The Black Diamond Spot 400 has 400 lumens of power, now housed in a smaller, more efficient design. 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 Spot 400 is also Dual-Fuel compatible, allowing you to power the light with either the rechargeable BD 1500 Li-ion battery or three standard AAA batteries. The light’s updated optical efficiency not only provides brighter light with more peak intensity, but also saves battery life that’s easily trackable 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. Plus, the Spot’s PowerTap Technology makes for instant brightness adjustment settings.
