A friend says firemen use special smoke cutting lights, but he doesn't have any idea what makes them different. Anyone here know?
http://flashlightnews.org/story76.shtmlUnlike most lights, the UK4AA eLED Fire Light utilizes the company's patent-pending Projection Optical System, which generates a narrow smoke-cutting beam. This ensures there are no whiteouts, flarebacks, or reflective sidelights -- a critical benefit in smoke-filled environments.
I imagine it would be a very, very warm light too.
A very Tightly-Focused Spot.
Helps to reduce the back-scatter -- that is, light reflected BACK to you,
by the smoke particles.
Don't expect Miracles, however.

So a Tiablo A8 would fit the bill...
No, not really.In performance perhaps (just like any decent thrower) but it wouldn't be used due to it's power source, all the lights I see utilized are using "traditional" cells from Alkaline to NIMH (for obvious reasons ) :thumbsup:
The question I was answering related to the use of a Li-Ion cell (Namely the 18650) for SAR applications lithium lights would be excellent however entering fires zones with massive radiant heat (and the potential for flashovers & backdrafts) the last thing you'd want to worry about is whether the Lithium-Ion cell is going to go
I also added the qualifier that the fire fighting personnel I regularly come into contact with are only using a multitude of Alk~NIMH powered lights (primarily Streamlight) YMMV :thumbsup:
No, not really.
The smoke cutting lights (and also dive lights) as I see it, are generally not only built for really tight throw but also for minimal spill: recoil leds and TIR optics are tech you might see here. Also, they're real PITA to use in general duty because of those properties.
actually humans can, (ever been to dry sauna??) sure you don't wanna be there for hours.Lithium batteries can handle sustained temps over 140F (and perform quite well at that temp) humans can't I doubt it'll really be an issue, if the cell gets hot enough to be dangerous the person using it was already dead.
