Control the lights with motion and dusk sensors
Light sensors such as motion and dusk to dawn sensors switch lights on and off when they detect movement, or when it gets dark. Lighting control can reduce the electricity used by your lights by up to 40%.
Criteria for a recommendation from The Trust
The Trust recommends light sensors when a producer can demonstrate that the equipment saves energy. In addition, the power used by sensors themselves should be low. This not so much a quality issue as a requirement applying to their power-saving capacity. All sensors must be capable of being used with A-rated energy saving bulbs.
Lights switched on when movement detected, or when it gets dark
A motion sensor switches the lights on when there is someone in the room, and switches them off again when no movement has been detected for a while. This type of sensor is particularly suitable for stairways, passages, entrance halls, utility rooms, basements and carports.
A dusk to dawn sensor switches the lights on when it is dark.
You can reduce the electricity used by your lights by 20-40% by installing automatic lighting control, which means that your lights are only on when you need them.
The exact savings depend on several factors:
- How good you are at switching off lights already
- How big your home is
- How your home is furnished
Check that equipment can be used with A-rated energy saving bulbs
Always check before buying motion and dusk to dawn sensors that they can be used with A-rated and other energy saving bulbs. Usually you will be able to see this on the packaging, or ask in the store.
You can ruin A-rated bulbs if you control your lights with the wrong type of equipment.
