Petzl invented the modern headlamp back in 1972 and has been upgrading the technology since. Their newest offering, the PETZL TIKKA PLUS 2 ($39.95, petzl.com), is a light (2.5oz), tough, and super-smart headlamp that builds on the popular Tikka platform. New additions include: a brighter (50 lumens), high-output white LED; a red LED, for night-vision preservation; a battery-charge indicator; and an easy-open housing, for quick battery changes. To fl ip LED modes (white or red), simply depress the top-mounted power button for two seconds; when you power up, the lamp defaults to the last mode used.
