\cf0 Have you gone to touch your light dimmer and felt that it is very warm even hot?
The reason dimmer switches get hot is fairly simple. Some dimmers get hotter than others because of their design. Old dimmer switches typically were rheostats that varied the amount of voltage going to the light bulbs. As the rheostat was turn down to lower the voltage, the electricity was changed into heat. These old dimmers wasted lots of energy.
Modern dimmer switches use slick internal electronics to dim the lights. These components can turn the light on and off 120 times per second. This is too fast for you to see. By altering the amount of time the switch is off rather than on, you see a lower amount of light out of the bulb. This method of dimming is highly efficient. Well over 90 percent of the electricity that does flow into the switch gets used in the light bulb. The heat that you feel in modern dimmers simply is a result of the ordinary friction of the electricity flowing through the device.
Modern electronic dimmers have a heat sink or metal plate that directs this heat towards the room. This is why you feel the heat on the cover plate. This is done intentionally. Over time, excessive heat could damage the house wiring or the internal components of the dimmer switch.
You don’t need any special wiring to connect a typical residential dimmer switch. If you have a standard toggle switch in place now that operates the light, a dimmer can replace this switch. You can even get three way dimmer switches that allow you to operate a light from two different switches.
Be aware that dimmer switches can only handle a specific amount of light load. You can typically purchase dimmers that are rated for 600 or up to 1,000 watts of lighting. Light bulbs are usually clearly marked as to their wattage. Determine the total wattage of the bulbs that are being controlled by any one dimmer.
