The Nebo Duo Headlamp is an all-powerful, hands-free lighting solution. The push button on/off button allows you to easily cycle through the Four light modes: one white LED (250 Lumens), 2 C.O.B strips (80 Lumens) or 2 Red C.O.B strips in steady or beacon mode. The red LED is a low-signature light, which ensures stealth in the dark, enhances night vision and makes reading in little to no light possible.
