Versabrite™ is made of Xenoy/Polycarbonate material. The VersaBrite™ features a multiple position swivel head that allows you to point the bright beam in any direction. Due to its compact size and only .198 lbs. (.09 kg) of weight, the VersaBrite™ securely clips on to visors, caps and clothing. A head strap, Velcro and clip are available to keep hands free to work. It includes 2-AA cell alkaline batteries and is water resistant (not for diving applications). You break it, we replace it... forever.
