Why We Like The Black Diamond Astro 300 Headlamp
With a lineup as versatile as Black Diamond's, it's no surprise they'd design a headlamp that plays in as many sports as we do. The Astro 300 Headlamp is a simple, lightweight, and ultra-versatile light source for early-morning tours, late-night climbs, and every camping trip in between. Three brightness settings allow us to limit sight damage or maximize visibility for the adventure ahead.

So far, so good
I'm glad this headlamp doesn't come with a lot of bells and whistles. On and Off. That is what I need when I am fumbling around in the dark on my way to the bathroom in the middle of the night.

A couple tiny complaints
You don't even mention how to unlock the light in the quick start guide, a little TOO minimalistic . Also why. a single video covering all layouts rather than separate ones, cutting corners and an annoying trend. Good light, just my nitpicky criticisms

Perfect for camping
Bought these for my kids before they went to an overnight mountain biking camp, and they were perfect!

Disappointing - Toggling Between Modes Is Probelma
Disappointing. It is difficult to toggle between modes with the single button. When I attempted to lock the lamp it first strobes, then turns off, then when attempting to turn in back on it gets stuck in strobe mode. The only solution I found was to remove the batteries to reset the lamp.

Reliable Gear for Every Adventure
I’ve been using the RockLock Screwgate Carabiner, Distance LT 1100 Headlamp, 18mm Nylon Runners, and Astro 300 Headlamp, and I must say, they are top-notch! The RockLock carabiner is secure and easy to handle, making it perfect for climbing. The Distance LT 1100 Headlamp is impressively bright, ideal for night hikes, and has a great battery life. The 18mm Nylon Runners are durable and versatile, holding up well under various conditions. The Astro 300 Headlamp is compact yet powerful, providing just the right amount of light for camping trips. Highly recommend all these products for any outdoor enthusiast!
