2. 3-way lamp - Wikipedia

   en.wikipedia.org/wiki/3-way_lamp

   A 3-way lamp, also known as a tri-light, is a lamp that uses a 3-way light bulb to produce three levels of light in a low-medium-high configuration. A 3-way lamp requires a 3-way bulb and socket, and a 3-way switch. In 3-way incandescent light bulbs, each of the filaments operates at full voltage. Lamp bulbs with dual carbon filaments were ...

3. Stroboscopic effect - Wikipedia

   en.wikipedia.org/wiki/Stroboscopic_effect

   The temporal light modulation may come from fluctuations of the light source itself or may be due to the application of certain dimming or light level regulation technologies. Another cause of light modulations may be lamps with unfiltered pulse-width modulation type external dimmers. Whether this is so may be tested with any quickly-rotating ...

4. Touch-sensitive lamp - Wikipedia

   en.wikipedia.org/wiki/Touch-sensitive_lamp

   Video demonstrating the operation of a touch-sensitive lamp. A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may ...

5. 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.

   en.wikipedia.org/wiki/Intelligent_lighting

   In 1969, Jules Fisher, from Casa Mañana area theatre in Texas saw the invention and use of 12 PAR 64 lanterns with 120 W, 12 V lamps fitted, 360 degrees of pan and 270 degrees of tilt, a standard that lasted until the 1990s. This lamp was also known as the 'Mac-Spot' [1] In Bristol in 1968, progress was also being made, mainly for use in live ...

8. Pearson–Anson effect - Wikipedia

   en.wikipedia.org/wiki/Pearson–Anson_effect

   The bulb's "turn on" voltage V b is higher than its "turn off" voltage V e. This property, called hysteresis, allows the bulb to function as an oscillator. Hysteresis is due to the bulb's negative resistance, the fall in voltage with increasing current after breakdown, [7] [14] which is a property of all gas-discharge lamps.

9. Bi-pin lamp base - Wikipedia

   en.wikipedia.org/wiki/Bi-pin_lamp_base

   The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...
