only really comparable to other measurements by that same person.
Additionally, there are other factors making this more complicated:
- Emitter lumens vs OTF (out the front) lumens. A bare emitter measures higher than one housed inside a flashlight with various optics. I think this may have been the origin of the Zebraselfbuilt scale, in part. The OTF Zebra lumens are often pretty close to the ANSI OTF lumens, at least in some lights.
- Measurement timing. Numbers measured at start are usually higher than measured at the ANSI-standard timing of 30 seconds.
- Sag. Output sags over time in a lot of lights. ANSI runtimes technically go until the light sags to 10%, IIRC, but this value is misleading. 3 hours at 1000 lumens may actually be 3 minutes at 1000 lumens and then 2h at 200 lumens, then 57 minutes at 101 lumens.
- “Chinese lumens / Ultrafire lumens”. Marketing people like to make up numbers to try to make lights sell better, especially on cheap items. Often times they’ll take the emitter’s maximum rated ANSI emitter lumen output and claim the product does two or three times as much. This number has very little relation to actual real-world performance.
From what I can tell, the GT-Mini will probably make about 1200 OTF Zebra lumens, slightly less than the Emisar D1S’s 1300-1350 OTF Zebra lumens. The number is probably lower on an ANSI OTF scale though. And it’s almost certainly not 2000, unless we count Ultrafire lumens… in which case it’d probably be about 2500 to 4000.
Since I have plans to mod my GT mini, I’ll pull the driver and send it to you when I get the light TK….
It may be totally unnecessary. The manual indicates it’s running NarsilM 1.2, I think. It might be totally unmodified from what’s on the big GT.
If that’s the case, everything might “just work”. So, definitely try it first… Also, I may be travelling for a while and may not be able to receive packages or get much done. So I hope things will work as-is without any changes.
Which one do you like more?
