Danlers CEFL PH Ceiling Photocell Switch (2m lead wire)

A Ceiling Mounted Photocell Switch from Danlers that fits flush into plasterboard or suspended ceilings. This unit switches lights off when there is sufficient ambient light but require the wall switch to be operated in order to switch on. In this way the lights only switch on when they are demanded. A built in time delay of 1 minute avoids unnecessary switching.
