Alright, this Streamlight Stinger 2020 is seriously impressive - we're talking professional-grade lighting here! It pumps out a massive 2000 lumens on high mode, with a beam that reaches over 1000 feet (315 meters). The intensity selector switch lets you choose between high, medium, and low settings depending on your needs - no cycling through modes you don't want. High gives you 2 hours of blinding light, medium 850 lumens for 4 hours, low 100 lumens for 24 hours, plus there's a strobe function for emergencies. The aluminum alloy body is tough as nails with an anti-roll design and textured grip that feels secure even with wet hands. It's IPX7 rated waterproof (can handle 1 meter submersion) and impact resistant from 2 meters. The rechargeable SL-B26 battery pack offers multiple charging options - use the included 120V AC/12V DC charger, USB charging, or even a battery bank charger. The BOROFLOAT glass lens is corrosion-resistant and crystal clear. Whether you're in law enforcement, security, construction, emergency services, or just need a seriously reliable flashlight for outdoor adventures, this Stinger delivers professional performance that puts cheap flashlights to shame. The intuitive controls and multiple lighting options make it versatile for any situation where you need dependable, powerful illumination.
