[Review] Convoy M3 (Cree XPH70.2 , 1 x 26650) #Update 01.02.2020: Modded with Thermal Pads - New Turbo Graph added!

Convoy M3 has 4 selection of tints that will suit well for customer need which is really greats!

Convoy M3 CREE XHP70.2 :

  • 6500k(cool white)
  • 5000k (cold white)
  • 4000k (natural white)
  • 3000k (warm white)

Wow, this seems like a very well rounded flashlight!
I’d adjust mode spacing a bit and maybe add some more modes but this is still decent.

At 184μΑ a 4000mAh battery fully charged would drain itself in 2.48 years. Or 3.37% per month

A few Qs, do the different temp emitters have the same lumen outputs, is the lens AR coated and anyone know if my old King Kong 4000mAh 26650s will be able to fuel this beast? :smiley:

I have mine in. I like it very much. It does seem to do a bit better with the Golisi 4300mah over the litokal 5000mah

Thanks for the review. Looks like temperature regulation needs improvement, but overall very nice light.

BTW, where did you get that 21700 to 26650 O-ring?

O-rings come with the light. I’m using the Shockli IMR26650 5500mAh battery however and it’s bright. Very happy with the light even in mode spacing. My only gripe is that turbo cuts out at too low a temperature. With its mass the light is just starting to feel warm when turbo cuts off. It took several turbo resets to get it warm. Some resets only a second long.

Regarding the output vs light’s temperature, in theory colder temperatures produce more lumen.
With that being said, I would suggest to leave the output hunting game aside and pick the a tint that you like, cause nothing can beat a tint that’s pleasant to your eyes :slight_smile:

As said, the ultra thick o-rings arrived with the flashlight!

In lumen monsters i want raw brightness.
In other lights i go for neutral colours for aesthetics.

In the past I was all about raw output in each and every light.
Times change, and now I appreciate a nice tint and CRI :smiley:

Even in a floody light if the output is high enough you’ll have way more blowback/backscatter from a cooler temp. I see beamshot vids all the time where you can’t see what they’re aiming the light at, at all. :weary:

You can never have too many lumens, if you wash out one situation then you an find another where you don’t have enough. That said lights have modes for this reason.

Is that a timed step down?

It’s a thermal sensor set so low that it trips in about 30-45 seconds. Light barely feels warm when it steps down. Repeated turbo clicks after that last 1-3 seconds.

That’s a shame. Looks like a good light otherwise.

I don’t mean the output is too high, but rather that the cooler the temp the more light scatters in the air and the more the beam is visible… which wrecks eye adaptation and obscures whatever you’re pointing the beam at.

I wonder if anyone has tried to put some thermal pads on top of the driver to dissipate the excess heat.
That way the Turbo runtime should be increased.
I might try to purchase some pads online and see if things improve (they should).

Well then the obvious solution is even more lumens :wink:

I just ran it partially with the electronics outside the host. The driver slightly heated up then kicked in the drop. I believe she is just programmed too low on temp kick in. I don’t have any on hand but a big dab of thermal doping will probably help. In or out, kick in is about the same time

He arrived yesterday. After switching off one chip slowly goes off. What can be the problem? Poorly soldered LED?

Niiiice. That’s the first time I see a comparison with the L6, a torch I always wanted but couldn’t get. Also more compact form factor but most importantly single-cell, with all the quality-of-life advantages of it such as no need to pair batteries from the same batch or needing a 2-bay charger to charge it in one go.

That’s not right. 5000k is neutral white, not “cold”.
