Ceiling flush-mounted photocell switches


Download Installation Guide


This 'Re-set' version switches the lights off when there is sufficient ambient light but requires the wall switch to be operated in order to switch on. In this way the lights only switch on when demanded.

For flush mounting through suspended or plasterboard ceilings.
Complete with 2m cable for quick and easy installation.

  • Built-in differential ensures the artificial lights do not affect the photocell.
  • Built-in time delay of 1 minute avoids unnecessary switching.
