The Prêt a Racket is a solar-powered outdoor lamp and can burn for approximately 6 hours at a time.
It switches on automatically as soon as it gets dark. After 6 hours, the lamp also switches itself off again by an integrated timer. The lamp can then be switched on again manually by pulling the red cord twice briefly, to extend the burning hours.
Place the lamp in a place with a lot of direct sunlight, so that the lamp can be properly charged during the day. If there is little sun during the day, the lamp will burn less when it gets dark.
