For nighttime adventures or emergency situations, no other headlamp provides the versatility and functionality of the 280 Lumen INOVA STS PowerSwitch Rechargeable Headlamp. This first ever rechargeable, dual-power, waterproof, two-color LED, multi-mode headlamp with Swipe-To-Shine® technology can run on its included Lithium Ion battery, or on three AAA batteries while the other recharges. That means no delays in waiting to use your light while it recharges. The waterproof, impact-resistant body of the PowerSwitch is designed around the innovative Swipe Pad. This Swipe-To-Shine (STS) technology allows you to activate the light, easily change between the white or red light, or change between the four modes: high, variable dim, strobe, or lock-out. When lock out mode is activated you don't have to worry that your light will turn on while being transported or stored.
