Lux

The lux (symbol: lx) is the SI unit of illuminance and luminous emittance, 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 watts 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 in both singular and plural.

Explanation

Illuminance

Illuminance is a measure of how much luminous flux is spread over a given area. One can think of luminous flux (measured in lumens) as a measure of the total "amount" of visible light present, and the illuminance as a measure of the intensity of illumination on a surface. A given amount of light will illuminate a surface more dimly if it is spread over a larger area, so illuminance (lux) is inversely proportional to area when the luminous flux (lumens) is held constant.

Lux (soap)

LUX is a global brand developed by Unilever. The range of products includes beauty soaps, shower gels, bath additives, hair shampoos and conditioners. Lux started as “Sunlight Flakes” laundry soap in 1899.

In 1925, it became the first mass-market toilet soap in the world. It is noted as a brand that pioneered female celebrity endorsements.

As of 2009, Lux revenue was estimated at €1 billion, with market shares spread out to more than 100 countries around the globe.

Today, Lux is the market leader in countries like India, Pakistan, Brazil, Thailand and South Africa

Developed by Unilever, Lux (soap) is now headquartered in Singapore.

History

Origins and history

The brand was founded by the Lever Brothers (today known as Unilever) in 1899. The name changed from “Sunlight Flakes” to “Lux” in 1900, a Latin word for “light” and suggestive of “luxury.”

Lux toilet soap was launched in the United States in 1925 and in the United Kingdom in 1928. Subsequently, Lux soap has been marketed in several forms, including handwash, shower gel and cream bath soap.

Jazz

Jazz is a music genre that originated from African American communities of New Orleans in the United States during the late 19th and early 20th centuries. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz spans a period of over a hundred years, encompassing a very wide range of music, making it difficult to define. Jazz makes heavy use of improvisation, polyrhythms, syncopation and the swing note, as well as aspects of European harmony, American popular music, the brass band tradition, and African musical elements such as blue notes and African-American styles such as ragtime. Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience to the music as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".

Jazz (Kanso series) is a series of 20 paintings made by Nabil Kanso in 1978-79. The subjects of the works are based on the jazz music and the entertainments night life in New York and New Orleans. The paintings are done in oil and acrylic on canvas measuring 224 X 182 cm (88 X 72 inches) each. Their compositions reflect predominant red tonality built with broad brushstrokes. Works from the series were exhibited in Atlanta in 1985.
