My two cents.
For a gun mounted light, I'd get a SureFire, in spite of the cost, because they are the proven standard.
If you want a light with some "throw," forget about the LEDs. Even the Luxeons can't compare to a Xenon bulb.
But for very long lasting lights that will fill your needs maybe 60% of the time (how do I know what your needs are??), the LED models truly rock. Personally, I'm a big fan of the Streamlight Twin Tasks, which give you the option of switching between a bright Xenon bulb (which lasts perhaps 2 to 3 hours) and one or more LED settings (which last maybe 25 to 75 hours), depending on the model.
