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.

Esquel is a town in the northwest of Chubut Province in Argentine Patagonia. It is located in Futaleufú Department, of which it is the government seat. The town's name derives from one of two Tehuelche words. One meaning "marsh" and the other meaning "land of burrs", which refers to the many thorny plants including the pimpinella and other herbaceous plants whose fruits, when ripe turn into prickly burrs that stick to the animals' skins and wool or people's clothes as a way of propagation.
