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.
14mm mcpcb
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.
Well… let’s hope that the GT Micro reflector is better than D1 one
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.
+1 on the GT Mini 21700 (and maybe an XHP35 HI as well)
Also +1 on the Sofirn C8F which seems so far to be my all around go to - it has pretty much of everything - enough throw, plenty bright, enough spill, good ramping UI, mechanical forward clicky so no parasite drain.. If only it would've been a single emitter (with the efficacy of the 3 it currently has tho) like a C8/GT Mini and with a more refined beam pattern..
The Swiss Army Knife conundrum, having everything everybody wants all the time… due to the very nature of a flashlight, someone is guaranteed to be disappointed no matter how epic a light is made. Hence, the reason some of us have so many. 
I don’t know if anybody has actually answered this yet, but the 2.5 amp that was mentioned in the early version of the GT manual was just a misprint. It was copied and pasted from the original GT manual. It can be disregarded.
Apparently Lumintop is still inadvertently using that 2.5 amp rating for the Micro. :person_facepalming:
I recieved a Micro from Neal today. It’s pretty cute and pocket friendly. I’ll do a quick review of it.
The quality is just as good as the Mini, just smaller. I have the Cool White version.
Unfortunately I only had a protected Evva 800mah 14500 non-high drain battery in my stash.
I did some tail cap amp draws using the UT210E clamp meter.
Top of ramp - 1.65A
Turbo at 3 secs - 2.75
Turbo amperage dropped fast due to this battery. I thought about buying a Windyfire and wait till it gets in to report my findings, but I decided to rip the protection circuitry off instead to see what happens. There was only a small increase in output.
Unprotected Evva 800mah
Top of ramp - 1.80A
Turbo at 3 secs - 2.90
Turbo at 30 secs - 2.40
I used my Maukka calibrated TA Lumen Tube to measure the output.
Top of ramp - 470 lm
Turbo at 3 secs - 770 lm
Turbo at 30 secs - 690 lm
To measure throw I use my LX1330B lux meter at 10 meters.
At 10 seconds I got 53Kcd or 460 meters.
At 30 seconds the output dropped to 46Kcd or 429 meters.
Not bad for a tiny light running on a not so great battery. I want to order a high drain cell to see what it can really do. 
Parasitic drain was lower than the Mini at 140 microamps with the switch light on and 0.3 microamps with the switch light off. The Mini was 180/20. Did anyone else get a super low drain for the switch light being off? That’s crazy low drain.
A few pics with the Mini:
The rubber button is just a tiny bit smaller on the Micro.
It’s surprising just how small it is compared to the Mini. It makes my hand look giant. Lol
EDIT:
I recieved my high drain Windyfire 650mah button top battery. Here are the updated numbers.
Tail cap amp draws using the UT210E clamp meter.
Top of ramp - 2.2A
Turbo at 3 secs - 4.6A
Turbo at 30 secs - 4.1A
Maukka calibrated TA Lumen Tube to measure the output.
Top of ramp - 650 lm
Turbo at 1 secs - 1100 lm
Turbo at 30 secs - 970 lm
To measure throw I use my LX1330B lux meter at 10 meters.
At 10 seconds I got 63Kcd or 502 meters.
At 30 seconds the output dropped to 60Kcd or 490 meters.
thanks for sharing!
