Streamlight makes high-performance lighting for professionals, from handheld and weapon-mounted lights to headlamps, lanterns, and scene lighting. Founded in 1973 and headquartered in Eagleville, Pennsylvania, Streamlight traces its origins to a NASA solar-simulator project that led to an early high-output handheld light, and it has grown into a global manufacturer serving law enforcement, military, firefighting, industrial, automotive, and outdoor users. That professional focus and long track record have made Streamlight a standard in duty lighting.

The lineup spans duty flashlights, weapon lights for pistols and long guns, compact EDC lights, and headlamps, lanterns, and scene lighting for work and rescue. Rechargeable and battery-fed models cover different charging and logistics needs across duty and field use.

Streamlight's professional heritage shows in how its lights are specified and built. The company helped develop the ANSI FL-1 standard, the rating system that lets buyers compare lumens, beam distance, runtime, and impact resistance across brands, so its own products are documented against those measures. For duty use, the practical selection points are runtime at a working output level, a beam pattern balancing reach and spill, and switching that operates under stress, along with the durability to survive being dropped or recoil-mounted to a firearm. Rechargeable duty platforms simplify charging logistics, while battery models allow instant swaps.

Carry a light in a dedicated flashlight case, pair a weapon light with an optic, and keep a backup from our EDC flashlights selection.
