Hello which 14500, 3.7V Li ion cell is best suited GT micro feeler, how much mA is good ?
I am going to use THESE, by Windyfire …. because I have them. But mostly because they are great cells. They come flattop or button top… I have some of both.
.
Windyfire 14500 IMR 600mAh – Flat Top

Unprotected, flat top. This is one of the best “high drain” 14500 cells available, outperforming even the venerable AW and Efest 14500 cells—check out the discharge comparison picture!

I tried searching in here and didn’t see an answer. Should we get flat or button top for this light?
Thanks for the suggestion on a cell.

I can’t say for sure, I would ‘think’ either one would work. Maybe M4D M4X can answer that question.

 the driver has a raised button with 5mm diameter - so i think most cells would work
but if the shrink does cover the button ....

I think a Flat Top Cell, on the driver can work.

From the looks, a button top is safest. That might be large enough to go off the edges of a flat top contact. There’s enough room in the spring travel for a couple mm of length?

That’s a 5mm button on the driver, a flat top cell is easily 8mm inside the wrap, no problem. Wink

The cut offs on the via’s are at a minimum 8.6mm, and they should be below the level of the button anyway….

Is anyone able to tell me what size MCPCB and driver this light uses?

I’m keen to try a white flat in it. Having not used a white flat yet, would it be ok with the stock driver in this light or would I need to swap it out with a lower current regulated driver?

Ideally you want a 12×7135 driver with e-switch control and those are not common. The stock direct driver could work fairly well because 14500 batteries show more voltage sag than 18650 batteries.

I did not measure it but it seemed a little smaller then a normal 16mm mcpcb. I think you could sand down a 16mm mcpcb to fit though.

A white flat was donated to me recently. Once I know I am done with the prototype I plan to install one in the GT micro if I can make the mcpcb fit.

I estimate exactly 100 kcd, a bit higher if the reflector is really good.

Somehow, I hadn’t read about this light until now. It reminds me a lot of the BLF X5. It was cute, and the copper version is pretty, but ever since getting a D1 I haven’t had much use for the X5 or X6.

Anyway, a quick spec comparison of similar lights…

GT Micro: (manufacturer’s specs)

  • 36 mm wide
  • 105 mm long
  • 600 mAh Windyfire 14500 cell recommended
  • ~400m throw

BLF X5:

  • 31 mm wide
  • 108.5 mm long
  • 600 mAh Windyfire 14500 cell recommended
  • ~333m throw

Emisar D1:

  • 34.8 mm wide
  • 74.8 mm long
  • 1150 mAh 18350 cell recommended
  • ~400m throw

I usually leave the D1 in my purse, soft-locked. It’s small enough I can forget about it until I need it… and it’s not often I need something with more throw. I have it flashed with Anduril, and configured to run in stepped mode with a high enough floor that I often don’t even need to unlock it to take a peek at something in the distance.

Rationally the D1 is the better light, an improved GTmicro with a superior battery, but I really like the shape of the GTmicro, and maybe it helps a bit that it is a bit slimmer and more lightweight.

Well… let’s hope that the GT Micro reflector is better than D1 one

I just got my prototype GT micro in yesterday and I have to say, I like it. A nice little pocket thrower.

The throw ratings they gave are spot on what I got, I got 52kcd and 457m of throw on my sample.

Although the lumens are a bit lower, I got 900 lumens dropping to ~800. They are using VERY thin LED wires right now though and the tailcap springs could be a bit lower resistance.

I told them to use 24awg wire on the LED, that should bump the output up some so it could be rated at 850-900 lumens (technically it could now but that is not how I do things).

The thermals are surprisingly good as well, Took quite some time for it to heat up enough to thermal throttle and by that point the cell was at the point of LVP, so not sure which one it was that caused it to step down but think it might of been the LVP.

I have to say, it looks pretty good for a prototype.


the Emisa D1 is 43000cd & the gt micro is 52000cd ,so in theory the gt micro will throw further?
if that’s true ,then for how long (time) will the gt throw further ? the d1 will run on a 30q @3000mah & the gt run on a high drain 600 mah 14500.

An 18650 will slaughter a 14500, no question. It was never meant to compete with an 18650 based light, the GTmini is for that. This is a smaller version for fun as much as anything.

Although having used it some, I can say it is actually a nice light overall all things considered.

It’s a nice form factor. Small, comfortable, generally sleek. It’s physically pretty similar to a popular Maglite model, and that model was popular for a reason.

Looking back at the X5 though, the #1 request was that people wanted it to use an 18650 cell, to increase power and runtime. The head is wide enough that the wider cell would probably be a nice fit.

On a related note, one of the top feedback items on the D1S (and the GT-Mini) was that it should have maybe used a 21700 cell, for similar reasons.

Yes, I like the idea of 21700 based lights as well, sadly they did not heed my suggestion that the GT mini should be made into a 21700 light.

I think it would of been a great combo.

I really like the Sofrin C8F? that is 21700 based.
