Imalent MS18 with 100,000Lumen and R90TS with 36,000Lumen

You don’t need hundreds of CFM because the body has surface area too. Manufacturers could easily make an extrusion with internal fins, exponentially increasing surface area. They could also add through holes to allow heat pipes from the head. There’s no rules stating that one must hold a flashlight from its body; a separate, ergonomic handle would be great - you can make it adjustable, and you can hook the handle onto your belt or backpack strap. And with the ginormous head this thing has, an external handle could have a more forward design, which would make the light balance better on the hand, instead of being head-heavy. You can have the handle mount to a t-slot in the extrusion, which would make it adjustable, and able to mount the light to whatever you want. And thus, you don’t have to think of the body as having to be round.

CPU heatsink you say?


.

I built a spotlight not long ago using a Fresnel lens, and an Osram White Flat 2mm^2 LED, mounted to a 90mm dia. x 50mm thick aluminum heatsink, actively cooled with a 12V fan pulling fresh air through the fins, and exhausting out the back. I’ve pumped a max 34W into that LED and you can feel the warm air coming through the exhaust end, even in the cold winter here. I can’t imagine a smaller heatsink and fan dissipating 20-30 times that power - just to squeeze out another 5 seconds of turbo time?

I’ll stick with the GT4 over the Imalent R90ts. With 18 LEDs I don’t see how those tiny reflectors will be deep enough to throw 2000 meters. And with the qc issues Imalent has had, not to mention the grossly exaggerated output numbers, I just don’t feel like I would get what I’m paying for. I don’t care if it’s a million lumens. Doesn’t matter if it doesn’t work.

Did I mention 10% of my company sale went for new machinery and RandD? I could of just pocketed that and let the company rot away. Maybe even a few bank con jobs along the way.

As an engineer, I paid nothing for the actual engineering, but prototypes, trips to see machinery capabilities, making/modifying machinery, sending samples to customers, material testing……it’s expensive and chances are, the market won’t buy it.

It’s not surprising that most of the products out there are copies, or copies with a bit of a change. The vast majority are styling exercises. True usability/efficiency breakthroughs are not as common as they appear considering the size of the market.

Then there are the copy cats, mostly foreign and out ovf the reach of lawyers, that will suck away all the innovators hard work. And the retailers who don’t give a damn if some cut rate foreign company copied your product, as long as it was cheaper to them and more profitable.

Yeah, I have a chip on my shoulder about this…anywho, back to 1 million lumen flashlights.

Do you know that CPUs are in the 150 watt range? Some way higher. Yet they can run continuously with their fans on.

CPU fins and fans are available in surplus stores.

Any discussion on output sustainability and very high power lights has to start with fins and fans.

Ummm….you need the cfm to push the air through the fins. Passive or low air volume is not enough in close spaced fins. That is why CPUs have fans. Noisy fans.

But otherwise, keep going……you’re heading in the right direction. Forget the body, work the head. Lol

i was actually wondering: how mature will these lights be?

I know Acebeam takes many months before a light gets into production, but Imalent

seems to add them almost by the week....

That worries me a bit.

Im more curious all the legal stuff, can they get away with this, imean just looking the numbers if we asume its real, is there no limit for lights and how much lumens they are allowed to have? I also think on highest whatever the lumens it will pull u will probably get blinded on the ground just pointing the light , saw the same thing with acbeams x70 so much light goes into the ground and bounces back into your own eyes…. cant see how the max output will be high just a very brief moment :…

weird it has less intake holes then ms12 if that design will be final, looks weird that head is supposed to handle 1300w of power…

No limit at all, why would there be? Maybe the Swedish government is a bit too “hands on”?

no i mean shipping them worldwide, really no regulations shipping furnace lights at all with serious flaws ?

Well, the batteries are fully contained in a metal housing. I think that’s the big thing with shipping batteries out of China. Some stores in China, BG, GB, AE, seem to be able to ship batteries in plastic cases. I’m not sure on the legality of that.

As far as flashlights, Customs doesn’t know if a certain brand flashlight is reliable or not. I’ve heard of zero cases of batteries combusting in Imalent lights.

The 2000 lumen GT uses 8 cells, the 100,000 lumen MS18 uses 8 cells. No big difference to Customs, really.

all that hatred and bashing does make some people here look like trolls...

please stay fair and constructive!

help us paint the picture about problems in the past from your own experience.

if 10 people say "I know their leds burnt in the DX80" and those 10 speak about the one guy who posted his personal experience we tend to think it's 11 dead lights ;)

I am sure if I took a Koenigsegg for the daily duties I ask from my Fiat Tipo it would break sooner than it should. (NO - I have no Koenigsegg ;) )

but for driving sportive if there is a hour available and sometimes on the track the koenigseck will definitely be the much more pleasant choice!

also I love to hear from people who had problems with their R90C, R70c, RT35 and RT70 - imho Imalent tries hard to improve.

or is there another reason why crowds with pitchforks and torches ( :D ) are rolling thru the forums every time when a few brands are on topic?

first video

seems the cooling has improved

I have the Imalent DX80 for about a year. The second version. I bought from the EU warehouse for $ 216. For now it works perfectly. Just like HR20, DN70 and DM21T.

No complaints about the MS12 battery pack, from what i can tell its genuine Sanyo 20700, admittedly I am only going off the wrap colour lol.

It looks like they’re using a single 30mm to 40mm radial fan. They also made it easily accessible by 2 external screws. This should make it easier to clean dust as well as to replace a fan that gets damaged or stops working.

Notice that Imalent is using non-anodized shoulder strap attachment points on the body and tail. Most manufacturers don’t so you scratch up the body; I’m glad someone is finally doing it right.

The heat sink I describe is finned… It is not a new idea to use a CPU heatsink for a LED; many folks do it here, even I used one for a COB light project.

But think how large a heatsink for just a 100W CPU is.

I was under the impression this was an open forum for the good and the bad. Everything I have seen mentioned on the negative spectrum has been true. If it is “trolling” to give an honest opinion about a product, it certainly must be the ultimate “troll” to market a light as xxx amount of lumens when really it doesn’t reach that mark or come close. If a company doesn’t want to be called out for advertising false numbers, they shouldn’t advertise their products with an increase in output that doesn’t exist.Same goes for fairness. It’s not fair to the consumer who purchases anything and only gets 75% of what is promised. Would you buy that fiat if it only came with 3 wheels and delivered 75% of the horsepower?

However, that does not mean they don’t make bright powerful lights. They absolutely do, their lights are impressive and I don’t think anyone is saying otherwise.
