I finally found a nice purpose for my poor MTG2 that I got about 2 weeks ago,which has been slated for a mod but I haven't had time.I love the small sun zy-t13 and I was searching for a suitable reflector for the MTG2,where I didn't have to mess around too much,found it to be a perfect fit.I had tested the MTG2 in a various reflectors I had even the TN-31 and I have to say in order to get some decent throw from it,you will need to use a huge reflector.The board was put down on arctic alumina and as some probably know,the zy-t13 heatsink is not really that adequate and the light now heats up very quick.I can only describe the beam as a big thick column of light like the TN-31,with the 5000k being a very pleasing color.Amps at the tailcap are reading 1.98,so essentially 4 amps draw from the 2 cells which are redilast 3100's.The beamshots on the white door are modded zy-t13 on the left and solarforce hybrid mod on the right and that mod used the ultrafire drop-in @ 4 amps.The solarforce mod is super bright,and as you can tell,the modded zy-t13 just smashes it.Outdoor shots were done on my cell phone camera and set at iso 400 and about 75 feet to the top of the tree.There was lots of ambient light and snow in the pictures so to describe what I see with my eyes,I would say the light is much brighter than what the pictures show.I have a much larger host and a different driver in mind for my next MTG2 mod,this is just a start for my experiments with MTG2.I am a big fan of throw and I plan to make a thrower out of this led soon,and I have to say the MTG2 just crushes the erstwhile emitter in the zy-t13.Thanks for putting up with my rambling and hopefully this demonstrates the potential of this emitter.

Nice! Hmm...I happen to have a spare T13 host laying about unused, too.
I’m liking that it fits in an xm-l reflector.
I think the torchlite host that’s on the way will definitely end up with an mt-g2, has anyone tried the warm white yet? Because given cutters shipping, I was going to order a few things at once.
Good job darcangel it looks like this won’t be all that difficult to fit into a two cell host, biggest difficulty will lie in finding a big enough reflector as I’m not an aspheric fan at all.

Nice mod darcangel. I can put up with that sort of rambling all day. What driver did you use as I thought these had a different voltage requirement th the XM-L?

thanks for the info
i think this mod, and the other mods we’ll see over the next couple months, will put to rest the claims of a few people that this emitter isn’t good for flashlights LOL
Awesome mod! 8)
PLEASE MORE DETAILS AND PICS!
What driver did you use?
Did you have to modify the reflector in any way?
Where did you purchase your MTG2? Link?
I am thinking in getting one and glue it to a computer heatsink then stuff it inside a spotlight. Is that what you had in mind?
Congrats on your succesful build!
I agree, I’m wondering if the family can go without food for a week to cover the bits I
needwant. :bigsmile:Alex gt, check the edc+ 26650 host thread…..

Thanks gords for refering me to that thread here

I wonder how that 5A multi emitter driver discussed there will perform with the MTG2 led
Driver

I think I’ll probably order one soon to experiment with it
we’re going to find out! they’ve both shipped and need only arrive at my door :bigsmile:
I’ve just realised I’m giving up smoking, that’ll pay for the driver and mt-g2, I’m still going to wait though as I want to order some xp-g2’s and xm-l2’s as well.

Hmm - how about the Defiant Spotlight for a host? kramer5150's build thread here.

i think that’s the best candidate based on reflector
but I think the stanley fatmax might be an easier mod
Both these spotlights seem to be good size and would be perfect for the MTG2's huge die size.Now look what I started
imagine when some manufacturers get in on this and DESIGN a reflector for it :bigsmile:
Yes, interesting, one other above requested a link to the source for the MT-G2 source — I, too, would like to know it, please…
Flomotion
I have ordered several and will have at least one extra. Shipping for one, or several, to NY was $13 plus about $2.5 ‘handling’…

You can isolate the led wires using kapton tape, it is very thin and can withstand high temperatures, I wish I had known of the group buy of MTG2’s I would have jumped in too.
there wasn’t really a group buy, i just ordered more than i need
so you just did, sort of
there is one on its way that is unspoken for – IF I don’t poof one when I test w/ this driver

This led could work really good with the Trustfire X7 SST-50, has a huge reflector and beefier heatsink… Might jus build it!
What is the biggest led reflector light out there?
I am interested if you decide to sell, let me know
Check out the “Lena” reflector it has an 11 degree beam, 111 × 87 mm and a 14mm hole for the led, looks promising!

I’m still doing research for something bigger so I can put it in a regular spotlight, going to check on aliexpress…
did you check out the defiant linked above?
i think it is 92mm reflector, and $25 at home depot.
looks like DX sold out of this. overpriced anyway, but maybe available elsewhere

here’s a couple candidates

There was talk of a smooth 128 mm diameter x 120 mm deep reflector in one of the ST90 threads.

Little more to compare with on top is the sky ray king and bottom MTG2 modded zy-t13,king is brighter but not by much.King is cool white just to clarify,shots were taken at 10 feet from the wall and 30 seconds elapsed time.I also went further and measured amps at the emitter and got between 3.2 and 3.4 amps,which lends credibility to match's figure of about 2000 lumens.That seems accurate as the king is around 2300 lumens and to my eye,there's not much difference.Heat is definitely the enemy here,I timed the visual evidence of thermal sag at about 4min.19sec. where it dropped in output considerably.The middle of the light was hot but not to the point of unable to hold,so right off I can say a copper pill and a more robust host is needed to handle the heat created.I love this light more than ever now but I realize the inability to handle the heat makes impractical for over 5 minutes of use.
nice pic!
in most situations where I’d use a flashlight with that much output and throw, I’d probably be moving enough to help with cooling, at least a little.
Now that is an interesting reflector, quoted as having a 4 degree beam!
