Hi, i have ongoing debate, with my stubborn friend, who claim that MT G2 would throw better if someone makes an ideal reflector (specially designed for it) compared to other reflector being specially designed for XM-L2.
He is very vocal about it, like “the most important thing is power, MT G2 pumps out much more lumens and therfore will outhrow the XM-L2” this are his words.
So what do you guys think, i think MT G2 stand no chance?
IDK man look at the olight throwers using the SST-90 and even MK-R, with enough time and money its more than possible to design a reflector to make the big emitters throw, then again you could take that same time and money and put it in a totally redesign reflector for an XM LED and probably get about the same results just less total lumen output.
What’d be really cool to see someone attempt would be an MT-G2 in one of the SR9x single emitter lights in the SST’s reflector (or even one of those SST-90 generic reflectors from KD).
XM-L2. It has been proven over and over with readings from light meters.
i have a spare MT-G2 kicking around, maybe i should give it a shot in my SR90. ( though i believe the stock Olight Driver is a bit to low voltage at the emitter, though i have not tested it really…
Well, I'm very interested as well..I just think the common reflectors are just not (good (big ) enough for the mt-g to really throw..nothing on the mainstream flashlight market has something big enough for an MTG, therefore I assume people think it doesn't throw.. current reflectors are max about 80mm?
How about a 150-200mm reflector, shaped for an MTG? Not sure if that won't throw..
Until someone really can prove it can't throw with a good reflector I'm still doubting it can't throw....
My recollection is throw is determined by surface brightness (lumens per square mm).
An LED may have a very small die, but a lot of lumens coming from that die…… so the surface brightness is higher.
All optics and reflectors work by taking the emitted light and projecting it into the distance. The higher the surface brightness, the brighter the spot in the distance.
Most large die emitters tend to have low surface brightness. They have more lumens due to more surface area… but the intensity of the light coming from any point on that die is lower.
An MTG2 probably won’t throw as well as an XML2, because the XML2’s surface brightness is higher. The MTG2 will emit more light and have a much wider spot, but the XML2 will have more lux and therefore more throw assuming both LEDS are placed in similar-sized optics or reflectors.
However, sometimes larger die emitters can outthrow smaller emitters. This typically happens when enough current can be put through them to increase their surface brightness beyond their smaller die cousins who can’t take as much current. I don’t know if the MTG2 falls into this category, but I doubt it.
Well, an XML need quite a bit of current to throw...more than an xpe can handle..So why not pump more amps in an MTG, and with a good reflector..who knows? Although, I'm not saying it will be a better thrower, just saying that if a light can throw over 80000-100000CD is a thrower for me...

Stock standard TN35 (MTG-2).
TN32 Stock standard. (XML-2).
I love the MTG-2 as a thrower and a all round light in the right reflector but it will not out throw an XML-2.
I have put an MT-G2 in a SST-90 and it still didn’t throw as far as a half way decent thrower. De-domed they are a little better but still not a thrower.
Throw comes from a combination of a few things. Diameter of the reflector and intensity of the emitter based on it’s size. So think about it this way. How many times bigger is a MT-G2 than a XM-L2? Maybe twenty times as big? At most it’s three times as many lumens as a XM-L2. So if you had a reflector that was seven times as big then you could get the same throw roughly speaking. But put an XM-L2 in that same size reflector and once again the XM-L2 will spank it. That’s just how it works.
There is an actual formula around someplace but I forget where. But that is how it works. This is also why an XP-G2 will out-throw an XM-L2 if it’s the same lumens in the same size reflector.
Of course there are some other small variables but that is the gist of it.
So no an MT-G2 Will not out-throw a XM-L2 given similar sized well constructed reflectors.
I dont think an mt g2 can beat an xml with intuition, but maybe later i will do some math to know for sure. That said with an appropriate quality reflector an mtg2 can be a very balanced light with decent throw and big lumen. My mtg2 throw around 130kcd and other say its in 150kcd range.
Would have to be a big-arse reflector for an mt-g2 to out throw an xml. The following mt-g2 is through a dx sst-90 reflector
It’s all about light emitted per mm² dye surface.
That’s what ultimately determines throw.

Sure it is about that but what are the values without overdrive ? Than come to play thermal resistance of emiter and with a lower resistance and a good cooling one led can overtake the other. Xpe2 verus xpg2 just show well this…
At factory values xml win for sure, in overdrive i still believe xml win but i have not the certainty math and numbers gave yet…
I wonder if the word "thrower" has changed its meaning?
When is a flashlight considered a thrower.
I think a few years back, around 2010, a light that threw about 50000cd wouldve be considered a thrower.. maybe since many lights can break the 100k barrier, the word "thrower" has changed its meaning?
So yes I think the mtg can definitely be called a thrower if it can do over 100kcd.
It won't outthrow an XML maybe, just like an XML can't outthrow an xpg or xpe.
Or does a thrower have to have a pencil beam??????
Some important questions I think.
I don't think we can't say a MTG can't be called a thrower because it can't outthrow an XML..I think that's a wrong conclusion...a thrower is a thrower.. but when can you call a light a thrower?
Reflector is the key. If both of ideal ones would have the same diameter, XM-L2 would outthrow MT-G2 easily. It’s quite common that people are confusing lumens and throw.
Like others have said. MT-G2 does not stand a chance vs XM-L2 in similar sized normal flashlight sized reflector when it comes to throw.
IMO a thrower is defined by its beam characteristic not by its kcd. This light can do 200-250kcd. Its still a flooder.
I think if reflector and led chip size match MT-G2 would throw better on same reflector surely xm-l
Very interesting answers, which i share the opinion with. Keep in mind, this guy is very strict, he say that he doesn’t care at all for using the same reflector, all he care is comparison with theoretical ideal reflectors made specially for this emitters, ideal for both leds.
So we talk about theoretical perfection for both lights.
So if a reflector was specifically made for the mt-g2 to throw like missile then the xml would easily adapt to that reflector and out throw it because of the lumen/die size ratio and beam pattern.
