USE LOW-ENERGY
LIGHT BULBS
A simple environmental measure that will save money is to replace traditional, incandescent
bulbs with low-energy versions. They use 80 percent less electricity than incandescent bulbs
but produce as much light – a 20 watt energy-saving bulb is equivalent to a traditional 100 watt
bulb. They are also designed to last far longer – five or even 10 years – than traditional bulbs.
The incandescent bulb is a technology that is well over a century old by now, and is fast becoming obsolete.
Such bulbs are planned to be completely phased out of use in the UK by 2011.
Low energy light bulbs are now available for halogen fittings or dimmer switches, with a screw cap or bayonet
cap, and in soft tone lights for a warm glow rather than harsh fluorescent light: the last reasons for not using
the new bulbs have gone.
