One of the best ways to cut back on lighting-related costs is to use only the light you need and no more. This means you save power, and you may even experience aesthetic improvements as an added benefit!
Lighting engineer, academic and author Robert Bean says that while lighting improves our ability to see, there comes a point when there’s more light than we actually need.
“It has been found that although increasing lighting levels improves visual performance, after a certain level of performance has been reached, further increases in the lighting level bring relatively little improvement. In this respect sight obeys similar laws to the other senses such as hearing.” — Bean, Robert; Lighting Interior and Exterior (2014)
In other words, think about how you light your home in terms of what you need and want, rather than just flicking the switch and flooding the room.
Here’s how to achieve more efficient lighting in your home:
- Think about taking the task lighting approach
- Light a room according to its function
- Consider our four off-the-wall measures to brighten a room and reduce energy use
- Consider using modern Light-Emitting Diode (LED) lighting to replace older — and more inefficient — bulbs.
