Rated 5 out of 5 by from Simple Product that Gets the Job Done I don't think a headlamp should be a product with tons of bells and whistles, I just want it to light my way whenever I ask it to. This product is simple, and for the price, you get a very bright but fairly lightweight product. I think as both LED technology and lens shapes improve, this headlamp will no longer be the best, but for now, it's my go-to light. I wear it around my waist for nighttime trail runs. On a packaging note, the boxes BD is using suck. Good luck trying to get the headlamp back in the box the right way.

Rated 2 out of 5 by from Great for about one hour. After patiently waiting 8 long business days I was super excited to get this headlamp. Right out of the package it looks great and works great but then I took it out for a test drive. About 1.2 miles deep into a night hike on a trail in Boone it stops working after turning it off once. Supremely disappointed in the craftsmanship of this light. Although the quality of light is great if it craps out on you with no other available light, not good. Finding your way back by cellphone, bollocks to you black diamond. Refund ASAP.

Rated 5 out of 5 by from Great light. I bought this headlamp as a replacement for the BD Gizmo lamp that I managed to lose. It's quite a bit brighter. I use it for nighttime bike adventures around the city, and it is more than bright enough to get the job done. I've used it a couple times in the rain with no ill effects. I haven't dropped it yet to test durability, but the previous one, which is similar in desgin and construction other than the bulb configuration, survived quite a few drops and other torture tests, and kept shining.

Rated 4 out of 5 by from All you need...for life This is the best headlamp that I have bought for three main reasons. 1. The strap is the right size to fit anywhere, it isn't too small where the lamp flips up and down without expectancy, and it isn't like having a bandanna around your head. 2. The dimming is perfect when you don't want to blind anyone, plus you can angle your lamp any way you want. 3. Its a Black Diamond. You aren't skipping out on performance. It is basic, easy to use, and it works the way you need it to.

Rated 5 out of 5 by from Luminous! I love this headlamp. I use it mostly for backpacking and nordic skiing in the dark, so I need a lot of light. This light is super powerful. I love the adjustability of the beam. If you press and hold the light goes from lighter to darker. So far I've had the lamp for 9 months and haven't changed the batteries that it came with, even after heavy use. It's also super durable which is important. This light isn't bulky and stays on well. Love it!

Rated 4 out of 5 by from Quality headlamp I've owned a number of Black Diamond headlamps and they've never failed me. This is the second Cosmos I've purchased. I thru-hiked the AT with my first cosmos and loved it until I lost it. Decent enough battery life. Bright enough to hike at night with or switch modes and use for around camp. Keep a spare set of batteries on hand for safe measure. Great headlamp, especially for this price! LTM

Rated 5 out of 5 by from Bright and Light I've used this headlamp for everything from reading to night climbing. The two smaller LEDs are perfect for working around camp and reading and the bigger LED is bright enough to hike and climb by. The variability of the light output helps save battery when full power isn't needed. For the price, it can't be beat.

Rated 5 out of 5 by from This headlamp is magical It is nice and light and seems to be excellent quality. It's real, real neat! But some words of advice: when it first comes in the mail don't stare at it as you check how the settings work. Instead point it at your best bud and check the settings to make sure it's functioning.
