Black Diamond's ultra-thin, well balanced USB-rechargeable headlamp that also runs on standard AAA batteries, the 275-lumen Black Diamond Sprinter 275 is purpose-built for longer distance pre-dawn/post-sunset runs that require the reassurance of longer battery life. The light’s updated optical efficiency provides a balanced beam with brighter light, and you can easily track battery life with a six-setting, three-LED batter meter. The Brightness Memory feature allows you to turn the light on and off at a chosen brightness without reverting back to a default setting, and the Sprinter 275’s PowerTap Technology makes for instant brightness adjustment settings. The light’s perforated elastic headband is designed for improved breathability while running, excellent front/back balance and a red taillight strobe in the rear adds visibility in urban areas but can be turned off when you’re on the trails. Now running on the new modular BD 1800 rechargeable battery, the Sprinter 275 is modular, accepting either the rechargeable battery or standard AAA alkalines. In addition, a stormproof design keeps the Sprinter 275 going strong in any weather with regulation for constant illumination throughout the battery life.
