FS: MT-G2 Mag Mod with Voltage Monitor Option...

[jayrob]

Wow! These MT-G2 emitters are a bit floody but dang!

Over 2000 lumens at 3 Amps per this testing shown here!
(Shown, is a 3 Amp, 3 mode buck driver with 2 X 6000mAh 32650 Li-Ion cells - not over driving the emitter)

My personal build is using 5 Amps... (see 5 Amp option below)







Build Details:

* 2D Mag (let me know your color choice)
* MT-G2 6V 5000K emitter on copper sink pad set on custom heatsink as shown
* Copper heatsink option
* 3 Amp, 3 mode buck driver - L,M,H w/memory (see current readings below)
* Or 5 Amp Qlite MT-G2 Zener mod - L,M,H w/memory (see current readings below)
* Aluminum reflector (specify smooth or MOP)
* UCL glass lens
* Fine focus adjustment
* Voltage monitor option

The aluminum reflector is machined to fit the 20mm copper sink pad and heatsink post...








Beam comparison: XML-2 vs MT-G2:

Voltage monitor option:

Battery voltage monitor color code:

Bright blue - Full charge
Cyan - Very good
Green - Good
Yellow/Amber - Low warning
Red - Batteries low


The Spectrum battery voltage monitor will have a short 2 second initialization and some flashing when you first turn on the light. This is normal...









Current readings with 3 Amp driver: (High/medium/low)

Measured at the emitter:
* High - 3200mA's
* Medium - 989mA's
* Low - 185mA's


Measured at the tail: (battery current draw from 2 X 32650 Li-Ion's)
* High - 3300mA's... Estimated run time - About 1.8 hours.
* Medium - 1 Amp... Estimated run time - About 6 hours.
* Low - 200mA's - Estimated run time - About 30 hours.


That's using 6000mAh capacity 32650's...







5 Amp option:

I've got a good option for a 3 mode 5 Amp set up using 2 cells with voltage monitor option!

I'm using the Qlite MT-G2 Zener mod driver. For my personal build, I ordered the driver with 5 extra chips for a total of 13 380mA chips giving about 5 Amps... (if you want 11 chips total, it would be about 4 Amps)

As shown in the pictures below, the driver has brass rings soldered on for help with the heat management, and then I used Arctic Alumina thermal adhesive to pot the chips.

Then when installing, I use more Arctic Alumina thermal adhesive to fill all air gaps in the heatsink driver cavity as the driver is 'squeezed it into place'.

Current readings with 5 Amp driver: (High/medium/low)

This is a linear driver, so the current to the emitter is pretty much the same as measured at the tail...

Measured at the emitter:
* High - 4790mA's
* Medium - 1115mA's
* Low - 85mA's

Measured at the tail: (battery current draw from 2 X 32650 Li-Ion's)
* High - 4790mA's... Estimated run time - About 1.25 hours.
* Medium - 1355mA"s... Estimated run time - About 4.4 hours.
* Low - 108mA's - Estimated run time - Over 50 hours.

That's using 6000mAh capacity 32650's..

Note: This emitter at 5 Amps is 30 Watts. You must use common sense with your run times for this build. (in High mode) If it gets too warm in your hand, you will get a sense of the proper duty for your run time...

Pricing for the custom driver and extra work on a 5 Amp build (or 4 Amp) - Add $30






Pricing With Options:

The complete MT-G2 Maglite build will include:

* 2D Maglite host (your choice of color)
* MT-G2 6V 5000K emitter on copper sink pad set on aluminum heatsink
* 3 Amp, 3 mode buck driver - L,M,H, w/memory
* Aluminum reflector (specify smooth or MOP)
* UCL glass lens

$189

Options:

* 5 Amp (or 4 Amp) driver option (L,M,H, w/memory) - $30
* Copper heatsink option - $28
* Spectrum battery monitor installed - $58 The price of the Spectrum board is over $30 bucks, and my price for the installation as shown, is an additional $23 dollars. (this is actually more time consuming than it's worth to me, but it's so cool, that I'm trying to make it affordable)
* 6000mAh 32650 cells - $24 each (I have protected or non-protected - same price / tail cap mod needed for protected cells)
* WF-188 charger - $29
* Tail cap mod (if using protected cells) - $15

* Shipping will be based on a handling fee plus postage. (send PM for total)


Hope you like it!

Wow these look great I need a new flashlight for the scouts, but i'm on a budget ��

If I had the money I would snatch one of these in a second!

Great job as usual.

They are quite floody indeed.
I threw one in a convoy m1 at 4.4a Lmao (5.5" host)
Thing is a mini monster! Gets pretty hot too. :eg:

Also have a dedomed mtg2 in the Mx25l3vn. 3000lm. This thing lights up everything in a 100m area. Not the best thrower, but for practical use, if you're not illuminating hundreds of yards away, you can't get much better. You can see everything when this led is used correctly awesome build.

Great features including good heat management with my custom heatsink in a Mag size...

Plus fine focus ability, and great battery capacity!

Not to mention the cool voltage monitor option...

I think you'll like it! :beer:

Here's some recent feedback quoted from Candle Power Forums: (3 Amp build)

Got my MT-G2 Mag Mod from Jayrob last week and am very happy! The light works great and met all my expectations. Communication with Jayrob was quick and he was very patient answering my questions, even when I changed my order a couple times. I would definitely do business with him again!

The light came well packaged in it's original packaging. All stock mag parts were included and came with a sheet explaining the features and instructions.



The light worked great out of the box. The two 32650's were equally charged and the voltage monitor works beautifully and sits flush with the Maglite body. On high the light gets warm but not too hot after 10-15 minutes. On medium and low the light remains cool through the entire runtime. I haven't been able to test the full runtimes of each mode, but the battery drain rate seems to be on par with the runtime data in Jayrob's first post.

This Mag puts out a wall of light! I work in EMS and find that floodier lights are much more useful for my job, and I usually utilize my lights for short to medium distances. But even with the huge floody emitter, the sheer power of the MT-G2 puts out decent throw with the smooth aluminum reflector. It is a powerhouse in an inconspicuous package.

My other light is a Fenix TK45 so I was able to compare the two.



The TK45 is rated at 760 lumens. The MT-G2 is estimated to put out over 2000 lumens at 3 amps. You can see the ability of the MT-G2 to light up a room much better than the TK45 and with a much more neutral tint. These are my first light comparison shots. Both photos were taken at f8 1/45 for comparison's sake which doesn't quite give justice to the sheer amount of light either one puts out.

TK45 on High. f8 1/45


MT-G2 on High. f8 1/45


Both MT-G2 and TK45 have floodier beam profiles. While the MT-G2 retains the ability to fine focus the beam, it is still relatively floody, and the spill is able to light up the immediate area very well.

TK45 on High. Tree is about 25 yards away. f8 1/4


MT-G2 on High. f8 1/4


And these last two shots show the tint. The neutral tint of the MT-G2 is great. Both shots taken on auto setting. White wall was 5 feet away.

TK45 on High. f8 1/500


MT-G2 on High. f9.5 1/500


Overall I'm very happy with this Mod. If you're contemplating buying one you can be confident Jayrob will do good work!

Love good feedback...

Had to share this post from a buyer in Singapore: (Candle Power Forums)

Hi jayrob!
Received my light! I love it! MT-G2 driven at 5A is jaw-dropping, but coupled with the beauty of the 20mm star and emitter taking centre-stage, it is downright beautiful. Nice and clean modding work. Superb! :thumbsup:
I'll let the photo below do the talking...
