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:
“What I like, or one of the things I like, about motoring is the sense it gives one of lighting accidentally, like a voyager who touches another planet with the tip of his toe, upon scenes which would have gone on, have always gone on, will go on, unrecorded, save for this chance glimpse. Then it seems to me I am allowed to see the heart of the world uncovered for a moment.”
—Virginia Woolf (1882–1941)
“In the early forties and fifties almost everybody “had about enough to live on,” and young ladies dressed well on a hundred dollars a year. The daughters of the richest man in Boston were dressed with scrupulous plainness, and the wife and mother owned one brocade, which did service for several years. Display was considered vulgar. Now, alas! only Queen Victoria dares to go shabby.”
—M. E. W. Sherwood (1826–1903)
