BD Black Diamond Spot 400 is an headlamp that has 400 lumens of power, now housed in a smaller, more efficient design, perfect for midweek dawn patrols, all-night approaches, or just big climbing objectives that push beyond daylight. With a compact body, the Spot 400 features a low profile for better balance and is more ergonomic for added comfort. The user interface also has a second switch for easy lens mode selection. The new Spot 400 is also Dual-Fuel compatible, allowing you to power the light with either the rechargeable BD 1500 Li-ion battery (not included) or three standard AAA batteries (included). 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 offers peripheral lighting for close-range activities like sorting gear, cooking, or reading in camp and it sports an IPX8 waterproof housing. The Brightness Memory feature allows you to turn the light on and off at a chosen brightness without reverting back to a default setting.
