Compact fluorescent lamps (CFLs) are long life, energy saving light bulbs which are much more efficient than both incandescent and halogen bulbs. However, they require fittings with appropriate lamp holders, and an appropriate ballast (a device used to provide the starting voltage and regulate the current to the pins on the lamp). 4 pin lamps can be dimmed when operated on an electronic dimmable ballast. If you want to use a CFL with a dimmer switch then look out for dimmer compatible bulbs which should be clearly marked, the bulbs in the Osram DINT LL range are a good example of a dimmable CFL.
Compact fluorescent bulbs use less energy than standard incandescent lamps, turning up to 25% of the electricity they use in to light (20% more than incandescent bulbs) as well as lasting up to 20 times longer. A 20w CFL produces the same amount of light as a 75w incandescent bulb, so it’s easy to see how you can save energy by switching to this type of bulb.
Although older style CFLs can take a little while to warm up, around 30 seconds, newer style lamps are now being designed which light almost instantly.
