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.

Kazan (; Tatar: Казан; Russian: Каза́нь, IPA: [kɐˈzanʲ]), is the capital and largest city of the Republic of Tatarstan in Russia. The city lies at the confluence of the Volga and the Kazanka rivers, covering an area of 425.3 square kilometres (164.2 square miles), with a population of over 1.2 million residents, up to roughly 1.6 million residents in the urban agglomeration. Kazan is the fifth-largest city in Russia, and the most populous city on the Volga, as well as the Volga Federal District.
Ancient Kazan was founded in the late 13th century by the Golden Horde. In 1438, Kazan became the capital of the Khanate of Kazan. In 1552, Kazan was captured by Ivan the Terrible and became a part of Russia. The city was seized and largely destroyed during Pugachev's Rebellion of 1773–75, but was later rebuilt during the reign of Catherine the Great.
