Abstract

A lighting device 1 comprises a body 3 having first and second fittings 5; one or more light sources 7 are positioned between the fittings 5; each fitting has power terminals 15 for receiving power from a primary power supply; a secondary power supply 17 is also provided via a secondary power terminal; an electronic circuit 19 controls power delivery from the power terminals 15 and secondary power supply 17 to the light sources 7; the power terminals 15-1b, 15-1a at the first fitting 5-1 are isolated from the electronic circuit 19 by an isolator 30. The secondary power supply 17 may be a backup battery which powers the light source if the primary power supply fails; the lighting device is preferably a replacement fluorescent tube type light device and the light sources may be light emitting diodes.
