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 comes in three exciting colors, and offers over 115 lumens of clean, eye-pleasing light. A powerful, customized LED disperses the perfect Run-Right Light for runners, blanketing both distance and proximity, creating a less tenuous night running surface. There are five lighting modes - low, medium, high, sprint, & strobe - Burn Time: 30+ hours. Change light settings touch-free with Nebula Fire's Run Wave technology - no more fumbling for buttons! The Nebula Fire also communicates your presence to drivers via Auto Strobe, 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 adjust-ability of the headlamp allows you to easily find the perfect light angle for the trail or road.
