Overnight relay races like the Tuna Run 200 (www.tunarun200.com) are all the rage. An essential piece of gear for nighttime running is a headlamp. The Black Diamond Cosmo is a versatile headlamp with the size and weight of a backup light. Two single-power LEDs and a strong double-power LED cover short- and long-range viewing with an impressive 55 lumens on max setting. The Cosmo uses three AAA batteries and includes a single switch that activates three modes plus dimming. Its unique design protects it against splashed or sprayed water from any angle.
