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
- 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)
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 custom heatsink as shown
- 3 Amp, 3 mode buck driver - L,M,H w/memory
- Aluminum reflector (specify smooth or MOP)
