Their curly appearance marked them out from the rest, although round and flame shapes are available nowadays. CFLs use 70-80% less electricity than traditional light bulbs and last about 10 times longer. Not all CFLs are dimmable.

   Which light bulb is most energy efficient?

   • LEDs are the most energy-efficient light bulbs on the market, followed by CFLs and then incandescent light bulbs. That’s because LEDs convert more electricity into light than other bulbs and lose less energy as heat. For example, the 60-watt equivalent of a traditional light bulb is a 10-watt LED bulb.

   How much does a 100W light bulb cost per hour?

   • Taking the example above, that a 100W light bulb uses 0.1kW an hour, this means that ten 100W light bulbs on at the same time would require 1kW, which would cost 25p every hour. Swap that for ten 18W LED light bulbs and the cost is significantly less: 18W is 0.018kW x 10 = 0.18kW, so the cost every hour is just over 4p (4.5p to be precise).
