Are all MT-G2 lights going to be somewhat floody?

LED Flashlights – General Info
1

Hi,

I bought an MT-G2 flashlight from a builder on “the other forum”, and just received it yesterday. I had a chance to try it out last night, with 2 new, fully-charged Efest IMR 18650s, and, as expected, it was super bright. Tailcap current was about 3.3+ amps.

I also had my new HD2010 from Tmart and was comparing the new MT-G2 light with the HD2010 (with the same Efest IMR battery; tailcap current ~4 amps) in my backyard, where we have a line of trees just short of ~50 yards.

From that, the beam from the MT-G2 light was super floody, lighting up almost the entire area, but while it did light up the line of trees somewhat, it wasn’t much, and, at distance, there really wasn’t what I’d call a hotspot.

Of course, the HD2010 easily lit up those same trees, and much brighter, with a very discernable, and bright hotspot.

So, I was wondering, is that kind of performance (mostly flood) going to be typical of all MT-G2 flashlights, like the Crelant and the SolarForce?

Thanks,
Jim

Yes, in traditional sized lights its going to be way floodier. The MTG2 is more like the sst90 in size and if you look at SSt90 throwers they are quite large in comparison.

I think MTG2 could make a great thrower, but it’ll have to be in a head larger and deeper than the Olight SR90. In anything smaller its not going to be able to compete with an xml2 for throw

Hi,

What about the new lights that are coming out with MT-G2, like the SolarForce, Crelant, and Niwalker. Do they have heads designed such that those lights are “good throwers”? I have read through the threads, but haven’t seen something that says exactly… maybe because it’s always not going to be an “apples vs. apples” type comparison, i.e., no single light with models with both MT-G2 and, say, XM-L2?

Without a huge reflector, the MTG2 has to be floody.

Nitecore EA8W... (Probably XMLT6)

EA8 Modded with MTG2 running at 3A

EA8 MTG2

The larger reflector of the Crelant 7G10 does mean it has decent throw, but it's still not really a "thrower" light.

For real life use purposes, I think the MTG2 lights will be a great hit... yes they won't put a dot of light on something 300 meters away, but they will work to light up the 100 meters in front of you beautifully.

I'm really hoping we see an EDC sized MTG2 light soon.

Man infinitusequitas, if you ever decide to sell that modded EA8 I will gladly take it off your hands.

Yes, the MT-G2 is the flood king of emitters but with a nice tint. I just don't see a thrower in the future for the emitter, and don't know of anyone anywhere posting or claiming anything about it's throw ability in any host so far. Talk is a designed reflector for it would throw, but dunno - seems it can't compete against a good XM-L2. If you did have a monster reflector for it, well, an XM-L2 in that reflector would throw better anyway.

I was thinking of putting one in my resistor mod'ed TN31, but currently it's got a de-domed XM-L2 U2 doing close to 350 kcd which is a pretty skinny beam - a de-domed XP-G2 is even a smaller beam. I would expect the MT-G2 to have a definite wider beam specially with the dome (de-doming these didn't seem to work out), but then the resulting throw would drop a whole bunch, just not sure how much, but bet I'd be lucky to get 100 kcd out of it.

The 7g10 won’t throw like the 7G9. A good example is the Foursevens S12, it has an sst90 and doesn’t throw near as far as the XML counterpart the X10<(I think that’s what it was called)

The Crelant and Solarforce MTG2 lights, if I had to guess will throw as far or a lil farther than an HD2010, and be floodier. Don’t buy em if you want a thrower

I think even with a huge reflector, the MT-G2 is going to be floody. All you have to do is look at the die face to realize it's designed to flood, not to throw. With all of the little pyramids (raised surfaces), on the face of the die, it is supposed to put light out in all directions and flood an area evenly. I do not see Cree or anyone else looking to make another 90 degree led specifically for flashlights, when the market is in industrial and commercial lighting. I think there will be more powerful leds that come out, but I bet they will not be great for throwers.

The larger the die size, the bigger the spot, no matter what reflector you have.

That's my story, right or wrong...Undecided and I'm stickin to it for the next 30 seconds.

I actually like mt-g2 torchlite, at 100+ yards the hotspot takes in two english terraced houses lol.

It’s never going to be the last word in throwers imo but it does give a lovely subtle usable light for going on a walkabout.

+1 -- Definitely a practical emitter. That's why I'm thinking in a TN31 host at 5 amps it would have a nice, wide swarth of a center beam, but measured, can't compare in raw distance.

Not a chance. This one is definitely a keeper :p

In the Defiant xml spotlight (92mm reflector), my dedomed mgt2 throws very well. I have nothing that out throws it. The spill is fairly faint. Probably similar to the spill of an HD2010, but bigger in diameter. I have no spot on my property that I can not light up in a big way from any other spot on my property. 14 acres, but the longest clear line of sight I have is about 600 - 800 feet.

infinitusequitas,

I’ve been following a thread on the other forum, where a guy (or, at least I assume that the user’s a guy) has been taking pre-orders for what appear to be some EDC-able MT-G2 lights. Right now, it looks like he’s getting close, and I think will be offering 2 different hosts, a Convoy M2 or a “T10”.

Here’s the link to his thread:

He said that the lights will run on 2x18350s.

Ohaya, we need more info than 'an MTG2 light'. What size reflector? Is it properly focused? Is the builder aware of the unique focus requirements for this particular LED?

MTG2 in a 72x72mm reflector is far from 'floody', when compared to other lights people routinely praise - like a SRK. Now THAT is a flooder. In a good reflector a MTG2 is nothing like a SRK, so please don't slap the 'it's a flooder LED' label on this thing.

It's only 'floody' if your baseline is a tiny little XR-E w/aspheric, or something.

In a Lena reflector from ledil, the mtg2 throws about 400m+. It’s slightly deceptive because everything between you and the target is also illuminated. It’s not your average thrower…its better!

Hot spot? Nah, hot area!

16

Yes, and you can even identify the thing you're aiming at +/-300m away, rather than projecting a little square postage stamp onto something you can't see enough of to tell what it is. :p

17

Hi,

I didn’t “slap” anything… it was, after all, a question :)… Plus, did I even mention an SRK in the OP?

This is the light I got:

Are there any lights that use that reflector?

Well put comfy. I wonder how the mgt2 would work in a typical sized reflector flashlight that has a very tight beam. Like the Maglite D and C LED reflectors. The Defiant Super Thrower has a semi tight beam.

By the way, nice beam shots infinitusequitas. Thank you for sharing. :slight_smile:

Edit: I wouldn’t recommend dedoming the MGT2. The phosphor comes off quite easily. I feel I was lucky. If someone does want to, I think using the heat of the led to perform the dedome would probably be the best approach.

Think of it as somewhere between multi-XML lights and dedicated XM-L throwers. (maybe leaning towards the throw performance side)

And for multi MT-G2 lights, the batteries/drivers would be the limiting factor, unless you put them into a pretty large host. ie larger than say a typical 100mm head diameter light.
