Crelant 7G5MT - 2x18650 with MT-G2

Looks pretty good - 1860 Lumens @ 3.2A in a 7G5CS body with a variable output system.

i like that. wonder what it will go for

MD-Lightsource has them on the way but from what ive read on a few sites, including crelant, its only going to be a high & variable ramping mode light, well and the SOS & strobe. my guess is its going to be a good $100-150 for the light

Looks like a clone of the 7G5CS, just with upped amperage, and OP reflector.

Given the size of the LED, and the size of the reflector, it will be more of a flooder... the reflector is much smaller than on the 7G10 MTG2 light. Probably the reason they didn't put any throw information.

1860 in terms of lumens seems a tad low.

Biggest concern I would have with this light, is the relatively tiny size of the heatsink area... if it's they same exact size as on the 7G5CS, this light is likely to fry itself if left on.

Hopefully they'll get one out to someone for review. Personally, while I'm a crelant light fan, I think they screwed up big time with the 7G10, and I'll hold off on this one unless I see a positive review.

Anyone know of the collimator head will be compatible with this light? Might be interesting.

my 7g2cs was said to be high and ramping modes, but its ramping and ramping. i leave it set to low first then high

talked to mark yesterday so ill dig through my emails, but i think he said it would fit

The first generation of the 7G lights that had ramping, it always turned on, on high, when the tailcap was used, and from there you can use the side button to ramp the light to whatever output you like. After that so long as you don't use the tailcap switch it would remain at the same setting. Using the tailcap switch brought you right back to high.

The second generation, mostly that came out along with the xmlu2 LEDs, they added one more step, where the light starts on high, once turned on via tailcap. A second click of the side button brought the light into medium. Another click via side button turned it off. Either of the two steps, that are via side button, could be programmed, but the setting is lost once tailcap is used, and there is some parasitic drain.

Is your light set up by default to start in medium first and then high when you press the button, and this does not change after you use the tailcap switch?


thats mine.

i have a 7G5CS-U2 and it doesnt have the medium mode. contacted mark about it and he confirmed that if its a gray 7G5CS-U2 then it doesnt have a medium mode. only the black lights have the medium.

i wonder if this light will stay in regulation or end up being a direct drive like taper?

After looking at this, I have a few thoughts.

1) Where’s the surface area? Where’s the mass around the pill? This really limits output.
2) Hardly any work was put into the light, it looks exactly the same as the 7G5CS
3) They’re finally using AR coated glass.
4) Low runtime
5) SUPER flooder. “… with an effective range of 180 meters” - calculated from distance seeing as they’re using ANSI FL-1 standard it has 8.1kcd, which is good for flooding I guess.

Like IE I wonder if it’ll work with the collimator head.

Nice lookin light. 4500k should look sweet. If its under $100 that would be awesome.

Re. 5: You’re right and it’s weird. The 7G10 page at md-lightsource.com, which is also 1860 lumens, is:

So this new light has the same lumens and less than 1/3 the “effective range” than the 7G10, but it’s suppose to be “a thrower” (well the older one was, I think?)?

Wouldn’t expect this to throw like the xml version. The mtg emitter is way bigger than xml. Going from xml to mtg is almost like going from xpg to xml.

That said, that throw distance seems a bit conservative… Which is very un-Chinese of Crelant. :wink: :stuck_out_tongue:

Crelant is definitely fudging the numbers somewhere.

The 7G10: High output at 3 A: 1860 lumens for 130 minutes.

The 7G5MT: High output at 3.2 A: 1860 lumens for 65 minutes.

Question... how does running the same LED harder produce a lower output?

There is also no way this light can be anything but a flooder with some small amount of throw. Maybe with the Aspheric head, or a larger reflector it would be interesting.

Someone at Crelant is having fun:

:smiley:

Assuming that their numbers are correct, the 7G10 has better heatsinking so the emitter would be operating at a higher efficiency.

The peak number taken for max output would probably be before heat becomes an issue in either model of the light.

Heat will definitely be an issue though... 3A in that small piece... it warms up pretty fast (speaking from experience).

I hope they factored in some way to deal with the heat otherwise there will be lots of complaints.

~130 bucks @ HKE!

but only 180m beam distance, pity…

Still no word on whether or not the collimator head will work.

Hopefully Mark from MD-Lightsource can comment once he has them.

That's the only way I would be interested in one.
