Reviewed by William • Updated May 2026 $50

The Black Diamond Spot 400 is the headlamp most experienced AT hikers recommend to beginners and keep using themselves. Four hundred lumens on three AAA batteries. IPX8 waterproof rated to 1.1 meters. Separate spot and flood modes with a red night-vision mode that preserves dark adaptation in camp. At $50 with a lifetime warranty from a brand with 20 years of headlamp credibility, it's one of the easiest headlamp recommendations to make in this category.

Common Questions

Is the Black Diamond Spot 400 rechargeable?
The standard Spot 400 uses 3 AAA batteries. Black Diamond also makes the Spot 400-R — the USB-C rechargeable version at a slightly higher price. The battery version is better for backpacking where USB charging may not be reliable; the rechargeable is better for car camping.
How long does the Black Diamond Spot 400 last on batteries?
At maximum 400 lumens: approximately 4 hours. At medium brightness (100-150 lumens): 40+ hours. Most hikers use medium brightness for camp navigation and save maximum for technical night trail use. Use lithium AAA batteries for cold weather.
