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?
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.
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.
