Building and Stage Lighting
In stage lighting, sealed beam lamps are often used. A common size, also used in rock concerts, as well as outdoor architectural lighting, is the parabolic aluminumized reflector 64 (PAR64). PAR64 sealed beam lamps are typically available with 250, 500 or 1000 watt power ratings.The fixtures that such sealed beam lights go into are called "PAR cans". Beam spreads are designated as FL (flood), SP (spot), NSP (narrow spot), and VNSP (very narrow spot), as stamped on the back of the lamp's reflector.

Famous quotes containing the words building, stage and/or lighting:
“A building is akin to dogma; it is insolent, like dogma. Whether or no it is permanent, it claims permanence, like a dogma. People ask why we have no typical architecture of the modern world, like impressionism in painting. Surely it is obviously because we have not enough dogmas; we cannot bear to see anything in the sky that is solid and enduring, anything in the sky that does not change like the clouds of the sky.”
—Gilbert Keith Chesterton (1874–1936)
“She does not realize that the only difference between us is that she is on one stage and I on another. I feel that I am acting just as much as she is.”
—William Howard Taft (1857–1930)
“Popular art is normally decried as vulgar by the cultivated people of its time; then it loses favor with its original audience as a new generation grows up; then it begins to merge into the softer lighting of “quaint,” and cultivated people become interested in it, and finally it begins to take on the archaic dignity of the primitive.”
—Northrop Frye (b. 1912)
