The Astro 300 Headlamp is a simple yet highly versatile lighting solution. It can operate on either alkaline batteries or a rechargeable battery, offering great flexibility. With a powerful 300 - lumen output at its maximum setting, it emits a bright light that's perfect for any mountain adventure. It's also compact enough to serve as a reliable backup or for emergency situations. This headlamp features an ergonomic, low - profile housing that's stormproof, ensuring it can withstand rain and sleet from any angle. It comes with dimming and strobe modes, and a Brightness Memory function that remembers your last brightness setting, so you don't have to readjust every time. Key features include dual - fuel power options (three AAA Alkaline cells are included, and the rechargeable BD 1500 Li - ion battery and charger will be available soon), up to 300 lumens on max setting, full - strength, dimming and strobe settings, and a digital lockout to prevent accidental use. The maximum output is 300 Lumens (high), 150 Lumens (medium), and 6 Lumens (low), with beam ranges of 55m (high), 35m (medium), and 8m (low).

Using the Black Diamond Astro 300 Headlamp is easy. First, insert the batteries. You can use the included three AAA alkaline cells or the rechargeable BD 1500 Li - ion battery (which you need to buy separately). To turn on the light, press the power button. You can adjust the brightness by using the buttons to switch between full - strength, dimming, and strobe modes. The Brightness Memory feature will remember your last setting, so next time you turn it on, it'll be at the same brightness. When not in use, use the digital lockout feature to prevent it from accidentally turning on in your pack or pocket. For maintenance, keep the headlamp dry as it has an IPX4 water - resistance rating, which means it can handle some rain and sleet but avoid submerging it in water. If you're using the alkaline batteries, replace them when they run out. For the rechargeable battery, follow the charging instructions that come with the charger.
