The ultra compact T1A Titan flashlight boasts impressive output from a single 123A lithium battery, but it also offers a near infinite range of lower output settings which allow you to conserve battery power or preserve your night vision when doing close work like map reading. A virtually indestructible power-regulated LED emitter and precision micro-textured reflector produce a smooth beam that's selectable, with just a twist of the bezel, from zero to 70 lumensùmore than three times the output of a much larger two-D-cell flashlight. The stylish T1A Titan is small enough to attach to your keychain, wear around your neck on its included lanyard, or stay in your pocket for easy access.
