Black Diamond Spot 400 Headlamp

The one to pick if you want a headlamp that runs on batteries sold at every gas station. It takes three AAAs, or Black Diamond's BD 1500 rechargeable pack if you buy it separately, so a long trip never depends on finding a charging port. Rated burn time stretches to around 200 hours on its lowest setting, while full power lasts closer to 2.5, and it has a red mode and a lock to stop it switching on in your pack. The spot beam is fairly tight and harsh for close camp work, and the button controls take a few nights to learn, but for a dependable, inexpensive light that you can keep running indefinitely, it is hard to beat.
