Low running costs.

Range of colour temperatures 2700 – 6000 K.

Negatives:

Must have ballast/control gear in fitting.

Contain mercury and must be disposed of carefully.

Not dimmable except with electronic ballasts.

Compact fluorescent lighting (CFLs)

CFLs are highly energy efficient (usually class A) and are a good choice for areas requiring long periods of lighting, for example, living rooms, stores and toilets; however, it is clear that LED alternatives are now offering even greater advantages.

Both CFLs (and dedicated fittings for CFLs) are available in a wide range of sizes, shapes and colours. Some CFLs are suitable for dimming but require compatible control gear and dimmers.

Take care not to select CFLs that are overly large in size or unsuitable for the shade, enclosure or location in which they will be installed.

Positives:

Normally energy efficiency class A.
