A method of providing power for non-lighting related loads in which operate during daylight hours when a lighting dedicated switched mains network (220) is switched off is described. The method comprises charging a battery (240) at night from the mains network when the luminaire is switched on so that the energy/power stored in the battery can be used during the day. A luminaire (200) comprises a luminaire light engine (210) connected the mains network (220), an AC/DC down converter (230) also connected to the mains supply so that the battery (240) is charged during the hours of darkness. The battery (240) is connected to provide power to a DC non-lighting related load (250) which is operable both during daylight hours and hours of darkness. |
