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.
It would be highly unlikely for the threads to strip since they’re an order of magnitude harder than the aluminum they’re threaded to. It just appears snapped because the screws are counterbored into the head.
being stripped from the head is what I said, so that includes the female threads in the head, but likely or not you also can’t assume they were damaged either like Jason said earlier…maybe the guy took it apart to modify it and wanted to complain about it because he just didn’t like how it was made, no that never happens here, he gave no context. He only served to stir up trouble, like help is needed there. This is exactly why most manufacturers just put out their products and don’t really care about this forum, everyone here wants to control their design, description, marketing strategy, prices, and policies. It’s become much worse that feedback and suggestions. Give an inch, take a mile.
To me this looks like it was in the process of being disassembled but it’s hard to tell. Would be nice to see the other side of the light for drop damage. Either way, I would call it misuse. I know they are heavy but in my opinion it would have to take a SERIOUS drop for that to happen. In the meantime I would not assume anything negative until we get more info.
Only responding to your quote bout needing to replace the SHCS…
It’s very easy though to accuse the end consumers… Give the manufacturers an inch they take a mile. Except here in the US if you were a business giving customers 71% of what you promise you’d be done in a year. Here if a manufacturer does that everyone praises them for being innovative and at the cutting edge!
I really don’t know yet if the throw distance on the R90TS is any better than my R90C, though lumens are definitely “doubled” based on realistic figures, so that’s good, but at the same time the R90C has close spill. I really like it because I can see my entire yard and the ridge behind me, but some may not like all that spill. It will be interesting to hear some opinions on the the throw, the spill, and the efficacy of the objects at distance, and photo comparison to an R90C. I know Martin has both
Like I said a month ago about these high power lights, they don’t have CPU style cooling to keep temps down, sustained output will be rubbish. In other words these lights will just be toys.
