The Z2 LED features a virtually indestructible light emitting diode that generates 80 lumens (four times that of a typical two-D-cell flashlight) of tactical-level light, more than enough to temporarily disorient the night-adapted vision of an aggressor. And its super-efficient LED continues producing useful light levels for 11 hours on a single set of batteries. Its high-output LED features a long runtime as well as being shock proof with no filament to burn out or break. The Z2 LED also features an ergonomic grip, tactical tailcap switching, and an anodized aerospace-grade aluminum exterior making it an ideal choice for law enforcement and military applications. The versatile Z2 LED is also a great everyday-carry light.
