The Streamlight TLR-1 HP Handgun Weapon Light delivers 1000 lumens of bright, wide-beam illumination to maximize area lighting and help you identify threats and targets quickly, with a 1.75 hour run time and 65000 candela for extended visibility at distance up to 510 meters. Built from 6000 Series machined aircraft aluminum with a black anodized finish, this IPX7-rated light is designed for dependable field use and extreme durability, having undergone extensive live-fire testing for impact resistance. It mounts directly to handguns equipped with Glock-style rails and all MIL-STD 1913 (Picatinny) rails, and features a one-handed snap-on and tighten interface so you can attach or detach without risking exposure to the muzzle. The ambidextrous momentary/steady On-Off switch, plus a double-tap strobe that can be disabled, offers versatile signaling and identification in dynamic scenarios. Powered by two CR123A lithium batteries, the TLR-1 HP is assembled in the USA and backed by a limited lifetime warranty, representing a trusted Streamlight solution for professional and serious-duty lighting needs.
