Streamlight 78101 Stinger 2020 Black Anodized Aluminum LED Flashlight - 100/850/2000 Lumens

The Streamlight Stinger 2020 is a rechargeable tactical flashlight built for law enforcement, search and rescue, security, and serious outdoors work. This 2000-lumen LED light delivers three output levels plus strobe mode, so you can match brightness to your task—whether that's scanning a vast area, maintaining battery life on patrol, or signaling for help. The dual independent switches (one on the head, one on the tail) let you select high, medium, or low mode directly without cycling through settings, keeping you focused on the job at hand.

Built tough for real conditions, the Stinger 2020 features a corrosion-resistant gasket-sealed design, borofloat glass lens, and black anodized aluminum body with an anti-roll design and textured grip. It's rated IPX7 waterproof and survives a 2-meter impact test—meaning it'll handle field use, vehicle mounts, and the occasional drop. The ergonomic form factor fits naturally in your hand on long shifts.

Power comes from two SL-B26 protected lithium-ion battery packs, both USB rechargeable. Use the existing Stinger chargers, a USB cord, or any lithium-ion bank charger to keep them topped up. High mode runs for 2 hours and throws a 315-meter beam; medium delivers 850 lumens for 4 hours of operation; low stretches to 24 hours on 100 lumens. The strobe mode runs for 3.25 hours and serves for disorientation or signaling. At 7.67 inches and 12.3 ounces, it's compact enough for duty carry but bright enough for serious illumination work.

Frequently Asked Questions

Is the Stinger 2020 rechargeable?

Yes. The flashlight uses two SL-B26 protected lithium-ion battery packs that are USB rechargeable. You can charge them using the existing Stinger chargers, a USB cord, or a standard lithium-ion bank charger.

Can I use this flashlight in wet conditions?

Absolutely. The Stinger 2020 is rated IPX7 waterproof and features a gasket-sealed design with borofloat glass, making it suitable for field work in rain, near water, and other damp environments.

What's the difference between the three brightness modes?

High mode produces 2000 lumens with a 315-meter beam distance and runs for 2 hours. Medium delivers 850 lumens with a 200-meter beam for 4 hours of runtime. Low produces 100 lumens with a 70-meter beam and extends to 24 hours of operation, making it ideal for extended patrols or when you need to conserve battery.

What do the independent head and tail switches do?

The dual switches allow you to directly select your desired brightness level (high, medium, or low) without cycling through modes. This "set and forget it" design means faster, intuitive operation in the field.
