what is tailcap lock-out?

Hey,

Quick question for you folks. I'm about ready to purchase a Surefire 6P LED light and read that it has "tailcap lock-out" capability.

Can somebody describe what this is exactly?

With a twist-momentary tailcap, you can use it several ways. Fully tightened down, it's constant on. If you back it off a bit, you can press the rubber switch for momentary. If you unscrew it a little further, the light will not come on anymore. Useful for storage and transport. It's how all twist-momentary lights operate.

Not all of them, actually. My SL TL-3 doesn't lock out, even with the tailcap unscrewed almost to the point of falling off. It'd be nice to have a lockout, for sure.
