2. 50 Times Cheap Fixes Had A Major Impact On Home Life - AOL

   www.aol.com/55-people-share-relatively-cheap...

   The only lighting my house had was from ceiling fans so most of the rooms were way too dark. Adding 4 recessed lights on a dimmer switch is under $200/room and is such a quality of life ...

3. Dimmer - Wikipedia

   en.wikipedia.org/wiki/Dimmer

   When the dimmer is at 50% power, the switches are switching their highest voltage (>325 V in Europe) and the sudden surge of power causes the coils on the inductor to move, creating a buzzing sound associated with some types of dimmer; this same effect can be heard in the filaments of the incandescent lamps as "singing". The suppression ...

4. Compact fluorescent lamp - Wikipedia

   en.wikipedia.org/wiki/Compact_fluorescent_lamp

   The dimmer switch used in conjunction with a dimmable CFL must be matched to its power consumption range; [58] many dimmers installed for use with incandescent bulbs do not function acceptably below 40 W, whereas CFL applications commonly draw power in the range 7–20 W. Dimmable CFLs have been marketed before suitable dimmers are available.

5. 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]

6. 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.

7. Lighting control console - Wikipedia

   en.wikipedia.org/wiki/Lighting_control_console

   Lighting consoles communicate with the dimmers and other devices in the lighting system via an electronic control protocol. The most common protocol used in the entertainment industry today is DMX512 , although other protocols (e.g. 0-10 V analog lighting control ) may still be found in use, and newer protocols such as ACN and DMX-512-A are ...
