The compact light operates on a single AAA battery-however they are not included. There are two brightness settings. Low produces 8 lumens and has a 15 hour battery life. High puts out 25 lumens with an 8.5 hour battery life. The adjustable elastic headband has a pouch built into it to store an extra battery.
