Voltax 7 LED Headlamp Water Resistant Battery powered Ultra bright high intensity LED light. Water resistant with LED lifetime of approx 100,000 Hrs. Adjustable headstrap keeps lamp from bouncing. Adjustable inclination. Takes 3X AAA 1.5V batteries This item is sealed in original packaging, There is no indication on the packaging, so I don't know if the batteries are already installed in the headlamp.
