Small enough to pack just in case, but bright enough to illuminate unexpected rappels and dark trails, the Astro 250 features a more ergonomic compact body and a lower profile for better balance. Plus, the updated optical efficiency not only delivers brighter light at 250 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.
