In 1902, Dakar replaced Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. In 1960, it became the capital of the Independent Republic of Senegal.

The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted according to the luminosity function, a standardized model of human visual brightness perception.

In English, "lux" is used as both the singular and plural form.The word is derived from the Latin word for "light", lux.
