Jump to: Our Verdict / Features / Specifications

The Black Diamond Astro 300 is a simple and stripped down version of its bigger siblings, which still packs a lot of features, that make it a reliable and lightweight headtourch. 

Black Diamond says: 

The simple yet versatile one lens and one switch headlamp for the user that doesn’t need any bells or whistles and just wants a simple light. This user has the need to run the lamp on alkaline batteries if caught away from a power source for a long camping trip.

Our Verdict

The Black Diamond Astro 300 is a simple and stripped down version of its bigger siblings the Cosmo and Spot, however still packs in a lot of features for its size. The Duel fuel means that while supplied with AAA batteries it is also compatible with Black Diamonds Lithium Ion BD 1500 battery. 

With a multitude of  digital lock mode to prevent battery waist from accidently leaving it on, a high level of water resistance so no need to worry about the rain and brightness memory to keep your previous settings when you turn it back on. 

For its price point the Astro offers a lot and is a reliable lightweight headtorch, even if it doesn’t have some of the fancier features.
