What is it?
Low energy lighting is an energy efficient alternative to traditional incandescent, tungsten, or filament light bulbs. There are a number of different kinds of low energy light bulbs available, including compact fluorescent lights (CFLs) and LEDs.
How does it work?
These products require less electricity to run than traditional light bulbs. Low energy light bulbs also last longer than conventional light bulbs and don't need to be replaced as often.
This is one of the simplest methods of increasing energy efficiency, reducing electricity bills and lowering CO2 emissions.
According to uSwitch, installing five low energy light bulbs could generate annual savings of up to £32.
