BB2K Airsoft got his on another tactical light, the compact Wowtac BSS V3. This has 1150 lumens brightness with the Cree XP-L V6 LED. It is powered by a 3400mah 18650 Battery and is encased in an aircraft-grade aluminium body... "The Wowtac BSS V3 is a compact tactical flashlight. The included red filter, the Battlecrone and the extra button for the strobe make it almost the ideal companion."

Mount it to a rifle or a pistol, the Valken LED Flashlight/Laser Sight Combo is a good solution for use in low light conditions. You can get one at Airsoft Atlanta... "The Valken LED Flashlight / Laser Sight Combo Pistol Mount is a high quality solid combo unit that attaches to your pistol's front under-rail. Should work on most pistols with a standard rail system (all airsoft). Red laser beam, 200 lumen flashlight power.
