Why We Like The Astro 300-R Headlamp

The Black Diamond skips some of the bells and whistles to provide a reliable light source that we are always happy to have in our pack. We always slip this headlamp into our pack before hitting the trail so that we know we have 300 lumens of light to help us get back to the trailhead in the event we have to stay outside longer than we planned.


  • Lightweight headlamp designed to come along on any adventure
  • 300 lumens makes it easy to see the trail or around camp
  • Multiple settings let you customize your lighting
  • Rechargeable lithium-ion battery offers reliable power
  • Recycled elastic strap locks in a secure and reliable fit
  • StormProof rating fights back against blowing snow and rain
  • Digital lock prevents the battery draining inside of a pack
  • Item #BLDZ9I7

Compact, light, and bright headlamp

Well built, light-weight headlamp that has a powerful beam that you can adjust by just holding the button which fades the brightness down and up to get the exact level desired. Built in batter lasts a long time. Two thumbs up!

Good basic unit

My headlamp is very bright and I appreciate the dimmer switch feature and the rechargeable lithium battery. It would have been nice to have the red light feature for night work, but that feature doesn't come with this model. Overall satisfied with my purchase.

Lightweight, practical

The adjustment settings are easy to use and give lots of good options, it’s lightweight, and brighter than headlamps I’ve used in the past.

not only is this lamp very easy to use, but this lamp is BRIGHT. I use this headlamp for my evening runs, early morning hikes and whatever other activities that require a good quality headlamp. I love it.

Iota was much better

Too heavy and big. I preferred the Iota which is no longer available.

The last light wasn't as waterproof as I would have liked, I'll give this one a shot and update my review, but so far so good....

Love me rechargeable head lamp

I recently bought the headlamp online. Delivery was super quick. I love that it is rechargeable, so I don't need to use batteries! It also has a great dimming feature! And it is beautiful! The only thing I'm missing is a red light, that I didn't noticed that the headlamp doesn't have when I bought it. But it is still a great product!
