Designed for sub-compact pistols, the TLR-8 SUB combines a tactical weapons light and laser for enhanced pistol capability. The low-profile design and paddle switch prevents snagging and accidental activation is prevented with the "safe off' feature on the bezel. At only 2.51" in length the TLR-8 SUB emits a blinding 500 lumens (5000 candela) of white light and has a 640-660nm red laser for pinpoint aiming.Specifications and Features: Item number 69411 Fits: Glock 43x/48 with Rail White LED and Red Laser 500 Lumens 5000 Candela Beam Distance 141m Run Time: 1.5 Hours (Light Only or Laser/Light Combo Run Time: 60 Hours (Laser Only) Attaches to Rail Without Putting Your Hands in Front of the Muzzle Ambidextrous Rear Paddle Switches User Enabled Strobe Function Safe Off Feature on Bezel IPx7 Waterproof One CR-123A Lithium Battery Length 2.51" Weight 2.77 oz with Battery Anodized Aluminum Black Includes:(1) CR-123A Lithium Battery Mounting Kt with Key
