The problem is that the amount of tremendous heat produced i think the small fans and the heatsink will not be enough effective by just looking at the images how it looks, the head should have been alot bigger and have 2 bigger fans on each side of the heatsink perhaps to pull out the warm air out faster?, i doubt those small fans will make much difference, and the noise will probably like a small hair dryier, imo very annoying sound lol for very little runtime on highest before stepdown so kinda useless really…
I would rather see light companies push less lumens with active cooling but longer then 60 seconds or something, why nobody wants to do that? the lumens war is getting silly anyways if we cant manage a light that can handle that lumens for less then a minute…
I agree the fan is too small to be effective at turbo mode and will surely be loud.
But I don’t understand why people always say they rather see less lumens that are sustainable when this thing can sustain 22,000 lumens indefinitely according to their specs, which means it is already the record setter for highest sustained output in a flashlight. If you don’t like how the turbo modes are non sustainable, you can always think of it as an extra that you don’t have to use like the blinky modes. But for many people, we enjoy having the ability to blast turbo occasionally when we want to see max illumination momentarily for whatever reason.
Exactly! I’ve used my DX80 two or three times now at 5000 lumens for an hour plus and it made me really appreciate the light. If the MS18 can hit the claimed 22,000 lumens for over an hour and 10,000 lumens for almost 4 hours I’m impressed!
I want to do that. I do have some idea’s in my head but making them real is a completely different story.
True that this is already a big step in the sustainable lumen category. The problem is the size of that thing, it’s a pretty big light and not everyone wants to walk around with such big light.
So the real problem is making a active cooled light that can sustain decent amount of lumens while being small enough for many people.
Of coarse you cant have it all so it’s a trade off.
Do you really enjoy this JCVD moment when you realize that you just blinded yourself for a couple of minutes with 100000 lumens of floody turbo ? :smiling_imp:
Great info here, Jason. Thanks for putting it together. Very interesting to see the active cooling flows.
I wonder if multiple small fans vs. one large fan makes any difference in efficiency. Certainly if one of 2 fans fails, the light can still function at a limited level, versus no fan at all which would be a significant limitation.
They can be equal in efficiency if designed right. Usually the determining factor is the size and shape of the flashlight. Some designs might only have room for small fans. A single bigger fan is usually cheaper and quieter, but it obviously takes up more space.
