In incandescent light bulbs, electricity is converted to heat in the tungsten, which mean more heat is dissipated as compared to LED options.
Swop incandescent bulbs at home with LED ones – they’re also more energy-efficient and last longer as they require less electricity to produce the same light output.
“Look out for the energy label on the light bulb packaging. Bulbs with a three-tick rating are the best in terms of energy efficiency, and will save the most electricity,” advises lighting experts from Philips.
The Philips Classic LED range (pictured) looks the part, yet uses around 80 per cent less energy compared to traditional light bulbs.
