Imalent MS12

Right, all flashlights use convection (unless they are in a vacuum), but it’s relatively weak. Using a fan is called forced convection. It greatly speeds up or helps the heat transfer.

Even though other MS12 users show air entering one side and exiting the other, it’s not a straight forward flow. The fan style they are using just seems odd. I’ve never seen that style of fan used like this before. The only thing close was the FB1 below.

In fact, here are all the airflow patterns on the active cooled lights I know of.

The prototype Olight X9.

I’m guessing on this Microfire due to lack of data.

The protoype X70. It had 3 fans so it looked like it had 3 dividers using 120° of the diameter. So it had 3 inlets and 3 outlets.

The new version of the X70 has the external fan and “looks” like it has air blowing across the exterior.

I am still guessing on the MS12 design. Their fan style and layout is very odd. I’m guessing they are using a divider to get the air to go in one side and out the other, but it’s not working very well.

Used in laptops a lot.
It’s a centrifugal fan. Picks up air in the centre and blows it out the outer perimeter.
It basically spins the air that’s in there and flings it outward.
Very effective.
Vacuum cleaners work that way too.

You misunderstood me. I’m familiar with all fan types, but centrifugal is not often seen inside flashlights. The FB1 uses a centrifugal, but it’s orientated differently.

Yes the type of fan in the middle of the light makes no sense to me, it doesnt seem like its magical just sucks the cold air from one side and throws out all the hot air on the other side, if it was that easy other light makers would have figured that out long before imalent, it doesnt take a rocket scientist to figure that out.

Would be interesting see the inside of the head if there are air channels or something to get the flow out somehow…

They have to call a aerodynamics expert to fix the problem. :slight_smile:

Imalent should be held responsible if this flashlight burn someone accidentally. To be king of lumen it must also take care of user safety. I can’t imagine those who has less flashlight knowledge paying full price and get themselves a dangerous tool. If buyers think MS12 gets too hot in such a short time and request return for refund, would Imalent accept return? Sport car that can accelerate very fast will also brake to still very fast, it’s safety that is utmost important.

I think Blippi at ASF got 71c for his heat test at the head, kinda in the middle of the 3 tests I did. I’d be interesting to see if that was from a full charge.

Bridgtec commented his fan was quiet which seems odd.

did he ever say something negative in his reviews?

I think the Fan design is not perfect

but before I post my conclusion I need to open the light to see if it's fixable or not.

the MS12 and R90C are 100% not toys and should handled with care!

What do you mean exactly?I ask because I’ll get a R90C.
I pass MS12 because I have the DX80 which is more than enough for me.

Are you calling Matt/Vestureofblood Blippi? Where does this name come from?

Not toys ?? :partying_face:
Well, not children’s toys, that’s true.

He mentioned the MS12 needs a layer of polystyrene over it in the box to stop the lid denting.

toys for big boys then.

I’m not convinced, that Imalent MS12 can be really worth more than 400$. I saw video with turbo mode and saw the other videos with Professional Police Flashlight and I can write - this one can be much better than Imalent DX80, but not for this price.

Worth or value is all relative. If it’s not worth $400 to you that is fine. It is worth it to some people, but not others. This is just the way things are.

Yes, I know that is not flashlight for daily use and you can always put there some Swarovski crystal and sell it for 1000$. I just only wonder, who buy flashlight like this one.

Several people on BLF have bought them. I kind of see the appeal. It’s super bright and awesome.

It’s the little 18650 lights that people buy for $300 that make me scratch my head. :disappointed:

Can you post some links to videos of Professional Police Flashlights? I was always under the impression that they are about 2000 lumens or less.

Martin and I are under the impression Dave 7 is a spam bot.

I found the video like this https://www.youtube.com/watch?v=tfHuNH316co
