Astrolux MF03 - new pictures + video

Did you really think a bargain light company like Mateminco would come out with such an advanced design?

To have active cooling in a flashlight, the company would have to open an entire new division of the company just to focus on that.

Small companies that make bargain lights just can’t afford to do that. Maybe bigger companies like Olight can do it eventually and without too much expense. All that new research and development costs money, though.

So when we do finally see an active cooled flashlight make it to production (and not just slapped on haphazardly light the Ra light) I’m sure it will be expensive. Like when the very first curved TV came out or the first 4k tv came out. This new technology carries a price premium. Over time though other companies can study and copy their competitors and come out with their own active cooling system. Eventually you will see the prices come down and more lights will use it.

Active cooling is like bleeding edge technology. Olight tried and failed at it with their X9 Marauder. I think they are going to try again with a new light coming out soon. I forget the name of it.

We all agree this is the best looking, right?

That looks great to me. Just clear anodize it so you still see the machine marks. It would have that awesome raw aluminum look.

:+1: :+1: :+1:

Check out these pics of the prototype Convoy L2 finish. It’s a clear anodizing with no sandblasting. It looks great.

i will ask if thats possible ;)

I think it took Simon almost a year to figure out how to get the finish in the pics I posted. His normal “clear” lights like the C8, L6 and S2+ are sandblasted and don’t look as nice.

Maybe you could ask Mateminco if they can do less cutting on the light around the head in particular. The big slices on the head make it look pretty ugly.

Even if clear ano looks cool, but black improves the cooling a lot so the light has more sustained lumens

My guess is the light will use multi-emitters with TIR optics or small reflectors.

If it were a thrower with a giant reflector it would not be possible to have those super deep fins connected to a thinner stalk.

I don’t believe that. Maybe you get 1 or 2 degrees cooler, but not something you would actually notice in the real world.

Black or white are equally emissive. But polished shiny surface has really low emissivity. I think we should avoid clear ano of aluminum for high power flashlight as it can’t radiate heat to environment fast enough.

Nothing is polished. Just fresh off the machine then clear coated.

Black looks good, too. To each his own.

I wish we could get some more info on this light.

I put this info elsewhere as well. Maybe it is of interest? How hot does an S2+ get at 2.75A? Comparing an anodised Convoy S2+ with a fluorescent yellow powdercoated Convoy S2+

I think all color will be very close in emissivity. Just that the clear ano coat that maintain aluminum silver shiny surface will have very low emissivity.

It will be great if a proper test done on them to confirm or end the disagreement.

No, I don’t think it relates to lights this size. Personally I don’t let any of my lights ever get hot enough to step down. I almost always use them in short bursts. The only thing a black color might do for me is give it a few more seconds of run time on turbo which I don’t need. I’d rather have a bit more thermal mass to slow the heating up process.

For other people, maybe they want slightly longer run times at lower levels? I guess if the brightness level is just right, the black finish might allow it to maintain steady output while the silver might not. That’s a rare situation, though.

It’s not that big a deal to me. I don’t think they can do a silver finish anyway. It would just be a nice looking option that would attract me to it.

INDEED! :open_mouth: I’m losing sleep over this, gawd, to get more of run time in Turbo and all other levels will be Earth shattering, change life as we all know it! :person_facepalming:

What is the superior heat shedding coating!!! :money_mouth_face:

Ohhh the angst of it…. :person_facepalming:

Anodization is what dramatically increases the heat emissivity of aluminium (because it increases the surface area). Bare aluminium is really bad on the other hand. The color is not important.

There is no secret coating. Only increasing the surface area even more by using large heat fins with the correct spacing will have an additional large benefit. Check out aftermarket PC-component heatsinks to see how cheap, effective heatsinks are made.

This is sarcasm, right?
It can translate poorly over the internet. Plus there are many non English speakers here. I always make sure people know I’m exaggerating because people WILL take you serious. :wink:

Well, i like to use Turbo mode for 10+ minutes with randomly switching to low/off for like 10s to reset. After that, it is getting very hot, i would grab another flashlight to play like this again. If a flashlight can only do 1-2 minutes turbo, i don’t think it is good to use it this way.

Ya, i don’t know why Kawi got so excited over this. Looks like his sarcasm is exciting type.
