The Petzl DUO S headlamp is a premiere hands-free lighting solution for rugged, tough environments. One of the standout features of the DUO line is the FACE2FACE technology, an auto-dimming option that automatically reduces the lumen output when one or more beams cross with each other. This provides comfort and safety when working in groups. The DUO provides five lighting modes to adapt to most work environments; BOOST mode can temporarily output a maximum power of 1100 lumens. Helmet mounting options are easy with mounting plates adaptable to the VERTEX and STRATO helmets or by using the helmets integrated headlamp clips. Rechargeable lithium ion batteries are quick to recharge and easy to remove and replace. Weighing only 13oz, the DUO is waterproof (up to 1 meter for 30 minutes in freshwater) with excellent crush and fall resistance. Click here for more.
