   Talaria was the brand name of a large-venue video projector from General Electric introduced in 1983. [1]Early model GE Talaria light valve video projector. Light from a Xenon arc lamp was modulated by a light valve consisting of a rotating glass disc that was continuously re-coated with a viscous oil.

3. Mogul lamp - Wikipedia

   en.wikipedia.org/wiki/Mogul_lamp

   Mogul lamps are also the subject of a mathematics problem concerning the number of possible combinations of power that can be obtained. As it turns out, the name "Six Way Lamp" is somewhat deceiving since there are in fact 16 possible combinations (without the night-light), including combinations with all lamps of either switch off.

4. Fluorescent-lamp formats - Wikipedia

   en.wikipedia.org/wiki/Fluorescent-lamp_formats

   These lamps are similar to the regular black light lamps, except they use wood's glass as a filter to reduce the amount of visible light emitted. These lamps are used for fluorescence effects where less visible light is ideal. 09 N/A Sun-tanning lamps: These lamps produce wide or narrow band UV-B radiation 10 BL Black-Light lamps: Black light ...

5. Balanced-arm lamp - Wikipedia

   en.wikipedia.org/wiki/Balanced-arm_lamp

   A balanced-arm lamp has a base, a stand or body, (in most cases) two connected arms (in many cases fitted with springs), and a lamp-head. The lamp can be moved into almost any position, and the balancing device will maintain the position until moved again. The same overall mechanism can be employed in other devices with similar requirements ...

6. Xenon arc lamp - Wikipedia

   en.wikipedia.org/wiki/Xenon_arc_lamp

   A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure. It produces a bright white light to simulate sunlight , with applications in movie projectors in theaters , in searchlights , and for specialized uses in industry and research.

7. High-intensity discharge lamp - Wikipedia

   en.wikipedia.org/wiki/High-intensity_discharge_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.
