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! :slight_smile:

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)
  • UCL glass lens

$189

Options:

  • 5 Amp (or 4 Amp) driver option (L,M,H w/memory) - $30
  • 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 - $22 each (I have protected or non-protected - same price / tail cap mod needed for protected cells)
  • 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!

Buyer Feedback…

Wow, thanks for offering!! Like the voltage monitor.

3

Lots of great feedback on the voltage monitor linked at the bottom of the OP… :slight_smile:

4

Wow, just WOW, $277 for MT-G2 Maglite with fancy battery indicator.
P.S. people here don’t like hate potted stuff…

5

Is there someone else on BLF offering a better price on made-to-order MT-G2 Maglites? Potted drivers are only a problem if you decide to mess with them. If everything is solid to start with, potting just makes the setup more solid.

6

O-L does sometimes, without the voltage meter tho, but for much less $.

7

OL is the mastemind for Maglite modification, if I recall correctly he had something similar (without battery indicator) for ~$130 but I may be mistaken it was long time ago…

8

Exactly. OL briefly offered made to order lights for $175 with no voltage monitoring option, prepay only, plastic reflector, ~1/8in HS IIRC, momentary-only (that driver drains Li-Ions in a matter of days…). OL’s offering had some good advantages for those who wanted it… file work, 3A to 9A option at build, LED Maglite reflector… but he threw the towel in not long after putting that offering up. Jayrob has been doing this for a while and I assume can be relied upon to still have the offering open if/when you become ready to order?

Jayrob’s price of $189 is comparable to OL’s price of $175. Their materials costs are also fairly close (LED mag vs incan mag, free plastic reflector vs aluminum KD one, coated glass vs UCL). Jayrob also offers several options (at added cost) which OL did not. And, again… jayrob is actually selling these now, not ‘sometimes’ or ‘previously’!

9

nice work. I like the battery monitor option.

10

This is where you post your own thread offering this type of light for sale at a much lower price. I look forward to seeing it. :slight_smile:

11

Tbh, you must be a magthusiast to buy something like this for 277$, for that price you get…… many other, better lights.

12

Yes thank you for mentioning that it is $189 (not $277)

And that $189 includes the aluminum reflector and UCL glass lens.

Many people already have Li-Ion cells. Voltage monitor is also an option…

13

The point isn’t that you can get something better somewhere else, or even whether you see the value in something like this yourself.
This is a custom light configured and hand built to order, the point is that for a custom light like this no there isn’t a better priced alternative available. Certainly not at the moment, unless of course you offer to build one and sell it at a better price yourself. If you’ve ever built a custom light you’ll know how even simple mods can quickly ecclipse the cost of the original light, and that’s before we even mention the work involved.

Maybe there is a massive untapped market of magthusiasts just itching for something like this, only jayrob could tell you if that’s the case or not. :slight_smile:

I stopped doing them because they don't sell well. Only a couple of people buy, unless you sell at CPF and are a long term CPF click member, which I am not. It's really not worth the time to make them and it is very expensive, unless you have available capital to buy a bunch of components at one time and you can sit on that stock till something sells. The "Plastic" reflector is still the best reflector for throw, in a Maglite, (as far as I am concerned) and it's usually in better condition than the overseas ones. The only reason I ever went with file work, was because that was the only thing that set me apart from the CPF members, who own the Maglite concession, so I just found a different way. They are fairly expensive to mod and jayrob, nor anyone else is getting rich on making them. It's mostly for fun, so enjoy them while they are available.

Sincere Good luck to Jayrob and his mods. I am sure they are well done. I have no doubt of that and I wish him well in his sales.

15

I don’t blame you OL! I tried to make my post sound equitable, I didn’t want it to come off as criticism of you so much as criticism of those comparing your past pricing with jayrob’s current pricing.

I think your offering was a good one, plenty fairly priced, and definitely a slightly different thing than what jayrob offers - that’s why I listed the benefits of your listing too. Nothing wrong with either product. I know you’ve had trouble selling lights. I understand why you wouldn’t want to offer a service like that on a long term basis with the possibility of a handful of sales just clobbering you out of the blue at some point (after months of nothing or whatever).

I just get frustrated when other people use your pricing as leverage. You make it clear that you don’t earn any money, you make it clear that your work is available when you say it is and not at other people’s whim… etc.

16

Jayrob’s being modest here. He had some of his modded lights in Night at the Museum. Maybe he can comment on it. I love stories like that.

17

“jayrob, nor anyone else is getting rich on making them”

Yes that’s true…

I make a little on them, but mostly it’s the enjoyment of building.

Thanks for mentioning that! Yes let me comment on Night at the Museum… :slight_smile:

So the prop master for the movie (Night at the Museum 3 - just released December 2014) contacted me because he saw my Vintage 1930’s Eveready mods shown at LPF, but I’ll post the thread here now… Vintage 1930’s Eveready mods shown here…

So they ended up getting three of those, and three custom Mag mods as well. (in 3D length for the movie)

Kind of cool watching the movie and seeing the lights in it… :slight_smile:

The Vintage Eveready shows up early in the movie when the boy falls into a tomb and pulls out his flashlight…

18

That’s really cool! Congrats :slight_smile:

And you’re lucky they didn’t replace them in post just for a few product placement dollars. I’d have been worried going to the cinema knowing what I know about the film post business :wink:
Suddenly you see a couple of new Nitecore flashlights where your lights would have been, haha.

19

Yeah they wanted to fly me out to London for the premier but I was too busy at work… (jk)

I was hoping that maybe there would be out takes for Ben Stiller and Owen Wilson arguing over who gets to keep the lights after the movie or something… lol

Because I know for sure that there must have been some talk about how cool the lights are. Especially the 1930’s Eveready mods…

20

Usually it’s the prop guys doing the arguing over the really cool stuff! :wink:
