2. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   A common dual dimmer module used in stage lighting A dimmer. A dimmer is a device connected to a light fixture and used to lower the brightness of the light.By changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.

3. Light switch - Wikipedia

   en.wikipedia.org/wiki/Light_switch

   Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]

4. Light fixture - Wikipedia

   en.wikipedia.org/wiki/Light_fixture

   Permanent light fixtures, such as dining room chandeliers, may have no switch on the fixture itself, but rely on a wall switch. Fixtures require an electrical connection to a power source, typically AC mains power, but some run on battery power for camping or emergency lights. Permanent lighting fixtures are directly wired.

5. Fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Fluorescent_lamp

   Fluorescent light fixtures cannot be connected to dimmer switches intended for incandescent lamps. Two effects are responsible for this: the waveform of the voltage emitted by a standard phase-control dimmer interacts badly with many ballasts, and it becomes difficult to sustain an arc in the fluorescent tube at low power levels.

6. Lighting control console - Wikipedia

   en.wikipedia.org/wiki/Lighting_control_console

   These include an array of buttons allowing the operator to select the fixture or fixtures they want to control, and a joystick, or a number of wheels or rotary encoders to control fixture attributes such as the orientation (pan and tilt), focus, colour, gobos etc. found in this type of light. Unlike a fader that shows its value based on the ...

7. Electrical ballast - Wikipedia

   en.wikipedia.org/wiki/Electrical_ballast

   A quadrac type light dimmer can be used with a dimming ballast, which maintains the heating current while allowing lamp current to be controlled. A resistor of about 10 kΩ is required to be connected in parallel with the fluorescent tube to allow reliable firing of the quadrac at low light levels.
