A major benefit of lighting control systems is reduced energy consumption. Longer lamp life is also gained when dimming and switching off lights when not in use. Wireless lighting control systems provide additional benefits including reduced installation costs and increased flexibility over where switches and sensors may be placed. [3]
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.
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 ...
Everyone wants to turn their house into their dream home, or at least make small updates here and there, but that's often easier said than done. Whether you're upgrading your space or gearing up to...
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.
Joel Solon Spira (March 1, 1927 – April 8, 2015) was an American inventor, entrepreneur, and business magnate.. He invented a version of the light-dimmer switch for use in homes around the United States and led his Lutron Electronics Company into the production of lighting controllers.
In addition to the light plot there are a number of other important pieces of paperwork (i.e. dimmer hookup, instrument schedule, and magic sheet) in a complete lighting design. As each part of the lighting design is relevant only to a specific group of technicians, the entire design is generally provided only to the director and master ...
General Motors is adding over 132,000 heavy-duty pickups in the U.S. to a previous recall for tailgate release switches that can short circuit and open the gates while the trucks are in park. The ...
