The headlamp works as advertised, but the one I got had clearly been used and repackaged because the lamp itself was covered with scratches. I plan to keep it because it does work fine, but I'm a little upset about paying full price for a damaged product.

Cosmo 350 Lights Up My Night

Needed a lamp for local night excursions to walk the dog and find what she leaves behind. This lamp works perfectly. Red light is perfect for most tasks and especially handy when anyone walks with me so they aren’t blinded by my effervescence. White light is really only needed for the deep search and rescue. Easy to operate and is holding its battery life nicely.

Great For Astrophotography

Wanted a headlamp that has both white and red options but with the ability to lock the desired color. The lock option is great for my astrophotography so I don’t accidentally kill my eyes with white light but can switch to white for cleanup at the end of the night. Great product would recommend.

Rad Little Headlamp!

Awesome headlamp just to tuck away in a bag and was a lot brighter than other lamps this size! great light adjustability and super comfy.

So Far, So Good!

I bought this as a gift for my husband who often tries to hold/position a flashlight while working on projects in our house. Very, very bright. He is beyond happy with it!

Great Light

We already had one of these lights, and it was great, so when we needed another, we knew exactly which one we wanted to get. These lights work great, have lots of options and last long.

Good Headlamp

Quality, fit is good. We’ve already tried it out and love it!

The Red Light Is Terrible

This is the worst headlamp that I have ever used. Red lights are essential for camping so that you don't blind other people in your party. The red light in this headlamp is useless. You can't see your own hand in front of your face on either setting (high or low). To be fair, the white light is amazing and it lights everything up like heaven. But without a good red light, this headlight is useless in my opinion.

Very Nice Headlamp

Great headlamp. Got this for my son to use while hiking and hunting. Simple to use and light weight. Good bright light and red light worked nice as well! Love that this can use the rechargeable batteries to save some money in the long run!

Great Headlamp, But Rechargeable Battery Was Not Available

Where do you get the rechargeable battery? Not in the store. Too soon to rate it's performance.

Great Haedlamp

nice and bright> like the adjustable light feature. lith ion rechargeable is especially great on battery savings. 4-6 hours of run tends to eat into batteries. recharge is quick. had the 300 series but I'm going to love this one more.

Easy To Use

My first one survived two years of hard use during some western and midwest hunting trips, and everyday use around the farm. It still works just fine, but the plastic that connects to the headband cracked, so I had to tape it up in order for it to shine in front and not straight down. I bought a second one for primary use, and the taped one became my full time farm use. I like that you can switch between red and white light, and that dimming it is easy. It gets VERY dim, which is great for certain situations, but also gets very bright and shines a long way. I normally keep it somewhere in the middle of the range. For being less expensive than some of the premium options, I feel it is a good value.

Great Headlamp At A Good Price

Great headlamp at a good price. Plenty bright with good adjustable brightness, and a red lamp for use to not disturb others in the shelter in the dark (used this on the Appalachian Trail). And it has a lock-out feature so that it does not turn on accidentally while carrying in the pack. Uses normal AAA batteries.

Great Features Outdoorsman Headlight

As always black diamond makes good products super bright. Lightweight.
