You asked for it. The Bright As Day 1300S is the result of extended feedback from our community. By combining the existing 1300 lumen lamp head with our single cell battery, we have created the best lumen-to-weight ratio in our collection!

The headlamp has four brightness settings, SOS- and flash mode, and screw lock battery connection.

In addition, all our lamps come with extension cable allowing you to store the battery in a pocket or running vest ensuring an even lighter weight on the head, giving less strain on neck and shoulder. In colder temperatures we always recommend storing the battery close to your body to preserve its temperature and capacity.

The battery is latest generation lithium-ion cell (21700), giving an increase in capacity of over 25% compared with similar headlamps using 18650-type cells. This makes the Bright As Day 1300s a very popular choice for ultra runners and other athletes needing a powerful but light headlamp for short to medium duration activities.

Recommended for all intensive workouts where you need a strong lumen for a shorter amount of time. Ideal for running and cross-country skiing, and commuting on the bike.
