As title of this thread states, I have a question about air travel with Surefires or most lights in general. Since they are O-ring sealed and the pressure is greater at lower elevation than the ~8,000 simulated air pressure in most airliner cabins at crusing altitude,..could there ever be damage from barometric stress on these lights? I'm going from sea level to cruising altitude for 14 hours both ways very soon with an E2E and M6.
TSA makes a lot of hype about barometric stress and how it can damage you and/or your stuff if your not careful.(i think the biggest risk for most people is drinking on a plane.)
