Black Diamond Astro 300

Black Diamond Equipment says:
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 ergonomic with a low profile for better balance. In addition the updated optical efficiency provides brighter light at 300 lumens. New for the Astro is its Dual-Fuel compatibility allowing you to power the light with either the rechargeable BD 1500 Li-ion battery or three standard AAA batteries. 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.
