The Streamlight TLR-1 HL is a high-output rail-mounted light intended for pistol and long-gun use. The unit uses a high-output LED and precision optic to produce a concentrated central beam with usable peripheral spill for target identification and area awareness. The housing is machined aluminum with a hard-anodized finish and a clamp-style Rail-Lock mounting interface designed for secure, repeatable attachment to Picatinny and many manufacturer handgun rails.

Controls consist of ambidextrous rear push buttons that permit momentary or constant-on operation; a user-programmable strobe function is available. The light is powered by two CR123A lithium cells that are accessible via the bezel assembly and are supplied with the unit. Construction is sealed to IPX7 standards for temporary submersion and uses a shock-resistant lens. The TLR-1 HL is designed to retain position under recoil and to be compatible with most light-equipped holsters.
