LEDs may be costlier to begin with, but by doing the energy switch, you’ll be saving up to 90% in the long run, helping you protect your bank balance and the planet! With an average lifespan of 40,000 hours, LEDs stomp all over halogen/incandescent with an average lifespan of 1,500 hours. A significant difference! Like we said, LEDs may be costlier but with a £2.50 annual energy cost per bulb as opposed to £20.00, it’s clearly the smarter, more efficient choice.
