The NSR-9854XL USB Rechargeable Multi-Function Tactical Dual-Light™ Flashlight uses an LED rated at 850 lumens working in conjunction with a high-efficiency deep parabolic reflector to create a usable beam of light rated at 280 meters. A 200-lumen unfocused floodlight is integrated into the housing which is perfect for close-up illumination. Both the flashlight and the floodlight can be turned on at the same time for maximum safety and versatility. The NSR-9854XL has a unique tail-switch that operates both the flashlight and floodlight in one configuration. The upper portion of the switch operates the flashlight that provides either momentary or constant-on functionality with high, medium or low-brightness settings as well as a disorienting strobe and the lower portion of the switch operates a downward facing floodlight. The housing, tail-cap, and bezel are made from aircraft-grade 6061-T6 aluminum with a Type III hard-anodized finish. Power comes from a rechargeable Lithium-ion battery. (Not compatible with CR123-style rechargeable batteries.)
This has been a great duty light, and now is my primary flashlight for hunting for things around the house, camping, hikes, etc.. Throwing a wide beam at the ground to see where I'm going while having a forward beam is great!
Using the momentary switch for low-light ops, from the range to actual searches for suspects was perfect. When a buddy forgot his flashlight as we entered a dark construction site I let him borrow my "club" flashlight (3 "C" Cell flashlight), the Nightstick stays with me.
