How to calculate electricity savings?
You will need to look over your electricity bills and see what the utility charges per kWh. Multiply the rate per kWh by the amount of electricity saved, and this will give you the value of the savings. Continuing with the example above, let us say that your electric rate is 10 cents per kWh. The value of the energy savings would then be 0.4 cents ($ 0.004). The value of the savings will increase the higher the watt rating of the bulb, the greater the number of bulbs controlled by a single switch, and the higher the rate per kWh.

Do light bulbs need to be on before turning off?
Lighting manufacturers should be able to supply information on the duty cycle of their products. In general, the more energy-efficient a lightbulb is, the longer you can leave it on before it is cost effective to turn it off.
Do LEDs have a lifetime?
While lifetime is reduced for fluorescent lamps the more often they are switched on and off, there is no negative effect on LED lifetime. This characteristic gives LEDs several distinct advantages when it comes to operations. For example, LEDs have an advantage when used in conjunction with occupancy sensors or daylight sensors that rely on on-off operation. Also, in contrast to traditional technologies, LEDs turn on at full brightness almost instantly, with no delay. LEDs are also largely unaffected by vibration because they do not have filaments or glass enclosures.

Actually, the dimmer switch was invented way back in 1959 by Joel Spira, who patented his invention and then founded Lutron Electronics in 1961. The company eventually became the leader in the lighting control industry.
How many watts does a dimmer use?
Dimmers for home lighting fixtures come in several wattages, ranging between 150 watts to 1000 watts. When dimming LED lights, calculate the dimmer load by dividing the dimmer’s maximum load, which you can find in the package, by 10. That means a 500 watts dimmer can accommodate 50 watts of LED bulbs or 10 5-watt bulbs.
How do old dimmer switches work?
Old dimmer switches work by diverting energy from a light bulb into a resistor to raise or lower the brightness of the light. The resistor, called a rheostat, controls the amount of power that goes into the light by turning that energy into heat. As such, old dimmers don’t reduce energy usage but instead are only effective for mood lighting.
Why do LED lights buzz when dimmed?
However, if you hear buzzing when you dim your bulbs, the problem may have to do with compatibility issues between the LED lights and your dimmer. You see, not all dimmer switches work with LED lights. Those designed for incandescents, for example, can lead to that humming sound you hear.
