The use of automatic light dimming is an aspect of smart lighting that serves to reduce energy consumption. [13] Manual light dimming also has the same effect of reducing energy use. Use of sensors
Dimming fluorescent ballasts and dimming LED drivers often use 0–10 V control signals to control dimming functions. In many cases, the dimming range of the power supply or ballast is limited. If the light output can only be dimmed from 100% down to 10%, there must be a switch or relay available to kill power to the system and turn the light ...
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.
The term brownout comes from the dimming of incandescent lighting when voltage reduces. In some countries, the term brownout refers not to a drop in voltage but to an intentional or unintentional power outage (or blackout). [4] [5] [6]
Dimmable integrated helical CFL that dims 2–100%, comparable to standard light bulb dimming properties. Only some CFLs are labeled for dimming control. Using a dimmer with a standard CFL is ineffective and can shorten bulb life and void the warranty. [56] [57] Dimmable CFLs are available.
The toggle light switch was invented in 1916 by William J. Newton. [2] As a component of an electrical wiring or home wiring system, the installation of light switches is regulated by some authority concerned with safety and standards. In different countries the standard dimensions of the wall mounting hardware (boxes, plates, etc.) may differ.

Full-voltage vs. parking light headlamp on European-market Volkswagen, 2007. Depending on prevailing regulations and equipment, vehicles may implement the daytime-running light function by functionally turning on specific lamps, by operating low-beam headlamps or fog lamps at full or reduced intensity, by operating high-beam headlamps at reduced intensity, or by steady-burning operation of the ...
