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.

Bairnsdale () is a city in East Gippsland, Victoria, Australia in a region traditionally owned by the Tatungalung clan of the Gunaikurnai people.The estimated population of Bairnsdale urban area was 15,411 at June 2018. The city is a major regional centre of eastern Victoria along with Traralgon and Sale and the commercial centre for the East Gippsland region and the seat of local government for the Shire of East Gippsland. Bairnsdale was first proclaimed a shire on 16 July 1868 and it was proclaimed as a city on 14 July 1990.The origin of the city's name is uncertain. It was possibly Bernisdale, with "Bernis-dale" originating from "Bjorn's dale, or glen", which indicates the Viking origins of the Skye Village. Legend has it that Macleod was so impressed by the large number of children on the run, the children of his stockmen, that he called it Bairns-dale, or "valley of the children".In 1876 the Bairnsdale Shire, which went on to become one of the largest in Victoria in the 1880s, was led out of administrative chaos by former shire auditor and shipping agent Herman Bredt.
