Thanks one more time, for your hard work and dedication to help!
One problem i see, is the overall size of the maglite, and shipping to EU, what model it was exactly? they are big as far as i know or i’m wrong?
Terrifically sharp photos, considering all the giggling you must have been doing. 
It’s a 2D Mag Light, originally designed to run 2 D sized alkaline cells. 57mm overall dia at the head, 258mm long. About 196mm is battery tube at 40mm dia. Quick tape measure numbers.
Ah too bad, its fantastic otherwise, i need something compact ~ 150mm long.
How much run time do you have to have? I recently put an SST-90 in a FandyFire Rook…3 14500 cells with 1 emitter. 1700 lumens but short run times as the SST-90 is not at all efficient. Same light with an MT-G2 might be interesting, would be floody, would have to make the 3 cells series instead of parallel but it’s doable. Smallish light, fit’s in the hand nicely.
Aww… That’s just my latest plan: a 3x D-cell silver Maglite with an MT-G2
Would be so cool with 3x 32650 
There’s a possibility that the 2D Mag could be modified to fit within what you’re asking. Chopping the battery tube to accept 2 26500’s and removing the side switch in favor of a tail cap mounted clicky switch would probably have the light right about at that 150mm while the head and all other components would remain the same. I’ve never chopped a Mag, but know quite a few folks here that are very good at it. TexasLumens is one of those. If you can’t find anything else that fits your requirements, you might give him a holler and see if he’ll modify the base light for you, I could then finish it with the driver and pill/reflector/star/emitter combination if he’s too busy. Something to think about anyway. I have a 1D chopped Mag that is symetrically awesome! 
So a build like I described above would be pretty darn cool.
Edit: Might still be too long, as my 1D is 185mm with the side switch in place, and it uses a single 32650 cell.
Oh i should have mention that i only use 18650 cells, sorry about that! i totally forgot. I need something like edc, which will be flood monster, and would run on 2x 18650, if you got any ideas and you are willing to do the mod, please send me pp
That puts you squarely back into the Solarforce K3 camp. That one’s easy, gives very decent output right out of the box and has comparitively good run times. It can be modified of course, at the expense of run time.
I’d strongly suggest you pick up a K3 head and L2P body with extension, they sell it as a ready made light for a decent price and ship to you wherever you are for $2. $73.99 plus $2 shipping. Can’t beat it.
I don’t care about runtimes bro, around 40 mins is fine for me, i’m not a heavy user, i just want something i can take with me and won’t be too bulky
Solarforce K3 how long it is? and will it work with Protected 3100/3400 mah batteries?
For $80 you’d better off to buy multi-XM-L2 flashlight, for instance the Supfire M6 from RMM if you are living in USA. He would do all the mods for you for around $80 with 4000+ OTF lumens output. It has a Coke can form factor as well.
Tint wise there are neutral white and 80+ CRI option available for XM-L2, just let Richard (from mtnelectronics) knows what suit you the best.
I don't believe you will find or build any light running 2 x 18650 batteries at 150mm long. I'm a little confused as the MTG-2 requires 6 volts so unless you use a boost driver for 1 battery and a very short run time it will not work. 2 x 18650 unless side by side will be around 140mm long just for batteries. So this leaves about 2 cheap lights as hosts that have been mentioned already to use in this build.
Will it be total flood?
Oh ok then, what about ~ 165mm?
Thats why i wanted some strange form-factor like the TK 35.
PM me the build thread when you start. 
Haha, maybe something like the TK 35 form factor?
I know what you are after, but I honestly think you are getting yourself a little mixed up with what is available and possible.
At present it’s a bit like asking for 7 seat Minivan space, luxury SUV comfort, 4x4 off road ability, supercar speed but in something the size of a compact hatchback.
Basically it ain’t gonna happen and you’ll have to compromise somewhere.
When you said EDC, could you clarify as many people consider EDC to be pocket friendly (trouser pockets) torches. For me this rules out something like a C8 or an SRK. While both of these will fit in a jacket pocket, they are too big to carry all the time. The SRK loaded with 4 cells is also quite heavy too.
The reason I say this is quite simple. The MT-G2 really needs to be run on 2 cells to get the voltage it needs.
2xRCR or 14500 simply won’t give yo much runtime as they will be offering only 700mAh or so. You could build a fun light like this, but 10 mins or so is all it’ll offer, so it’ll have no actual practical use.
Which means you really are limited to 2x18650. The most common configuration is end on end, making for a longer light.
There are some torches that have the batteries side by side, but your options are limited. And such torches would IMO not be overly pocket friendly as an EDC.
If you are happy to look at other emitters then you’ll have a wider choice of body styles and shapes to consider and battery types. But if you want to stick with the MT-G2 then you will have to compromise elsewhere and most likely in physical size and runtime.
The Solarforce K3 would seem to be the obvious choice on a budget. Running it on a standard L2 body with 2xRCR (or 2x18350) will make it compact, but runtime will be very low. You really need the body extender to run 2x18650 if you want any kind of decent runtimes.
e.g.
L2 with 2xRCR = 8.4v and 700mAh
L2 extender with 2x18650 = 8.4v and 3400mAh
That’s almost a 5 fold increase in runtime.
That all said and done, I’m not convinced the K3 will offer the flood you are after. But I’ll answer that in my next post.
I think a common issue on here and in general when talking lights is what people actually mean by things such as “flood” or “throw”.
For instance, with a normal reflector you have two main parts to the beam; the hotspot and the spill.
The size of the hotspot is really determined by the size of the LED, e.g. using the same reflector an XM-L2 will have a larger hot spot than an XP-G2 because the XM-L2 is physically larger.
This is then closely related to throw, in that a wider reflector and especially in relation to the LED size will mean more throw. e.g.
-The same emitter (XM-L2) in a small 10mm reflector will offer very little throw and will be far more floody than the XM-L2 in a 50mm reflector.
-Or different emitters, such as an XM-L2 and an XP-G2 both in a 30mm reflector, the XP-G2 will have more throw.
Spill has IMO two main attributes, it’s size/diameter and it’s brightness.
Reflector depth (and bezel) can affect how big the diameter of the spill is, e.g. a shallow reflector will mean a wider spill area.
But more lumen output will mean a brighter spill.
Next up is the transition between hotspot and spill, this has several affects such as the visual impact and the contrast between spill and hotspot.
A SMO reflector will as a rule offer maximum throw and lumens (OTF) compared to an OP reflector.
SMO - should be a very crisp well defined hotspot with a very clear cut drop in brightness for the spill. The complete opposite of gradual.
OP - the hot spot should have a very undefined edge and the transition from hotspot to spill will be far more defused and blended. This gives the visual impact of a more even light/luminance and can make the spill look brighter. As you travel further out from the hotspot the spill will gradually get dimmer. The downside of getting this more even beam is slightly less lumens OFT and less throw.
Adding a diffuser does exactly that, it will defuse the light to be far more even (often used in photography). But diffusing the light will dramatically reduce OTF lumens and have a massive affect on throw/beam distance.
The reason I say all this, is depending on what you actually want and want to use it for, will have a big affect on what approach to take.
To get the most even light output will mean your beam distance will be very limited.
Getting a larger hotspot to light up a wider area but still retain some throw characteristics to the beam will be a very different light.
Or is it just about transition from hot spot to spill?
Theres lots of pictures here of different leds. lf you have any questions feel free to ask. DeDo is my abbreviation of dedomed.
Not necessarily. A good diffuser only reduces OTF lumens by like 3% or 5%, which is a small enough difference that it’s not really perceptible.
However, it does make the hotspot and throw dramatically less intense.
