Don’t Buy This Headlamp
1 year ago
The battery pack is secured by a thin and flimsy plastic latch. It’s s terrible design. I can’t believe BD signed-off on it. It broke in my hands, in my kitchen, the very first time I tried to put batteries in it. I’m very glad it didn’t break out in the mountains somewhere where it would actually matter. I’m sure the actual light is adequate, but the battery compartment latch design is a fatal flaw, and a deal-breaker. You have been warned.

Durable, Effective, Heavy

Durable and comfortable headlamp that runs on 3 AAA batteries. At nearly 5 oz with batteries it is not "lightweight." BD made the right decision by putting the battery pack in the rear to balance the felt weight and minimize neck strain. I also like how it is rated IP67 (dust and waterproof to 1 meter). Decent battery life on the low setting. You can run it with the BD 1800 rechargeable battery pack. Overall, I like it. I also have the Petzl Swift which has similar properties but is significantly lighter at 3.5 oz or 100 g. Still on the fence as to what I prefer. But I am happy with the purchase.

Touch/capacitive controls don't belong on headlamp
1 year ago
I should have done more research. I've made the mistake of buying a cheaper headlamp with capacitive controls before, and it was infuriatingly inconsistent in it's ability to control. This headlamp is no differnt. The tap control of touching both sides to toggle modes often results in no effect but then when I go to adjust the angle by touching one finger to the top and one to the bottom if my finger brushes just one corner it will react as if the 2 sided tap occured. I can tap both sides 10 times and nothing, then do the same thing 5 seconds later and it works but often detects it again upon release and goes back to its default state. Capacitive buttons need to be very obvious about finger placement especially on something meant to be used outdoors. It also seems to not even need touching and will often activate if you just place two fingers about 1/4 inch from both sides. Maybe this is intended in order to deal with gloves? But then it should have a delay so that you don't accidentally cycle modes rapidly back and forth, because like I mentioned before, it often swaps modes and then immediately swaps back within less than a second as if it was activated twice. Seems like some very low level oversights, unless mine Is just defective. Physical buttons seem like a no brianer, I never understand companies that try to implement touch controls in places they only hurt function. Seems like marketing teams have too much control over design choices.

headlamp with much to be desired
1 year ago
Disappointed in the quality and functionality of the product. The clasp holding the batteries breaks easily and the inability to use both lamps at the same time leave much to be desired. A good headlamp should focus a beam of light ahead of you, this one only provides light in your general vicinity. The lumens appear to be over-stated and the head-lamp lacks features. I would consider this more of a weekend camping headlamp than something useful while on a trail or mountain adventure. For the amount of money this product costs, I expect more.

Best investment for camping at night
1 year ago
We got to the campsite in the rain and pitch dark at night. The headlamp freed up a hand from holding a flashlight so I could focus on setting up the tent in the dark. It's nice and bright and it can also dim very low soft light. Very simple button to go through the light modes. Just be mindful and try not to blind your friend when you look directly at your friend's face. Unless you are interrogating them on who stole the cookie from the cookie jar.

Great light, poorly made

I’ve never had a headlamp break faster than this. The clasp that keeps the battery casing close snapped after two trips. Before the break it was a great light, sort of useless now…

Not reliable

I bought a few of these because the first one I got felt so pefect. Then one fell. And the battery spilled all over. I was able to manage and not leave acid behind. I thought I didn’t secure the battery compartment well. At home I experimented with all of them. The batteries fell out after a few tests from all of them. One even broke the latch mechanism. Do not buy. Common black diamond!! This is dangerous.

Fantastic headlamp!
3 years ago
I really like this headlamp. It is simple to use and bright. The way the weight is balanced out by putting the batteries in the back is so nice. Just days after receiving my new Onsight 375, I used it during a nighttime river recovery. Unfortunately, I dropped it into the frigid river. Fortunately, the light stayed on and after the work was done, I was able to fish it out with a pole. I stuck it back on my helmet and the headlamp never missed a beat after spending an hour so several feet down in icy river water. Super impressed!

Works well

I’ve used this once. The light output is decent; however I was expecting more illumination as it was advertised for nighttime climbing. I would like to see a stronger intensity light for finding holds, bolts and features that are further away for route finding. The back battery pack is fairly heavy while the front bulbs are light. This makes for an imbalanced feeling. Adjusting intensity is easy enough. The battery life is short. The clamps to open the battery cover seem weak. I can’t speak for its robustness or longevity.
