How bright is the Astro 300 and what can I expect from its beam?

The Astro 300 produces up to 300 lumens, offering a usable mix of flood and spot illumination suitable for close-up tasks and short-range trail navigation. Dimmable control helps you choose between full output for clear distance or reduced output to extend battery life and preserve night vision.
