Re: Surefire Fury
Your'e right, polycarbonate is less likely to break than glass so it is superior in that regard. And SureFire glass is 4-5mm thick, my guess is for strength (I'm talking about the pyrex lenses, not TIR optics). But the polycarbonate lens used in the 6PX and G2X scratches very easily. I scratched one of mine badly when I wasn't thinking and cleaned it with a paper towel. Won't do that again...
The main reason SureFire ever went from Lexan to tempered glass is because the window was susceptible to 'melting' damage from the high temperatures generated from the high-output incandescents. Given this isn't an issue with LEDs the reasons not to use polycarbonate are less clear cut.
