Small enough to bring just in case, but bright enough to light the way down unexpected rappels and dark trails, the Astro 300 features a compact body that is more ergonomic, and a lower profile for better balance. In addition, the updated optical efficiency provides brighter light at 300 lumens. The Astro's dimming and strobe modes let you customize the lighting to your needs, and the highly weather-resistant housing withstands rain and sleet from any angle.
