Rechargeable LED (light emitting diode) headlamp. Features a low-profile, compact design with 5 light modes. Light modes include turbo, high, medium, low, and red mode. Turbo mode is designed to give short bursts of power when it is needed most. After 30 seconds, the light will return to the previously used mode to prevent the light from overheating and protect the battery. Red light mode conserves night vision. Durable ABS and aluminum construction is also water resistant (IPX4). Features a comfortable strap design that is fully adjustable for a perfect fit, and an easy tilt light to get the best angle for any lighting application. Flex-Power technology uses the included rechargeable battery with included micro-USB (Universal Serial Bus) charging cable, or can be swapped out for (2) CR123A batteries. Use of the CR123A batteries will slightly reduce run times.
