Our lightest and most popular headlamp - Bright As Day 800 - delivers up to 800 actual lumens throughout the battery life, allowing you to keep going long after sunset. The headlamp features four brightness settings, an SOS mode, a flash mode, and a screw connection for the battery.
Additionally, all our lamps come with an extension cable allowing you to store the battery in a pocket or running vest, ensuring even lighter weight on the head, thus reducing strain on the neck and shoulders. In colder temperatures, we always recommend keeping the battery close to your body to preserve its temperature and capacity.
The battery is a next-generation lithium-ion cell (21700), offering over 25% more capacity compared to similar headlamps using 18650-type cells. This makes the Bright As Day 800 a very popular choice for ultra runners and other athletes who need a powerful yet lightweight headlamp with long battery life.
This lamp won the Hardrock 100, Western States 100 miles, and UTMB in 2022.
Need a spare battery for longer distances? Choose the ultra pack variant.
The Bright As Day 800 is water and dust resistant to IP67 standards and is the ideal choice for all outdoor activities at a slow or moderate pace, such as trail running, hiking, mountaineering, cycling, and more.
