Meaning and Definition

A type of electric light that produces visible light by causing a phosphor coating inside a glass tube to fluoresce when excited by ultraviolet light generated by an electric discharge in mercury vapour.

A common, energy-efficient lighting fixture, typically in the form of a long glass tube or compact spiral bulb, used widely in offices, schools, and commercial buildings. The term can also refer to the entire lighting unit, including the ballast and fixture.

Dialectal Variation

British vs American Usage

Differences

In British English, the long tubular version is commonly called a 'fluorescent tube' or 'strip light'. In American English, 'fluorescent light' or 'fluorescent bulb' is more common for all forms. The compact version is universally a 'compact fluorescent lamp' (CFL).

Connotations

Connotations are similar: associated with institutional, office, or industrial lighting, sometimes perceived as harsh or cold compared to warmer domestic lighting.

Frequency

The term is standard in both varieties. 'Strip light' is more frequent in UK everyday speech for the tubular type.

FAQ

Frequently Asked Questions

No. They are different technologies. An LED tube uses light-emitting diodes and does not contain mercury vapour or require a ballast in the same way. However, LED tubes are often designed to fit into old fluorescent lamp fixtures.

Flickering is often caused by a failing starter (in older models), a faulty ballast, or the lamp reaching the end of its lifespan. Cold temperatures can also cause a slow start and flicker.

No. Fluorescent lamps require a specific fixture with a ballast to regulate the electrical current. You cannot screw a tubular fluorescent lamp into a standard incandescent bulb socket.

In many regions, yes, due to energy efficiency regulations and the superior efficiency and longevity of LED lighting. The sale of certain types of fluorescent lamps is banned or being phased out in the EU, UK, and parts of the US.
