Question, I ordered mine on March 1st and received email from Neal when I emailed him that it was shipped on the 17 yet when I check the tracking, it still says label not yet created. Should I email Neal?

I would email Neal on that...

 

So, I re-assembled the light, reflowed a black flat on the stock MCPCB. Didn't check amps but with fumbling around with getting it centered, I was able to hit 112 kcd measured at 5 meters. It still has a black spot in the middle at closer than 4 feet from the wall, but looks pretty good outdoors. I'm using a decent performing Imren 700 BT cell. It gets pretty hot quick so the amps are probably up there. It's got a fairly large corona, but this is the first black flat (or white flat) mod I've done.

I used kapton tape around the LED (no centering piece), and believe it or not, silicone wire inside around the base, and between the glass and reflector to center it and get more downward pressure.

112kCd is a sweet number ! Mine does 105, but at only 3,2A…
I ordered some Enercig 14500 on nkon.eu, they should be able to sustain 4 or 5 amperes, throw might be interesting then !
Could you check the current drain on yours ?

Can't yet measure amps, this evening. I'd suspect mine is more like 4-5 amps based on how fast it warms up. Measuring at 5 meters  is tricky though, should be easier at 10+ meters.

Some more pics:

All cleaned up, glue removed, red wire replaced::

FET lurking under the MCU:

black flat mounted. You see what I mean by the paint? Tried scraping it off at the top shown below but couldn't expose any color/coating underneath:

The centering piece is too small of an opening to fit this LED, so:

See the red wire? It helped in centering and focusing, still not perfect:

I don’t see a black spot, but I do see a yellow tint in the center of the beam. Not obnoxious or anything, but just there.
I’m running an Efest purple button top. 650 mah, 6+ amp continuous draw.
I really like this light. It feels a little weird in my hand at first, since I’m used to my Lumintop Tool AA 2.0 and my Sofirn C01s, but it works just fine. I ordered the holster with it, and am looking forward to wearing it on my belt for EDC for a while.
It’s getting dark out now, so heading outside to do side by sides with my GT Mini and the Lumintop Tool AA 2.0.
PS: I got mine a couple of days ago. It seemed to get hung up in LA for several days but it’s here so I’m happy.

Are your WindyFires button top or flat top?

Windy fires are buttontop and efest are flat. I tried the windyfires again and in fact they do work. I dunno why it didn’t work the first time. I’m pretty sure I had the tail cap fully tightened. Maybe the body wasn’t.
The windy fires have an extra 100 Lumens on start up vs the Vapcell. But I still prefer the Vapcell because of the 1000 mah.

Ok.. thanks for the info. Thumbs Up
I gotta get me a couple of those Vapcell 1000 mAh.. that extra capacity sounds good. And just loosing 100 lumens is not to bad given the extra capacity.

Has anyone tried an xhp50 3v in the micro yet?

I love this light, perfect for EDC on the belt.

Doesn’t make sense… You would have to find a 14500 that is able to deliver more than 8A to justify the XHP50 over the SST40

But then again, the 3V 50.2 can deliver far more lumens than the SST-40, soooooo, a top 14500 pushing a 3V 50.2 should give an interesting boost over the use of an SST-40, AND a sliced and diced 50.2 would be even more interesting! Wink

Nothing back from Neal. I have chased him twice. I guess its Paypal dispute time.

I just noticed Vapcell released a 14500 650mah 7A button top battery 7A CDR, 13A max discharge current. Seems to be the best high drain 14500 available on the market. I previously bought their 14500 1000mah batteries, which is the best high capacity 14500 on the market, and I tested them to be legit specs.

Has anyone done any measurements with this battery on their GT Micro or with a similar high drain battery? I’m wondering if the new Vapcell will be able to manage 4.5A in this light. Thinking of buying one to put a White Flat in there.
