Lumintop GT micro

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….

Saw on facebook that according to Neal its ready to order from him now…

SWWWWWEEEEEEEEEEET

Thanks Martin!

Ordered already… cool white and 1000mAh battery (because I don’t have 14500s around)

Ordered , thanks Martin .

Will these do for the GT Micro?

Enercig (Tensai) TN14500HP- 650mAh 3,6V - 3,7

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 12x7135 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.

17mm driver

(on my prototype)

Wow, will anyone sell me the driver?

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.
