The NEBO DUO Headlamp LED headtorch 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)

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. 

The light from the 250-lumen power LED has a spot beam distance of 122 meters. Its signature 2 strip C•O•B design fully illuminates your immediate area with its wide flood beam. 

The DUO Headlamp is tough, reliable, lightweight and completely shock-proof.
