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.
Some more expensive models have a TRIAC dimmer circuit built into the stem. Early lamps with 300W bulbs tended to fail quickly. Early lamps with 300W bulbs tended to fail quickly. Retrofitting the lamp with a 100W bulb resulted in a substantial improvement in bulb life with minimal loss in brightness.
The square-wave nature of the power flow allows lamp life to be extended by as much as 20%. Most modern ballasts are now also equipped with a dimmer, which uses pulse-width modulation to dim the lamp up to 50%, or as much as one stop of light. Unlike a tungsten-based light, which has a negative color temperature shift with a drop in power, the ...
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.
