The Streamlight TLR-1 HL delivers a powerful 1,000-lumen beam, providing maximum illumination for tactical operations, room clearing, and alley searches. Its wide beam pattern effectively lights up large areas, ensuring clear identification of surrounding threats or objects. This lightweight and compact gun-mounted tactical light, powered by a high-lumen lithium battery, offers 1.5 hours of continuous runtime. Designed for rapid attachment and detachment, the rail clamp system easily mounts to handguns with Glock-style rails and all Picatinny rails. The tethered battery door and latch mechanism prevent loss while facilitating quick battery changes. The TLR-1 HL features an ambidextrous momentary/steady on/off switch, and a strobe function activated by two or more momentary paddle hits. Included are keys for Glock-style, Picatinny, Beretta 92, S&W 99, S&W TSW, and Sig P320 rails, along with a dual remote pressure switch, mounting clips, adhesive pad, and cable ties, providing a comprehensive solution for your tactical lighting needs.
