Also got one of the MNKE 26650 IMRs. The blue ones from Gigainternational are "fakes" and don't even challenge a NCR18650A. Lets see how this bad boy stacks up. I heard it got up till 4.2AH in discharge tests but could not google the info.
Super nice flashlight.
This is the post on CPF
"I've tested one of each type at the 337 mA discharge rate which is the only rate which can be executed on my older MAHA MH-C777PlusII charger. The discharge routine automatically cuts off at 3.0V I was very happy to observe that the MNKE delivered 4269 mAh while the Batteryspace delivered 4013 mAh. The voltage drops during discharge appeared proportional."
4269mAh @ 337mA down to 3V. Super nice, even though some might want 20A discharges from such a cell.
These are the official discharge graphs offered by MNKE
Ahh thanks buddy. 
The diff between this and the regular JM07 is that this one has 9 fins whereas the JM07 has 5.
And I always dig gun metal colour/finish + NW esp T6 3C.
I look at lights like the Shadow TC6, RRT-2, even Kingpower big head.....steam!
Just waiting patiently for the Zebralight SC600w (neutral white)
I wish I could be patient, but its been a long wait. In the meantime, I may just have to get one of these. 
EDIT: There goes more money. :p
I was looking at that JM07 last night and again admiring the design over the JM05. I didn't even notice it's the "PRO" version. Although I like the body style (lines/ridges) of the JM05, the tail cap stinks. It seems they could just ditch that model and stick with the JM07. What do you suppose it's driven at?
I like it a lot - and I'm a BIG fan of Shadow - but I haven't invested in the 26650 format yet.
With the free 18650 to 26650 converter, you can delay the jump to fatbatville until you're ready. I, for one, am smitten with this gunmetal beauty and damn you 2100 for repeatedly putting up awesome lights that beg to be purchased. You're killin' me, man.

Like most of the Shadow flashlights @ 2.6A , they state 800lumens, which is correct for that current.
Well it seems Intl-Outdoor are offering the 26650 to 18650 conversion tube for free. With a 26650 battery the output would definitely be regulated for a longer time, especially on the MNKE IMRs which are supposed to give currents up to 20A.
I really like that it has a low voltage warning function.
Hikelite, That's what I figured. I just wasn't sure if they do any different with 26650.
Foy, I thought about just using the sleeve for a while but then I know it would bug me having a 26650 light and not utilizing its full potential :P
weiser -
I hear that. No way could I allow any capability to go unused. If it could accept a 26650 battery, it would eat at me until I filled it with as much juice as possible. I have these old D-to-AA converters (never use) and one time I put them in one of my 6D Mags. Holding a 6D MagLite with 6 AA batteries just feels wrong somehow.

Can you please tell us more about this light? I love 26650 format!
I don’t have the numbers in front of me, but I got around 4100mah on the MKNEs, 3800mah from the Batteryspace ones and 3500mah or so from the Bestinone.net 26650s…AND I think that was @ 3 amps. So that sounds plausible. I may have to break out the CBA and do some new battery tests.
There's still no shame in running it on 18650s. The size of a 26mm cell light just feels better in my big mitts. Now I can go sell my expensive Fivemega 26650 p60 host over on CPF and have money to put in my pocket. :p
4100mah @ 3000mA , wow nice.
The other guy 4269mAh @ 337mA
And still, the cell is rated 4000mA. I wonder if they rated it 4000mAh based on 1C discharge.
There's something about the name of a website being "Good Luck Buy" that doesn't instill a whole lot of confidence. Like it's telling me "Thanks for your money, now good luck!" :P
What's bugging me is that I just came across those batteries today for like $7 or $8 I think. I can't remember if it was an ebay seller or a website I happened to come across from browsing.
Hi everybody, I’m looking for my first flashlight with rechargeable cells.
This light has 3 levels (100%-30%-5%), is it in lumens around 800-240-40 or should it be estimated some other way from power? Would this give noticeable longer run time in medium mode than similar light with 1x18650? What about in Hi mode?
Can anyone tell difference with JM07 PRO and JM07? Something must be built differently to explain 50g weight difference in same size.
Hi pumpuli
Yes the 26650 will give you more runtime. 4000 mah vs 2400-2600mah
For example those MNKE 4000mAh exceed their rated capacity when 337ma current is drawn from them and the same when 3000mA current is draw. Based on what these guys have tested.
18650 2400mAh aren't really 2400mah when discharged at 1000mA current.
And yes it will give you more noticeable runtime in medium mode.
Your estimation regarding the lumens is almost good. Even tough they refer to the max current not max lumens. 100% is 2.6A so everything derives from that. So 30%- 780mA and 5%-130mA
They usually state these percentages based on how the driver is manufactured. The currents that I have mentioned above might not be the same when measured with a DMM since the driver uses Pulse-width modulation to achieve that 30% and the DMM cannot accurately measure that type or current.
I guess it's 800l-300l-50l.
The modes are very nice spaced.
Thank’s a lot Hikelite for great answer!
About JM07 PRO and JM07. Basically they look the same light. Does anybody know if there is any difference in reflectors? I’m looking for a flood light, not thrower.
All 2100 states in post #3 of this thread is that there are more heat fins on the PRO version. I compared the descriptions myself and couldn't find any other differences. Being that they're selling them for the same price the PRO is definitely the way to go. You get a nice gun metal finish and supposedly better heat dissipation.
Your welcome pumpuli.
As far as I can tell from photos around the internet both flashlights have a light orange peel reflector. Taking a guess that the reflector is 37mm (the head being 42mm) you won't have a thrower neither a flooder. But it all depends what you think a thrower is and what a flooder is. The flashlight will definitely throw better than 26.5mm reflectors but it won't have that small and super bright hotspot in the middle like a thrower. Anyway these are only speculations.
