摘要：
A method of activating at least one light source comprises reading (109) a value from a memory of a light device upon the light device being powered on. The value depends on how long the light device was continuously powered on before the light device was last powered off. The method further comprises determining (203) from the value whether the light device was continuously powered on for more than a predetermined period before the light device was last powered off and activating (213) the at least one light source in dependence on the determination.
