Bayco Nightstick USB558XL USB Tactical Flashlight 1100 Lumens White LED Black Anodized

The Nightstick USB558XL is a USB rechargeable tactical flashlight built by Bayco. It uses a white LED rated at 1100 lumens on high, with two lower constant-on output levels at 450 and 125 lumens, plus a momentary-on mode and a disorienting strobe, all controlled through a push-button tail cap switch.

The housing is precision-machined from 6061-T6 aluminum with a black anodized finish. It measures 5.90" overall with a 1.00" body diameter and a 1.20" head diameter, weighing 5.70 oz. An onboard rechargeable lithium-ion battery delivers up to 22 hours of runtime on the lowest setting and approximately 2 hours on full output, with a CR123 backup option for field use.

Rated IPX7 waterproof, the USB558XL is sealed against immersion and built to meet NFPA-1971-8.6 (2013) requirements for structural firefighting and emergency-service flashlights.
