Why We Like The Cosmo 350 Headlamp
The simplicity of the Cosmo 350 Headlamp makes it a go-to choice for runs, hikes, climbs, or nights when a storm cuts the power to our house. With multiple burn modes and night light options, we can choose the best option to light our way. We really like its Dual Fuel design which lets us run it on its rechargeable battery or from three AAAs.

The little light that could
I bought this headlamp for a last-minute climbing trip since my usual gear was in storage, and I didn't have high expectations given its small size. However, I was pleasantly surprised by its performance. It provides enough light to make me feel safe, and it's both lightweight and comfortable to wear. Paired with the battery pack, the Cosmo offers decent battery life—not the best, but definitely better than I anticipated for the price. I'll definitely be adding this to my pack for future trips.

Let me down when needed
Timed a 9 hour hike wrong and ended up doing the last two hours in the dark. Was severely underpowered. I’ve used this before for cooking and hanging around camp and its fine, but not up to the job of hiking at night which is why I have it. Bought this to replace my old reVolt and wish they still made that model because it worked much better.

Simple and Bright
The Cosmo is one of the easiest headlamps to operate. Simply press the button for on and off and the other for color and level. Plenty of light and a small package. This is a go to headlamp for 99% of activities.

Awesome Cosmo 350 Head Lamp!
My old head lamp was beyond old and couldn't recharge anymore so I bought this head lamp as my last one was from Black Diamond. It's amazing! The area it lights is amazing! I love the idea of rechargeable batteries so I'll try to get them soon. Love this head lamp!

The brightness is unreal! Weighs next to nothing, comfortable strap and red light for night vision is perfect. I did not get the rechargeable battery oack as yet but planning to at some point.

Perfect Package
Got the light and rechargeable battery. Like the ease of controlling the light on/off, intensity, mode, and color. The new open to the elements battery compartment makes opening the case much easier then previous models. Haven't tested battery life yet.
