What are the different types of light bulbs?

Incandescent lamps are standard domestic light bulbs including GLS, candle, golfball and many others.

Halogen lamps are high intensity, optimised lamps giving better efficiency than standard light bulbs.

Energy saving lamps are direct replacements for standard light bulbs that last up to 12 times as long and save on energy consumption. Switching to these lamps can save the average household £7 per year per lamp.
