Do light bulbs use less energy when dimmed.

Use slightly less energy than cfls. Halogen bulbs use about 20 percent less energy when dimmed. However the more you dim these incandescent lights the less efficient they will be. But before investing in a dimmer switch it s critical to ensure that your cfl bulbs are compatible.

The bulb is therefore on on average for less time than it would be if directly connected. These led a19 bulbs are designed as a direct replacement for your old incandescent light bulbs while consuming less power. Typically use about 25 80 less energy than traditional incandescents saving you money. Dimmer switches turn the current to the bulb off until a preset but variable stage in each cycle.

For example a 60w bulb dimmed to the brightness of a 40w bulb will use more energy than a 40w bulb on maximum. Use about 80 percent less electricity while providing the same brightness of the incandescents they replace. Today s energy efficient bulbs are available in the wide range of colors and light levels you ve come to expect. This dimmable a19 led bulb is a top choice.

The thing is that in many places where we use the lights they might be dimmed 50 of the time. The light will also tend to be warmer in colour. However dimming incandescent is actually less efficient than using a lower wattage of bulb. Therefore if you care about electric efficiency you should adjust brightness by number of light bulbs that are switched on or by changing to bulbs with lower wattage.

These led light bulbs use up to 90 percent less energy than their incandescent equivalents while producing the same lumen output. Nowadays dimmer switches for led lights work by actually reducing energy used and only uses enough energy that it needs to power the light bulb at the setting of your dimmer. Instead of reducing the amount of energy being used they simply converted the energy not being used into heat instead of full illumination capability of the light bulb. With led lights the effect of dimming compared to power use is fairly linear.
