The E12 is exactly what you'd expect from a true tactical flashlight, with comfortable knurling for a secure grip and forward-facing tail-switch for activation and mode selection. The E12 has three separate output modes high- 130 Lumens, medium 50 Lumens and low 8 Lumens. Rubber O-ring seals help keep this flashlight waterproof to IPX-8 standards, meaning it can be fully submerged in up to 2 meters of water for up to 30 minutes. Includes 1.5 AA Alkaline battery, spare O-ring, E12 user manual, warranty card and lanyard.
