  • Ford Focus (first generation)


    The Ford Focus (first generation) is a compact car that was manufactured by Ford in Europe from 1998-2004 and by Ford in North America from 1999-2007. Ford began sales of the Focus to Europe in July 1998 and in North America during 1999 for the 2000 model year. Manufacturing in Argentina continued until 2008, and it was still on sale in Brazil until 2009. In Europe and South Africa, the Focus replaced the various Ford Escort models sold in those markets. In Asia and Australasia, it replaced the Ford Laser.

  • High-intensity discharge lamp


    15 kW xenon short-arc lamp used in IMAX projectorsHigh-intensity discharge lamps (HID lamps) are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. This tube is filled with noble gas and often also contains suitable metal or metal salts. The noble gas enables the arc's initial strike. Once the arc is started, it heats and evaporates the metallic admixture. Its presence in the arc plasma greatly increases the intensity of visible light produced by the arc for a given power input, as the metals have many emission spectral lines in the visible part of the spectrum. High-intensity discharge lamps are a type of arc lamp. Brand new high-intensity discharge lamps make more visible light per unit of electric power consumed than fluorescent and incandescent lamps, since a greater proportion of their radiation is visible light in contrast to infrared. However, the lumen output of HID lighting can deteriorate by up to 70% over 10,000 burning hours.
