Black Diamond Astro 300 Headlamp

The Astro 300 from Black Diamond is a capable, no-fuss headlamp for climbers, hikers, and campers who want reliable output without a complicated feature set. A single-switch interface steps through 300-lumen maximum, 150-lumen medium, and 6-lumen low modes, plus a strobe function, all from one button. Brightness Memory retains your last-used setting so the light comes on at the right level without cycling through maximum output in the middle of the night. Digital lockout prevents accidental activation in a pack or pocket. IPX4-rated waterproofing handles rain and sleet from any direction, and power comes from three AAA alkaline batteries (included) or the optional rechargeable BD 1500 lithium-ion battery.
