The urban area of the parish of St Helier makes up most of the largest town in Jersey, although some of the town area is situated in adjacent St Saviour, with suburbs sprawling into St Lawrence and St Clement.

The greater part of St Helier is rural. The parish covers a surface area of 4.1 square miles (10.6 km2), being 9% of the total land area of the island (this includes reclaimed land area of 494 acres (2.00 km2) or 200 ha). The parish arms are two crossed gold axes on a blue background, the blue symbolising the sea, and the axes symbolising the martyrdom of Helier at the hands of Saxon pirates in 555 AD.

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.
