SureFire M3LT Review (Pics, Indoor & Outdoor Comparo Beamshots, Runtimes)

Candle Power Flashlight Forum

If the capacity of the batteries is equivalent to the 'area under the output curve' then the runtime for a 'flat regulated' output could be estimated, and shown with the actual output curve for comparison.
 
It's a difficult situation.

Regarding regulation of this light, I believe that the crux of the matter is as follows: This does seem like the limit for how hard CR123's can be pushed for a continuous run. LiIons do have the advantage for this demanding of an application, as has been demonstrated earlier in this thread.

Yes, but the guys in the field don't want to use LiIons during engagements such as fire-fighting and apparently they are the target users for the M3LT :shrug:

As you say sustained regulation with 3 CR123s at the initial brightness isn't possible.

However if there was a light with the head of the M3LT and the body of the M6 (using 6 CR123s) then I would guess that high-lumen regulation would be achievable quite easily.

Perhaps. But more will have to be done to the head of the M3LT to get it to function properly on an M6 body. In its current state, the M3LT head will indeed work on an M6 body. But all you get is low mode only.

Yes, the M3LT is what it is. Clearly it isn't a regulated light when using primary cells.

However, if Surefire thought that there might be a demand for a regulated primary-cell light for dedicated soldiers, then they would have to design a larger body for more than 3 primary cells.

If they ever decided to make a regulated high-output light for civilian use that is still in a compact form factor, then they would have to review their policy of eschewing li-ions and widen the body for 2 18500s which could sustain regulation at the initial level of this light for an hour.

For a longer light (ie 2 18650s), the initial level of light could be sustained for 1.5 hours.

Did anyone ever do a comparative review with the Malkoff Wildcat? The new Wildcat appears to be brighter, have longer runtime, and real (i.e., flat during its initial phase) regulation.
 
Just got myself an M3LT last night from my local dealer. I am impressed by the brightness this light produces in the low mode as well as high. Only gripe about this light is that I really hate the dual output switch. It is too sensitive. On ready position I can't help switching on the light unintentionally, and even though it is only the low mode that I had switched it on to, it is a very bright low output. Can't imagine the tactical guys moving in stealthily, with lights at the ready, only to have it turn on suddenly without intention and thus giving their position away.
 
hi,

which flashlight puts more light otf:

A SST-50 flashlight from Jetbeam (m2s), olight (m31) or maybe thrunite (catapult v2)... or the surefire m3lt???
 
I've used this light every night on duty for the last two months...it's absolutely amazing.

On the first day I got it I was afraid it would be to flood like when I played with it at home before work...was I wrong!

That lens is an ingenious idea... I can be a hundred yards from some bushes in a park that I need to search and it sends a wall of light that illuminates the whole thing.

And today I ge the email that the strobe version is available... I want that one now...ugh!
 
I have been thinking about this light since it came out and dang each day i want it more and more. i only have one question is it a worth it?....i already have an LX2 and a E2DL, which i already love for their TIR lenses. I want a WOW light thats not so huge as other ones i have seen and i think this could be it

i have the LX2 and love it...if you like yours as much as i like mine then you would love the M3LT no less. its kinda like the LX2 on steroids and HGH. its hotspot looks just like that of the LX2 except where the LX2 may have 10-15% of its output diverted to the spill region, the M3LT would be more like 2-3%. i know, that was a pretty arbitrary comparison but thats just how it looks to my eyes.
 
It's not exactly that small a light. I could not seem to find a holster for it yet considering it is so long. Have to carry it in my bagpack on my trips and only taking it out when I need to use it. Once it's out it hangs on my neck via the supplied lanyard.

Other than that I quite like the M3LT. Most of the time I am on 70 lumens setting since it is plenty bright enough for all my needs and only turning it up to the 400 lumens as and when I feel the urge to do it. Do I need the 400 lumens? No. But do I like the 400 lumens? Hell yes! I love it!

The way the TIR works is quite similar to the LX2 except like what stallion2 said about the lack of spill. It does however have a very big hot spot, and the further you shine the bigger the area you cover. That's why I love to play with the 400 lumens once in awhile even though I don't need it. Just so I could see it reach out to 100 meters and light up an entire area.

Thank you for all of your hard work and time put into making this excellent review of the SF M3LT. After seeing the comparison pics between it and the M6, I might just have to save up for one of these bad boys! :naughty:

I'll always hate SureFire for releasing it during the height of Summer. 😛
 
Actually I do love the low output a lot. It is definitely quite bright even though it is rated at only 70 lumen. Felt more like 120 lumen or more than that. As for M6, if it could just be as simple as adding a two stage tailcap that would be great! I really like the two stage output as it is and it will be a pity to see it go.
