Black Diamond is enhancing its Storm headlamp lineup with the new R-Series lamps. This particular Storm 500-R Headlamp is a high-lumen and multi-mode lamp that gives us the power to fully illuminate our nights with nine different lighting modes and the potential for 5H of charge time at the highest setting. We really like that the Repreve headband stops that uncomfortable, hair-pulling sensation we often get with cheaper headlamps.
