Here’s the deal: They could have used 24 XHP 70.2s, ran them at a more reasonable 12V and 2.4A, and produced 100k lumens rather “easily,” while using about 30-40% less power (less heat); AND have enough overhead for turbo.
Heat pipes only tend to work well at very high temperatures and are usually a last resort when you can’t get a cooling fan close enough to the heat source. I think it would be very strange if they were actually using heat pipes. Then again, I have no idea what’s going on inside of the MS18 other than it seems to have a single radial fan about 30 or 40 millimeters in diameter. Who knows, maybe it has multiple fans inside.
really ? never seen a light that big so broken before, it looks like it just snapped, either way it shouldnt be a 2 part head since it weighs some it should be supported better then somehow. a few dents and crack if u drop it is no big deal but looking that picture it looks bad imo…
Thanks for the translation 59. The R90C has nothing to do with this thread, but to answer his question, the head of the R90C has a small allen screw above each lantern, probably for servicing and ease of assembly; you can see in his photo that each screw is hanging down onto the two lanterns (which read R90C). You can’t tell if they were stripped or broken from the presumed long drop, but if the torch still works, they should replace those allen screws.
Imalent seems to be using the same basic head design for both the MS12 and R90C (with the MS12 having more air slots). The MS12 has to be a two piece design in order to get the fan inside.
We should not assume what the situation is concerning that picture. One person might have taken their R90C apart and posted a picture and another person might have seen the picture and freaked out thinking it’s broke. Who knows.
