QUAD Black. At a mere 96 grams and the ability to use lithium AAA batteries reducing the weight to just 82 grams , the Quad is easily the lightest headlamp in our Professional Series. Four Regulated Ultrabright LEDs illuminate even the darkest of outdoor conditions with a powerful and wide beam. Like the EOS, the Quad's housing is molecularly bonded together. Including the benefits of an O-ring seal, a battery meter, a separately molded battery compartment, and high-grade materials makes the Quad one of the best headlamps for working around camp,dark trail runs, and work spaces.
