The UCO Air 150 Lumen Rechargeable LED Headlamp weighs in at just 1.6 ounces (with rechargeable battery), and is the perfect alternative to clunky, heavy headlamps. Lightweight and super-bright, it can be adjusted between zero and 150 lumens using the Infinity Dial Control, which also switches the light between white LED and red night vision mode.

The single-mode spotlight is powered by an internal rechargeable 170 mAh Li-Ion battery with a micro USB input (battery included; charging cable sold separately), with a running time of up to 48 minutes on high, 1.5 hours on medium, and five hours on low. The UCO Air 150 Lumen Rechargeable LED Headlamp is water-resistant to IPX4, measures 2.3 x .65 x 1.4 inches, and weighs 1.6 ounces (with battery). One-year manufacturer’s warranty.
