"Nathan® Neutron Fire R: The Nathan® Neutron Fire R is a lightweight running headlamp designed for runners who train in low-light conditions - whether on roads, trails, or paths at night or before sunrise. It delivers 115 lumens of white LED spotlight to illuminate the path ahead, giving you solid visibility without the bulk of heavier headlamps. Two side-mounted RGB strobes add red, green, or blue light options that work alongside the main beam to increase your visibility from multiple angles, which is especially useful if you run near vehicle traffic and need to be seen from different directions.The headlamp's lightweight, low-profile design sits close to your head and stays stable through your entire run without adding noticeable weight. Power comes from replaceable AAA batteries, so you're never stuck waiting for a charge - just swap them out and you're ready for your next early-morning or evening run. The RGB strobe functionality sets this headlamp apart from basic single-mode options, giving you the flexibility to switch between colors based on conditions or personal preference. Available in five colors, the Neutron Fire R adds both function and personality to your nighttime running routine.Why Our Fit Experts Love It""I grabbed the Neutron Fire R for a pre-dawn run and the 115-lumen spotlight gave me solid visibility on the road.
