Energy efficient lighting

Lighting typically accounts for up to 35% of your total power bill. There are steps you can take to reduce lighting costs at your workplace.

No cost options

Switch off

Turn off internal lighting after hours, especially energy intensive display lighting.


Regularly clean lights and light fittings. Dirt and dust can reduce light output significantly.

Low cost options


Install motion sensors on outside lights and lights in seldom-used areas, such as meeting rooms, bathrooms and storage rooms.

Efficient bulbs

Replace inefficient lamps with efficient options such as linear and compact fluorescent lamps (CFLs) or T5s. They use less electricity and last longer.

Separate lighting

Divide large blocks of lighting into separate switches, so areas can be turned off when not needed.


Measure lighting levels and reduce lighting in over-lit spaces. Make the most of natural light. Timers Use a timer for external and security lighting to automatically turn on at dusk and off at dawn.
