A light that easily fits into the pocket of your running shorts or vest and is virtually unnoticeable on your head, the Black Diamond Sprint 225 is purpose-built to power fast-paced morning runs or post-work trail sessions. With 225 lumens on the max setting with an average 2.5 hours of burn time, the lithium ion battery is rechargeable via USB, and the light’s storm proof IPX4 rating protects against rain and sleet from any angle. In addition, the Sprint 225 utilizes our updated optical efficiency, which provides brighter light with more peak intensity, plus now 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 the default setting, and the Sprint 225’s PowerTap™ Technology makes for instant brightness adjustment with the tap of your finger. Finally, the light’s vari-width headband is lightweight, packable, and stays comfortably in place on high-output runs.
