Convoy L6... XHP70 Beast!

I have quite a few XHP70 lights and with pretty much every Bin and tint, and shaved and non shaved, and I can’t think of one that I have that would or could compare to a MTG-2? To me the MTG-2 is the King of Neutral Beauty! So define Neutral White? The supposedly neutral XHP70’s out there are usually lower bin and lower out put, and in a OP reflector just seem kinda blah? That’s why I like the smooth reflector, and my emitters shaved of the higher bin, more throw and tends to warm them up a bit, but nothing close to a MTG-2? So I guess throw a MTG-2 in it??

The 96 CRI XHP-70 in my Intimidator way outperforms an MT-G2 and is just as pretty or more so. But I still highly favor my 10 or 11 MT-G2 lights and my triple 9V MT-G2 BTU Shocker is a personal favorite.

So yeah, I think the L6 with an MT-G2 would be freaking awesome! (The L2 is, so why not?)

Dale dome on right? I shaved the same one down and it’s in one of my SD75’s, in the case sitting on the shelf! I didn’t like it much out of the OP reflector, but then again the SD75 Op reflector was not half as good as the Crelant 7G10 or the S70 quality wise! But I live in the city so I need brute force to compete with all the street lights and all the ambient lighting that’s around, it never really gets dark out where I live? :smiley: I have to be able to see whats in their hands not how vivid the color of the clothes look at night? :wink: Just kidding! :smiley: I really need to move out to the country, meh some day!

Yeah, big difference competing with all the ambient. I need to see if it’s a grey fox looking to eat barn cats or Redd Foxx looking to steal my junk! :stuck_out_tongue: lol

My High CRI variant is surrounded by the LUM 5-90, excellent reflector.

Edit: I don’t shave the domes on these as they’re simply not throwers to begin with. I did shave the 4 XHP-50’s I put in a D80 but that was to fit em under the Quad optic…

See that’s a big part too, a quality reflector is the heart of any light, you can change drivers and emitters to the cow’s come home, if you have a crap reflector, it’s just a waste of money! Thank God I weaseled out a couple smooth reflectors from Lumintop, before they shut it down!! :wink:

Yes, yes, yes!

I love the MT-G2, but too often, the one used in flashlights has a CRI of 70 Ra. On the Cree datasheet, I saw an MT-G2 with a CCT of 5000K and CRI of 80 Ra, but I have never seen it in a flashlight.

I was thinking last night about the option of an MT-G2 if a good NW xhp70 could not be sourced.

Can a MT-G2 be driven as hard as an xhp70?

I don’t know that I’m as interested in a MT-G2 version, but that’s because I already have an Eagletac MX25L3 that I love.

The MT-G2 can do over 16A. But it’s only making some 4300-4500 lumens up there and has started dropping in output after 12A. Djozz has charts on all that, I find them to be very accurate to what I see in an actual light.
The XHP-70, being essentially a Quad XM-L2, makes more output on lower amperage and I’ve seen it doing some 12A or more with very high output, and accompanying heat factor as well.

The MT-G2 is available in 80CRI and 90CRI variants, at a cost of lumens. Even at a measely 1.1A, lumens drop is over 300. And the CRI 90 is at 3000K, very warm.

There is a 9V MT-G2 available that can run on 3 18650’s (or 3 26650’s as the case may be) and it makes more output, around 4900 lumens up in the high range, which is getting close to the High CRI XHP-70. I think my SR-90 is making just over 5000 lumens from rested and partially used cells.

Good info, thanks.

Wow never knew that about a 12v MT-G2! What about a 12v XHP70 Dale?

How do i make a thread here? i’m not quite sure how.

9V MT-G2, they come in 6V, 9V, and 36V variations.

The 12V XHP-70 requires a specialized mcpcb that has the dies in 2S2P arrangement. It’s the same die, just wired differently on the mcpcb. The 6V XHP-70 mcpcb looks pretty much like any other star with long electrical connections on either side of the thermal pad. The 12V XHP-70 mcpcb has short sections on each side and has jumper pads in order to wire the 4 dies differently. I don’t like that one because the traces all seem very skinny, but I guess it takes lower current at higher voltage so perhaps it’s all the same?

Yeah, I understand that part about the 12v XHP70 but what about out put? I like the idea of higher voltage lower current, higher out put like you described about the MT-G2 like 900 lumens more, but would you get that or more out of a 12v XHP70? Say 1000-1200 lumens or more? Because some claim 6000 lumens out of a hard driven 6v (8,4) XHP70, so could it be possible 7000-7200 lumens out of a 12v XHP70?

Well, I saw some 6400 in my Intimidator when I first built it, with a 6V on a 6V star and running FET direct drive Zener modded. I opted for the High CRI at 96 because of that color renditioning. I don’t use the light a lot, actually had it as a mile thrower with a de-domed XM-L2 to start with. Can’t see a mile at night, so I put in the XHP-70 for giggles and grins, then switched to the Hi CRI.

I don’t know that the 12V set-up would net that much gain, it might, but I don’t recall. It’d be pushing the envelope for sure, but hey, it’s what we do right? :stuck_out_tongue:

6V vs 12V SinkPAD mcpcb

Edit: Well DUH! That’s an XHP-70 and XHP-50 but it shows how they get 12V out of the same die.

In the 9V variant of MT-G2, the mcpcb is the same either way.

+1

as a reckless data point. I have an experimental light 3s using 3x14500 that I use direct drive to drive a 6v xhp70. works like a champ. the emitter can take it. or maybe using wimpy 14500 has enough voltage drop that it is still safe from turning angry blue.

So for all those interested (including myself) I am talking to Simon about making accommodations for the MT-G2 at least in the host form. Personally I’d love to see a clear anodized L6 with a nice neutral MT-G2. One step at a time though. Let’s get some of the L6 out there and start tinkering before we decide where this journey should go next.

Woohoo! This is gonna be EPIC! :slight_smile:
