    by fromCosmo Headlamp is awesom I use this headlamp in the early morning hours around my dogs and horse. It is lightweight and I like the ability to dim the light to the brightness level that I need.

    by fromWorks well, although a little fiddly This headlamp works very well and comes in very handy in many situations. The only complaint I have is that it can be somewhat fiddly to get it set to the right level of light that you want. You have to hold the button in while the lamp dims to the level you want it at. Or if you want different settings (red or flashing) you have to click it at just the right timing or it just turns on and then off. My other Petzl headlamp is much easier to set how you want it.

    by fromGreat new headlamp! This is a marked improvement on past headlamps. Go ahead and upgrade if you're considering this! Good battery life, and the red lighting for climbing out of a tent and not waking up your neighbors is awesome.

    by fromNice Light. Good light output I have been using the light for a while. Good light output and long battery life. Great for travel, car camping and backpacking. I got 2 more for my 2 kids when I found these on sale at REI. I think most of these lights with LED are all about the same. Light output at max (manufactured rated at 70 lumens) has plenty of light output. Unless you have specific needs for more light, these are more than adequate.

    by fromGreat value for a head lamp I bought two of these headlights for our Boy Scout Jamboree trip. I really like this Cosmo model. It is very comfortable to wear for long periods, and for the price it has high end features. My favorite feature is the continuous dimming on the main LED. My only nitpick--and it is a minor one--is that the different modes for this product are not intuitive. The instructions were well written, but let's face it, no one brings the instructions on a camp out. It only took me a couple of uses to get it down, so overall I think this is a well executed headlight design. I can definitely recommend the Cosmo headlamp!

    by fromVery nice Replaced a Princeton Tech Fuel with this lamp. Had my Fuel for five or six years, or more, and it was awesome...til I broke it. However, the one thing I really love about the Cosmo is the red light. Around camp, whether I'm backpacking or car camping, the red lamp is perfect. For the killer white light, I don't do any night hiking or backpacking, but if I did, I'd be happy to have this lamp. Overall, I'm very happy. I didn't give it 5 stars cause I don't give anything a perfect score. Nothing's perfect. This is a 4.5.
