I have seen so many modded lights with MT-G2 emitters, and many stock versions of popular lights built with the MT-G2 emitter. ( EX: Fenix TK35UE, Thrunite TN35, etc.) I have been trying to decide what my next mod with a MT-G2 will be, as i have a ton of capable lights that use two 18650s and have big reflectors to work with the big emitter.
that i thought about modding it to the MT-G2, and building a custom battery carrier to use 4 18650s, ( Dual-parallel in 2-series set up) but i also have various other lights i could use including a TK35 clone, several D Mags, etc.
I didn’t but I think Relic did one on his and that was where I got the idea from. It might have been comfy though I’m not sure.
I have done a bunch of them with different drivers. Runtime really depends on what driver you pick. I like using the old DRY driver but they are gone now. I have also used the Trustfire 3xT6 driver and that worked well too. The most output was a driver from a lustefire 3xu2. That one would pop the protection on two 3400 panasonics.
For good runtime and decent output the 3xT6 driver is a good choice.
As for the mod there really isn’t that much to it. The hardest part is modding the battery carrier to series and filing out the reflector to size.
It’s not that bad really, but you do need to turn it down after a few minuets. I generally only use the high as a turbo, say five minuets at a time max. But on a good long walk you can bounce back and forth and not have it heat up bad at all. I walk with mine quite a bit. Well right now I’m walking more with my maglite MT-G2 but it also has a ZY-T08 reflector in it. Great reflector for the MT-G2.
Ok have been looking for a cheap MTG2 host as I'm thinking of building one.
-good heat sinking
-least work possible
-doesn't focus the beam too much, preserves the floodyness.
$19 Dive light with twist on. Possibly less head material as water cooled. Weight unknown, head width 50mm.
$20 2013 Power Cree. 62mm head width 320g. There's an identical looking one called "Uniquefire UFF10B" that's $25 but is listed as 500g, considerably heavier but unsure of specification accuracy.
Lustefire D01. I think this is the Convoy L2 clone? 2 x 26650. $33. Weight and dimensions not listed. Looks to be lacking a little in head mass, but can't really fathom it from pictures alone.
And the trusty Trustfire 3T6 $23 . Unknown driver from this seller. Would it be a reflector + emitter swap and then good to go for 2 batteries? These are meant to have work-horse drivers but the lower modes have terrible PWM.
I have been currently working on several flashlights to run on MT-G2s:
Roche LS01 18650x2
Cheap Zoom 18650x2
Jax Z1 26650x2
SmallSun ZY-T08 18650x2
New 117 (TK35 clone) 18650x2
None of them can be considered a ‘finished’ product,
I keep modifying them, from time to time.
Now, a truly work in progress is the right most flashlight, XinTD X3.
At this moment, only the emitter is swapped, still thinking a suitable driver
for 14500x3 batts in series setup (should acommodate up to 12v).
Which one is really my favorite? Actually at this stage, I can’t really answer.
Perhaps I will know it after I have actually finished modding them,
which won’t happen in the near future.
Thanks! I like to compare ZY-T08 with New 117, because they have the same battery setup 18650x2 side by side.
T08’s reflector is quite good for MT-G2, I’m able to get a nice beam profile from it. With 117, the hotspot is less defined.
T08’s big head should somehow help to manage & disperse heat better, but will get in the way, if you’re thinking of carrying the light in your pocket. 117 is more pocketable.
The mass is there, you can feel that you are holding chunk of metal, instead of flimsy metal tube. Again, this is good for heat management. I believe 117 is lighter.
The only issue that I find with T08 is solder blobs (quick & clever hack to convert the battery setup from parallel to series) tend to leave scratch marks on the battery tips and its plastic cover. I’m still thinking of proper way to solve this issue. 117 has no problem about this, since its batteries are already in series.
All in all, ZY-T08 is a fairly good host, and decently priced too ($20). And… I just found out that you can get it as low as $16.57 at TMART with a free torchlight keychain! At least you know if you manage to break the T08 while modding it, you still have the torchlight keychain as backup (with only a few lumen less?)
