“magically” is a big derogatory. There are coolant liquids designed to help dissipate heat. I have seen computer motherboards that use a cooling system in conjunction with assisted air circulation.
Well, take a look at the Imalent MS12… it has an internal radiator & active cooling fan. Granted, this form factor flashlight is not small by any means, but it’s still hand-held. FWIW, Acebeam X70 in video below has an add-on cooling fan mounted on it.
Of course worth mentioning Imalent’s MS12 successor, the MS18 that also features an active cooling system with fans and allegedly a coolant liquid:
Liquid cooling systems in computers work because they pull the heat away to a much larger radiator in a different part of the computer thats usually right at the vents, vs a heatsink and fan circulating that heat through the case.
The fans in the Imalent lights work the same way, actively blowing heat off of a heatsink and out of the light. I really don’t know if a liquid cooling system in something that already relies mostly on conduction and has vents right there at the sink would help. Pulling the heat away from the head to a heatsink and fan setup elsewhere on the light would require a lot of space.
Heat pipes also incorporate liquid cooling in an unusual way that takes advantage of a phase change. Taking advantage of a phase change is possible, but difficult. Going from solid to liquid would probably be the least difficult. I wouldn’t be surprised if the benefit was so small that it couldn’t be measured reliably outside of laboratory conditions.
A review of this light was posted by Unix5566 about 24 hours ago in the German forum. I have not yet received the two that I ordered, but that is ok, I ordered as soon as I could when this light was announced. The 21700 battery is removable, and the battery has a USB-C port for charging, which makes the battery longer, so normal unprotected 21700 cells are not long enough to make contact inside the flashlight. Also, the Imalent USB-C rechargeable battery has some type of a special configuration at the top end, so I will be looking to ordering extra Imalent batteries for this light.
Mode spacing looks good, and double click from On or Off for Turbo is something that I like. The reviewer states that the flashlight is very compact for its max output, which is the main idea for me. Normal modes are available for normal runtime and normal heat generation. Briefly, for a second or two or few, to brightly illuminate a large area, is what I will use this light for. I can then throttle back to normal mode after a few second scan of the large area.
Thanks to Unix5566 for his review!
By the way, for more than a few weeks, I have noticed that user Imalent has been conspicuous on this forum by his absence. For about two months, he has been very active on another location, but not here. Then, today, I noticed that he is Banned at that other location. :huh?:
I’ve taken a few looks at the battery from different sources. It’s single contacts on each end. The top of the battery appears to have a plastic reverse polarity shield. In this video you can see the tail cap has a long tail spring IMALENT MS03 Open box review - YouTube Hopefully this will allow other standard length batteries to fit.

That’s good news, thanks for noting that and reporting that. That means that normal unprotected batteries with solder blob or a spring soldered onto the anode will probably work.
I believe no battery modification will be needed. With the positive ends shield being so deep. The lights anode contact is going to have to extend out some.
A 40T does not work due to its length (or lack off actually)
A normal cell will work but it needs a magnet or so, since you will need a giant blob of solder, since the unprotected cell rattles in the tube.
Nice light, does not look like 13k lumens, floods more than a KR4, gets hot quick.
The screen printing is sloppy, the threads are very thin.
Thank you for your valuable pics and observations. I’m going to ask my favorite modder to provide me with a few soldered spring top unprotected 40T cells. I hope to get mine soon. Thanks again!
