Sharing the same architecture as the Remix Rechargeable, Remix Plus builds upon the proven Remix headlamp. Dimmable LEDs, greater output and longer burn time are possible due in part to the rear mounted battery pack. The battery pack also serves as a platform for flashing rear lights. Four AAA batteries (included) provide power while the head rotates back to protect the power button during storage and transport. Light output: 165 lumensRun Time: 160 hoursWeight: 5.6oz. with batteries
