Do Light Dimmer Switches Save Energy?
What You Need to Know About the Relationship Between Light Dimmers and the Amount of Energy Used in Your Home
Since the early 1960s, dimmer switches have become a standard fixture in many residential dwellings. By regulating the amount of light that is produced by the lightbulb, they make it possible for you to alter the ambience of a room. The installation of a dimmer switch is an excellent approach to alter the visual attractiveness of a space. However, does turning down the lights genuinely result in a savings of energy?
Dimmers for the lights: do they save energy?
Over the course of the last few decades, the technology used in residential lighting has gotten more energy efficient. Dimmers for modern lights not only help you save money on your electricity bill, but they also make your light bulbs last longer.
Dimmers make use of something called a "Triac Switch" to rapidly turn a light circuit on and off in order to minimise the amount of energy that is being supplied to a light bulb. This switch can interrupt the flow of electricity to the fixture as many as one hundred and twenty times in a single second. The human eye will interpret this as a steady flow of light, but in reality, it is an extremely rapid flickering of light.
Dimmers are not compatible with all light bulbs.
Although more recent light bulbs such as halogen, compact fluorescent lamps (CFLs), and light emitting diodes (LEDs) are superior to conventional light bulbs in terms of energy efficiency and lifespan, older light fixtures may be incompatible with them.
If you have ever tried to replace an incandescent light bulb that is attached to a dimmer with a newer type of bulb, you will have a very clear example of this phenomenon. It's quite likely that it didn't work! When compared to the typical wattage consumption of an incandescent light bulb, the energy consumption of newer light bulbs such as LEDs is so much lower that an older dimmer switch could not even notice the difference.
Using Dimmers with Incandescent Light Bulbs You might think that using less light would result in less energy being consumed, but that's not necessarily the case.
It is important to note that this is not always the case with all dimmers. Older light dimmers, sometimes known as legacy dimmers, were designed to be used with conventional incandescent light bulbs. These dimmers are no longer manufactured. They functioned by reducing the amount of electricity that could flow into the lightbulb, which caused the lightbulb to emit less light. However, this did not necessarily result in any energy savings.
When the light is turned down, the current is decreased because the energy is converted into heat rather than light. This results in a reduction in the amount of light that is produced by the bulb; nevertheless, there is no change in the amount of electricity that is consumed.
Get rid of your old-fashioned incandescent light bulbs if you want to reduce your monthly power costs and your impact on the environment at the same time.
Combining a Halogen Light Bulb with a Dimmable Light Switch
The vast majority of dimmer switches are compatible with new halogen bulbs, but this compatibility comes at the expense of the bulb's overall lifespan. Dimmable halogen bulbs require more frequent replacement, but they save around 20 percent more power than standard bulbs.
Using a Dimmer Switch with Compact Fluorescent Light Bulbs
CFL lamps consume an even smaller amount of energy than halogen bulbs, but unfortunately, not all of them are compatible with dimmer switches. Because a regular compact fluorescent light (CFL) bulb cannot be used in a dimmable fixture, you will need to look for one that specifically states that it is suitable.
Combining Dimmer Switches with LED Light Bulbs
The most energy-efficient light bulbs for the home are light emitting diodes (LEDs), and purchasing a dimmer will help you save even more money on your electricity bill. However, similar to CFLs, the majority of LED bulbs are incompatible with regular dimmer switches. If you use a bulb that is not compatible with the fixture, you may experience buzzing, flickering, and even damage to the light.
