Lumen (unit)
The lumen (symbol: lm) is the unit of luminous flux, a measure of the total quantity of visible light emitted by a source per unit of time, in the International System of Units (SI). Luminous flux differs from power (radiant flux) in that radiant flux includes all electromagnetic waves emitted, while luminous flux is weighted according to a model (a "luminosity function") of the human eye's sensitivity to various wavelengths. One lux is one lumen per square metre. The lumen is defined in relation to the candela as : 1 lm = 1 cd· sr. A full sphere has a solid angle of 4π steradians, so a light source that uniformly radiates one candela in all directions has a total luminous flux of :. Explanation If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cd·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lumen (band)
Lumen is a Russian rock band from Ufa. It has released seven studio albums to date. The band considers February 12, 1998 as its birthday because on that date it performed as "Lumen" for the first time. The band's earlier works have an alternative rock sound with a strong influence of punk. However, they took a heavier approach on later releases. The lyrics are usually written by singer and frontman Rustem "Tem" Bulatov. The band's songs are inspired by diverse controversial events and issues which take place inside and outside Russia, as well as personal struggles. Biography 1996–2000 Rustem Bulatov (vocals), Igor Mamaev (guitar) and Denis Shakhanov (drums) had been jamming together with different bass players.

Lumen (website)
Lumen, formerly Chilling Effects, is an American collaborative archive created by Wendy Seltzer and founded along with several law school clinics and the Electronic Frontier Foundation to protect lawful online activity from legal threats. Lumen is a "project" of the Berkman Klein Center. Its website, ''Chilling Effects Clearinghouse'', allows recipients of cease-and-desist notices to submit them to the site and receive information about their legal rights and responsibilities. Founded in 2001 in San Francisco, California, it later moved its operations to Massachusetts. Inception The archive was founded in 2001 by Internet activists who were concerned that the unregulated private practice of sending cease-and-desist letters seemed to be increasing and was having an unstudied, but potentially significant, "chilling effect" on free speech. The archive got a boost when Google began submitting its notices to the site in 2002. Google began to do so in response to the publicity gene ...

Lumen Martin Winter
