The first ever headlamp designed specifically for runners, Nebula Fire is packed with features that will make your night runs safer. This lightweight, multi-beam, rechargeable headlamp offers over 192 lumens of light. A powerful, customized LED disperses the perfect Run-Right Light for runners. There are five lighting modes: low, medium, high, sprint, & strobe with a maximum burn time of 25 hours. Change light settings touch-free with Nebula Fire's RunWave technology, no more fumbling for buttons! The Nebula Fire also communicates your presence to drivers via AutoStrobe, as the on-device sensor reacts to cars' headlights and triggers the safety strobe mode. The breathable mesh strap fits comfortably on your head, while the adjustability of the headlamp allows you to easily find the perfect light angle for the trail or road.
