Streamlight Flashlights

Why Streamlight Stands Apart in the Flashlight Category

Streamlight has spent more than 50 years designing and manufacturing flashlights built to serve professionals who simply cannot afford a light to fail them. Based in Eagleville, PA, Streamlight has designed, manufactured, and marketed high-quality, durable flashlights for the specialized needs of professionals and consumers alike, offering a broad array of lights for law enforcement, military, firefighting, industrial, automotive, and outdoor applications. Within the broader flashlights category, Streamlight has carved out a reputation for pairing raw output with purpose-built engineering — the result of decades of hands-on field experience.

Flagship Product Lines

Streamlight's flashlight lineup is organized around clearly defined use cases, making it straightforward to find the right tool for the job.

• ProTac Series: Tactical models like the ProTac series offer bright output, strobe functions, and weapon-mount options, making them a go-to for law enforcement and security professionals. The ProTac 2.0 HP uses Streamlight's TEN-TAP® programmable switching system to control light settings via the tailcap switch.
• Stinger Series: Introduced in 1994, the Stinger series has grown to include 15 variations, evolving into a rechargeable workhorse for vehicle patrol and general utility. The anti-roll body design, rectangular grip, and intuitive low-medium-high mode selector give operators ultimate lighting control.
• Strion Series: The Strion 2020 is one of seven in the Strion lineup, offering just the right balance of power for indoor or outdoor use, plus a strobe mode. It strikes the ideal balance between compact form factor and serious lumen output.
• Sidewinder Series: The Sidewinder X is a high-output, right-angle light with a 185-degree tilting head, flat base, and the ability to use either AA alkaline or CR123 batteries. Though designed for the military, it adapts easily for civilian use and offers various colored LED lamps.
• Nano Light II: Measuring just 2.2 inches and weighing a mere 0.6 ounces, the Nano Light II is constructed from machined aircraft-grade aluminum with an anodized finish, and its white LED is impervious to shock with a 50,000-hour lifetime.

Signature Technologies

What separates Streamlight flashlights from the competition isn't just lumen counts — it's the engineering behind the light. Many models feature C4® LED technology, impervious to shock with a 50,000-hour lifetime, and a TIR optic that produces a concentrated beam with optimum peripheral illumination.

TEN-TAP® Programming lets users reprogram a light from the standard default option with just a few quick taps of the switch, choosing from three user-selectable programs — for example, High/Strobe/Low (factory default), High Only, and Low/High. This flexibility means a single flashlight can serve surveillance, search-and-rescue, and everyday carry duties without compromise.

On the rechargeability front, battery options include USB rechargeable, lithium-ion, alkaline, or CR123A batteries, and many multi-fuel models accept both proprietary rechargeable packs and standard disposable cells — so you're never left dark in the field. Most Streamlight models are IPX7 or IPX8 waterproof rated and constructed with anodized aluminum, ensuring durability in rain, mud, and harsh industrial environments.
