Headlamp features a removable design that lets you quickly remove the headlamp & use it as a flashlight, all while the base of the headlamp stays lit, leaving two light sources. A magnet on the headlamp allows you to secure it to any metal surface once removed. Straps are adjustable to provide a secure yet comfortable fit. Battery-efficient design uses the four included AAA batteries & provides up to 6 hours of use.
