Installing energy efficient lighting systems throughout your building can help to drastically reduce the amount of energy consumed, lower your electricity bills, and reduce the carbon footprint of the building. When considering how to improve the energy performance of your buildings lighting system there are several things to look at.

Light bulbs

Traditional models of light bulbs, incandescent and halogen, are very energy inefficient in comparison to modern light emitting diodes (LED). LEDs turn on instantly at full brightness and have been produced to fit almost any light fittings. LEDs can turn about 70% of their energy into light compared to around 5% for incandescent and approximately 20-25% for halogens. LED linear/tube lighting can also be used to replace linear fluorescent lighting, which is commonly found in offices and industry places, as they are more energy efficient and environmentally friendly.

Sensors and timers

To ensure lights aren’t left on for hours in empty rooms, movement sensors or timers can be installed on the lights. Lights already fitted with motion sensors can be installed, but there are certain lights where motion sensors can be installed without them needing to be replaced. 

For museums with intermittent footfall throughout the day or across their building, installing movement sensors could significantly reduce the amount of electricity used in lighting empty rooms. 

Similarly, the installation of timers on lighting systems could be installed if there are areas which are used during certain hours of the day but not others, such as for displays or workshops. There are different types which can be utilised, such as automatic, programmable, wireless/smart, digital, exterior, light sensitive, miniature, staircase, twilight, and multi-channel timers.
