Black Diamond Astro 300

The simple and versatile Astro 300 headlamp with lens and switch is a true classic and features all the essential functions. When no power source is available, such as during a longer camping trip, the lamp can also be powered by alkaline batteries. Dual-Fuel: power supply with three AAA alkaline batteries (included) or the rechargeable lithium-ion battery and charger (sold separately) for maximum flexibility. Highest setting with 300 lumens. Adjustable options include maximum brightness, dimmed light, and strobe light. The memory mode saves the current brightness setting for the next use. IPX4 weatherproof: protected against rain and splashes from all directions. A digital lock mode prevents accidental activation in a backpack or pocket.
