This BD headlamp is a steal at STP. For a similar Petzl or Princeton Tec you'll pay 2-4x what this one costs. Changing batteries is easy, and the headlamp has multiple intensity and directional adjustments. I've used it camping, hiking, and even for some work around the house when I had to kill p...

    Very bright and decent battery life at this price. Kinda complicated button sequence but instructions are clear. Interesting that the lower powered LED has a shorter battery life than the brighter LED. Either it's an anomaly or a mistake, but doesn't much matter. Should be sufficient battery life to negate needing to carry spare batteries on a multi-night trek.

    Bought this one as a simpler backup option to my awesome Storm. Works great, Black Diamond and Sierra trading Post deliver once again.

    Good price on two that work great for what they are intended…two hands can be used at the campsite or at home. PLUS in an emergency situation at home or when trekking, great to have two hands handy. Finally, as a "I-canoe-in-the-Boundary- Waters-trekke," (multiple treks) it is nice to know that IF we had to paddle at night, (never recommend in the wilderness), good to have this mounted on the hat (I have velcro sewn on my hat so the light can't fall off) as both hands are needed to paddle.

    We haven't taken this headlamp out yet into the wilderness (it's 7 degrees tonight!), but it so far operates well and is very bright. There are multiple settings on the light itself, which allow for a super bright beam, a combination of white led lights, and a red light. The strap is good and the design is compact but seemingly durable. The tricky part is figuring out how to change modes. At first, we could only get the super-bright main beam. With some button poking, we discovered it did successfully change modes, but it's a little weird to get used to. I haven't played around with it too much, so I think it will be fine once I get the hang of it, but that's why I give it 4 starts instead of 5. The quality of the light is fantastic. I also haven't really checked out battery life yet, but I suspect that even a bright LED will be far more conservative using juice than the old incandescent bulb headlamp that this is replacing. That one, though no longer the most powerful tech, was waterproof--which this one is not, so the old one will probably get to stick around in the box-o-camping supplies for special uses.

    Strong enough for night hikes and the read light is perfect for activities that require map reading without night blindness
