Hmmmmmm,
My favorite light (meaning you could only have one), need to list my requirements
Must be bright
Flood and focused beam
Use alkalines or rechargables (can't have lithiums on military aircraft)
Must be LED as bulbs blow out
Interchangable color filters for blackout conditions
Locking tailswitch
Regulated for max brightness
Small to hide it in a shoe
Run on AA batteries (available world-wide)
Look inexpensive so it won't be stolen
Cost under $100
Cheap to replace host if damaged
Last a few hours on batteries
Be made of aluminum to cool regulators/LED
Have rubber grips on barrel for "grippability"
The great thing as I have one of those lights /ubbthreads/images/graemlins/grin.gif
The Brinkmann Legend 2AA with Badboy 400 Q3L (coming soon to replace BB500) with NX05 optics, McFlood optics for flood and head removal for candle mode. Runs on 2 AA alkalines, has color filters for blackout, multiple optics, runs cool, regulated LED so it won't blow a bulb or attract insects, has rubber inserts in the barrel, locking tailswitch and people think it is a "normal" flashlight so it will not walk off.
Heck, even the Kurds love it! /ubbthreads/images/graemlins/thumbsup.gif
