Our award-winning, full-featured waterproof headlamp is now lighter, brighter, and smaller
For midweek dawn patrols, all-night approaches, or just big climbing objectives that push beyond daylight, the Black Diamond Spot 400 has 400 lumens of power, now housed in a smaller, more efficient design
With a new, compact body, the Spot 400 has been redesigned with a lower profile for better balance and is more ergonomic for added comfort. We've also updated the user interface by adding a second switch for easy lens mode selection
In addition, the updated optical efficiency not only provides brighter light with more peak intensity, but also saves battery life that you can now easily track with a six-setting, three-LED battery meter
The Spot 400 also offers peripheral lighting for close-range activities like sorting gear, cooking, or reading in camp and it sports an IPX8 waterproof housing
PowerTap™ Technology allows instant transitioning between full and dimmed power
