The NU25 is back lighter and more powerful than before with a dual beam spotlight and floodlight for a combined 400-lumen max that can reach out to 70 yards. Equipped with an upgraded unibody optical lens system switch freely between a primary spot LED, offering three brightness settings, to the flood LED for even wide illumination, ideal for close-up tasks and reading. Alternatively, switch to the dual red auxiliary LEDs and protect your night vision or long-lasting signal light. The NU25 is rated IP66 water resistant, features a bold new aerodynamic unibody design that efficiently dissipates heat, and looks stylish to boot.
