Imalent MS12

I put two videos on YouTube to show turbo mode, and the fan.

 

Running through the modes.

Turbo Mode

Checking out the fan.

https://youtu.be/CIMQA6o_DZg

 

I have done some quick and dirty math, to test out the cooling capability of the internal fan.

 

Methodology

I turned the flashlight on turbo mode and monitored the rise in temperature with my IR thermometer. My IR thermometer has proven to be very accurate and it has decent precision, with the uncertainty of my measurements being 0.1ºC.

Using Newton's Law of Cooling

Where T2 = T0 + (T1 - T0) * e(-k * Δt)

k~=0.00121372 with the fan.

k~=0.00024896 without the fan.

With Fan 45.5-35ºC ~ 10 minutes ΔTemp = 10.5ºC

Without Fan 46.1-43.2ºC ~ 10 minutes ΔTemp = 2.9ºC

Clearly the fan does work. I have not tested to see how it extends runtime, I will do further testing with my new lux meter on Thursday or Friday.

 

Check back later this week for more data.

Thanks for the videos. So what you think of the light so far? The light doesn’t seem like 53 k lumens. Fan sounds pretty loud.

Personally I believe the light output is pretty impressive. I would say somewhere around 35k-40k lumens, but I will know a bit more tomorrow when I get a new lux meter in. Build quality is pretty good other than the switch, which is mushy and it sticks so I will probably try to take that apart. Fan is a bit loud but in these videos the fan is only inches away from the mic. The side lights are very nice and have different brightness levels. The side lights would be good for reading in a tent. No direct UI setting to start in low mode which is disappointing. The camera doesn’t really capture how much spill it has mainly because I am using a 35MM focal length lens.

Here is another video running through various mode. Camera ISO was a bit higher in this one so a bit overexposed.

Is it like the DX80 where everything looks kinda washed out when on turbo because it lit up closer surroundings to the max?

I don’t have a DX80 but they are both spill heavy lights so I believe to pattern is similar maybe more throw on the MS12 because of the larger reflector.

Will watch them..glad you got yours man.still waiting on BG to ship mine..but i think its harder to tell the difference in output as we go up in lumins…but still will be Amazingly bright.

how hot does the head get after it steps down with the fan ? 45c is that right ?

Did u try submerge it see what happens, it says 2m waterproof ?

Risky.  The dx80 had a water rating too and the last I heard, when someone dropped it in a foot of water it died.  They said they could even see the driver through the side fins.  Imalent has some sketchy specs in that regard and I don't know how they get away with it.

That fan is so weak. Seems like Imalent just slapped it on to beat Acebeam to the market. Thanks for the great videos.

Yes i know, but i mean lets sain theory u would drop it in a lake when u are out camping or whatever, surely the light would have to survive it no ? Or just walking with it outside when its raining heavy, I agree that its bad if a light with a ipx rating dies if it comes in contact with water, somethings not right.

Also i wonder how a are u supposed to clean the fan over time? because dust and crap will stick to it like on computer fans if u dont clean in a few months its all clogged upp from dust etc.. must be a hazzle if it stops working to send in the whole light to Imalent ?

I think that if we have the DX80,it is better to get a R90C than a MS12 .

If I got the light for free to do a review, I would test it in water but I doubt anyone here would like to do that with their own light  considering what it costs!  Good point about the fan.  I wonder if Imalent made it accessible for occasional cleaning?

No way to access the fan, maybe if you disassemble the head which I have not tried. I am definitely not going to try exposing it to any water unless it is distilled water. Silly

I did measure output in my 3.5” lumen tube from TA, I used maukka’s calibration lights to test the new lux meter. This is an incredibly inaccurate way to measure luminous intensity because the head of the flashlight is 5” in diameter, there is an incredible amount of light escaping. My GT70 measured almost 3000 lumens apart from people with a integrating sphere. That being said, it measured at 25,000 lumens. I am working on sourcing some 6 inch PVC to build a larger version of the same design.

The fan seems to kick on at 50 degrees Celsius.

25 000 on turbo? not more ? u dont happen to own olight x9r? would be fun see how much more bright it is compared side by side….

The fan seems to rotate very fast by hearing high pitch noise of it.
They are really nice light, i might get R90C later.
Too bad when charging user has to unscrew battery tube. Not convenient when doing topup from time to time.

cool i'll see you when you get there

So i assume you got it? If so CONGRATS… Mine should come this week..so the charging if on the battery itself??

I haven’t purchased yet. Still waiting for more details to know how good it is.

I hate switch that sticks. I have one HP desktop that has power switch that sticks, so when i power on the desktop, it sticks and i have to quickly try all efforts to unstick it, 80% chance the desktop would shut down.

cool i'll see you when you get there

Thanks a lot. Please do candela measurement, preferably outdoor if you can. Indoor will have too much reflection contribute to lux measurement.

Why would you expect more? The flashlight head is 5.1” in diameter and the Lumen Tube is 3.5” in diameter. So a huge amount of the light is not even going inside the Lumen Tube. If a GT70 only shows 3000, then 25000 seems about right.

When you get up to big lights with really high outputs you need to switch to a bigger integrating sphere. Like a big styrofoam cooler.

You start to run the risk of melting the diffusers in the TA Lumen Tube.

No problem..sorry i dont have any measerment stuff..DONT WANT ANY NEITHER..WILL MAKE ME CRAZY.but i got a DX80 TO COMPARE.

No problem. DX80 is flooder while R90C is thrower. But we still can roughly know how well R90C perform by comparing side by side.

I think that the best measurement is this comparison with the DX80.

+1000.
I also believe that if we have a DX80,we don’t need a MS12,but we can think bying a R90C.

Im confused, light is claimed over 50k lumens, that to me is a bit low? i know even if u take into account loss of light etc its still a bit low too me and false marketing imo…. the actual lumens on turbo would be interesting to get.

Or do u mean in a perfect calibrated tube that can handle that much lumens it would show near those 50k ? then i understand.

In my head, comparing my GT on the 3.5” lumen tube, I would expect it’s real output to be 40k-45k lumen if you could get all of the light into the tube. It’s just a wild guess, but it makes sense to me.
