The V2 Vampire Dual-Spectrum LED Flashlight (Black) from SureFire is a dual-output flashlight with both white light and infrared output--no need for an IR filter. It has a virtually indestructible power-regulated white/infrared LED assembly and a precision Total Internal Reflection (TIR) lens. In white light mode, the tactically correct two-stage pushbutton tailcap switch lets you instantly select an output level: press for a 10-lumen long-runtime low beam ideal for general night use; press further for a 150-lumen white spot beam—more than enough light to temporarily blind and/or disorient an aggressor by impairing his night-adapted vision; twist for constant-on low beam, twist further for constant-on high beam.
A push-twist on the V2's self-locking selector ring lets you switch to infrared mode, where the tailcap switch again lets you instantly select output levels—press for a 10-milliwatt low beam, press further for a 120 lumen high beam, twist for constant-on at either level. The V2 Vampire is 5.7" long with a head bezel diameter of 1.37". The housing is O-ring sealed against moisture and dust. Two 123A batteries are included.
