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.

Angol is a commune and capital city of the Malleco Province in the Araucanía Region of southern Chile. It is located at the foot of the Nahuelbuta Range and next to the Vergara River, that permitted communications by small boats to the Bío-Bío River and Concepción. This strategic position explains the successive foundations of this city during the Arauco War. It was first founded in 1553 as a "conquistador" fort of Confines, the fort was later destroyed and rebuilt several times and it was not until the Pacification of Araucania in the late 19th century that it was rebuilt with the name of Angol.
