The Sprinter 500 is purpose-built to handle everything from early morning urban runs to all night mountain running adventures. Ultra-thin and well balanced, the Sprinter 500 features nearly twice the lumen output of previous versions, emitting 500 lumens on the light’s brightest setting. Providing maximum power flexibility for runners on the move, the Sprinter is Dual-Fuel compatible and can be powered with either our rechargeable BD 1800 Lithium-ion battery which is included when purchased or it can run off three AAA alkaline batteries as well. The single front lens has an extremely smooth universal beam that minimizes hot spots and eliminates harsh transitions on the trail. It includes Black Diamond's intuitive single button interface for easy on/off actuation, PowerTap™ Technology for quick on the fly brightness adjustment, and variable dimming for fine tune adjustment of your brightness setting. The Sprinter has a lightweight perforated elastic headband for increased breathability and the top strap is quickly added or removed based upon user preferences. With reflective logos and a rear red flasher, it will help to keep you visible on the road and on the trail.
