Compact fluorescent bulbs

Energy efficient lamps are often equated with compact fluorescent lamps (CFLs). However, these are only one type of several existing low-energy light bulbs. CFLs are already widely used thanks to their very high level of efficiency.


Compact fluorescent lamps were first commercialised in the 1980's and are known for their long life and high efficiency. A compact fluorescent lamp uses between 65 and 80% less energy for the same light output than conventional incandescent light bulbs.

Compact fluorescent lamps sometimes come with an external envelope which hides the gas-filled tubes and makes them look even more similar to incandescent light bulbs. CFLs can last between 6,000 and 15,000 hours, depending on type and use. The lifetime for incandescent light bulbs is only about 1,000 hours. CFLs are known to be a “money saver” because of their high efficiency and lifetime.

However, because of their special features, they need to be carefully selected for the proper application. You will find here guidance on how to choose these lamps, in the form of a wizard and through an explanation of the information on the packaging.

When the compact fluorescent lamp ceases to function or if you break it accidentally, please observe the following advice.
