A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
Fluorescent tube lighting can be purchased at any do-it-yourself retail outlet such as Homebase. Alternatively you may purchase some online with a more varied size and colours from websites such as Amazon.
