Better than that would be if they did to MT-G2 what they just did with XP-G2/E2. They came out with a “new” XP-E2 Torch emitter that has the same output as a XP-G2, but in a smaller die size. Maybe they could make a single-die MT-G2 equivalent output emitter in XM-L2 die size! I know they already have XHP-50 and XHP-70 but those are quad die.

Since we’re speculating wildly here Smile
I’d love a smaller or rather, a more tightly packed mt-g2 array die. That would be great, it’s all about minimizing those inter-die gaps.
But I think what we like so much about the mt-g2, primarily for me the nice even tint and decent output is mostly down to that multi-die raised array pattern of the emitter. I suspect a single die version the size of an XML would simply be an XML, if you get my drift?
I hope Cree will actually keep developing the MT-XX range and not just shift to quad die emitters to fill that requirement.

Ordered one even though I have no idea what to do with it (I have never had one before). Thanks Hank!

I’m sure you’ll find a use for it once you fire it up for the first time. They’re pretty special emitters. Smile

I’m sure you’re right! I just have a lot of research to do. I don’t know a lot about them and I am trying to find a host that’s not too hard to put together and is on the budget side of things.

I’m thinking of this one if it is still available. It looks like all I would need to do is grind down the 22mm FET driver from Mountain Electronics.

Lol, those are my exact plans (except slightly different driver). I guess I’m not very special

An XML that puts out the quantity and quality of light like an MTG is exactly what I’m talking about. I didn’t know the MT-G2 was a multi-die emitter. But, what I’m asking for is more light in a smaller die, like they did by making a “XP-E2 Torch” emitter that acts like a XP-G2 in a smaller size. I don’t really care if they do or don’t continue the MT-XX line itself, as long as the technology is improving. If they want to make a smaller MT-G2 and call it XM-L3, it won’t hurt my feelings.

Don’t bother to buy it.. I have one, it’s bad quality , go for Supfire L3 from RMM, much better light and host

Thanks Hank.

Unfortunately, I still have 2 bare emitters with which I have no plans.. So no meaning of buying any more.

Thanks for the great stuff!

So which host will the 20mm Noctigon MT-G and LD-2D driver (13mm tall/20mm od) fit into for 2 or 3 cell operation… 26650 preferred.

Since it’s such a good price, I wanna buy one…l haven’t really looked into these at all.

Can I go wrong with this one? Thinking about getting it for an aspheric. (Possibly an uf 1405)

CREE MT-G2 Q0 on Noctigon MT-G16 MCPCB
6V Version
Approximated light output:
920-970lumens 1100mA 25°C 2116-2232lumens 3000mA 25°C
Color temperature: 5000K

Thanks!

As long as you’re happy to have a zoomed in hotspot that looks like this…

…then go right ahead Smile

Am I ever! It looks like the future! At least what we pictured it as in the 80’s.

I figure with the 16mm I can play with it and try it in multiple lights.

hehe, it’s a great emitter. IMO best suited to flood type lights but if you like the look of the die projection you can certainly make it work in an aspheric. Other members here have put it in a Jax z1 and similar lights so if you search for that you’ll see what it can do.

A purely 6V single die version of the XHP would be sweet. I think the quad die might be a consequence of 6V/12V versatility.

Three Tanna leaves to give him life, nine to give him movement. But what if he eats the whole bag?

I always thought that a single die blue/white led has an inherent forward voltage of around 3v, and to get a higher voltage white led you have to string multiple dies together. e.g the 6v Mt-g2 is not a single die led but an array, xhp is a quad etc.
Maybe they could do something to minimize the gaps between multiple dies though, that would be good.

I’m just waiting and praying for an MT-G3, higher CRI, higher output, denser array pattern etc Smile

Right ON! And if I might add (praying wise) a 8.4v 26650 size battery too!!

Thankyou guy’s for sharing this deal I ordered onejust now and have one of these flashlight’s just sitting here waiting for this emmiter—>

http://www.tmart.com/TrustFire-SST-50-6W-1300-Lumen-5-Mode-Focus-LED-Flashlight-Black_p134350.html

I hope custom’s does not keep or hold onto this led like they have from my last order with Hank.

Hank was even nice enough to send another shipement of XM-L2’s and even it hasn’t made it here either and I think this is all on custom’s.

Iv’e ordered from Hank before and it went smooth and he even writes back when he can on advice when he does not have to so I do not want to deter anyone from ordering from him as like I said I just now ordered one of these MT-G2’s myself.

For those with no idea what to do with them, I’m thinking of making a lamp with one.

I have made 2 already, both with Squirrel cage incandescent lamps. Iirc, they were 2200k, what a beautiful golden glow they give off.

Here is a link to show what I mean.

https://www.etsy.com/uk/market/pipe_lamp

Pinterest also has some good ones.

I have looked very carefully at the ansi light charts and compaired the xml tints to the MT-G2 tints (for the P0 and Q0 5000K tints only) the 2 step “MTGBEZ-00-0000-0N00P050H” 70 CRI is centered right on the intersection of 3b-3c-3d-3a with a slight bias of 3B being the closest match (again on paper based on cree specs) YMMV.

I have also noticed that when I up binned my P0 to Q0 “good” lights I used one of the leftover P0 MT-G2 emitters but drove it DD and it is now in fact “whiter/cooler” then the “higher” binned Q0. My point being that the “coolness” of the MT-G2 is also a function of how hard it is bing driven.

Yes good observation, that’s certainly an aspect of these leds and actually well documented in the datasheet under “Relative Chromaticity vs Current”, and “Relative Chromaticity vs Temperature”.
Essentially the harder and hotter you drive the emitter the more the temperature and tint will shift from it’s binned state.

In general the light tends to get cooler in terms of colour temperature and shifts towards the pinker side of the chromaticity spectrum as the led is driven harder.

It’s also a reason I generally don’t like truly current controlled drivers vs PWM controlled ones. With the current controlled scenario the emitters tend to look considerably greener and warmer in the lower modes and turn bluer/whiter as the modes are stepped through. Not pretty.

PWM mode control is always a pulsed form of maximum drive current so there is essentially no difference in how hard you drive the led, simply a difference in how long the on pulses last. (of course temperature still affects the tint shift here)

If it gets noticeably blue and you start to see a separation between blue and yellow in the hotspot you should take that as a hint that you’re driving the emitter beyond it’s capabilities thermally.

Not sure about other Crees but the XML2 is supposed to shift warmer as temps go up and cooler (tint) as current increases. If it turns bluer due to heat, it’s probably at the point of failure. I don’t see anything in the MTG2 data sheet that indicates a shift one way or the other which would be nice.

I have one running on only 5v USB right now and it makes a nice keyboard light. Smile I’m waiting on an extension tube for my C12 before I can see what it’ll really do. Evil
