Lighting and Display Gas-filled Tubes
Fluorescent lighting, CFL lamps, mercury and sodium discharge lamps and HID lamps are all gas-filled tubes used for lighting.
Neon lamps and neon signage (most of which is not neon based these days) are also low-pressure gas-filled tubes.
Specialized historic low-pressure gas-filled tube devices include the Nixie tube (used to display numerals) and the Decatron (used to count or divide pulses, with display as a secondary function).
Xenon flash lamps are gas-filled tubes used in cameras and strobe lights to produce bright flashes of light.
The recently developed sulfur lamps are also gas-filled tubes when hot.

Famous quotes containing the words lighting and/or display:

—William James (1842–1910)
“I mistrust the satisfaction which makes a display of the possession of Infinity; that is called fatuity in philosophic terms.”
—Edgar Quinet (1803–1875)
