The Streamlight TLR-7 SUB USB SLB9 is a 500 lumen rechargeable weapon light designed for subcompact handguns, delivering versatile power with multi-fuel capability that accepts either the SL-B9 USB rechargeable lithium-ion battery pack or a standard CR123A lithium battery to ensure you have reliable illumination when it matters most. With a beam distance of 141 meters and a maximum candela of 5000, this subcompact tactical light provides exceptional visibility for low-light scenarios, while runtime of 1.5 hours on CR123A and 1 hour on the SL-B9 keeps you in the field longer; ambidextrous rear paddle switches offer easy access to high and low settings, complemented by a safe-off feature to prevent unnecessary drain and accidental activation. Crafted from durable anodized machined aluminum and rated IPX7 for waterproof performance, the TLR-7 SUB securely mounts to select subcompact handguns such as the GLOCK 43X, SIG SAUER P365, and Springfield Armory Hellcat, adding versatility to your subcompact pistol accessories without bulk or weight. Weighing 2.39 ounces with a CR123A battery and measuring 2.51 inches in length, this USA-assembled light is backed by a limited lifetime warranty, combining reliability and high-performance tactical capability into a compact, lightweight package.
