Not only do modern light dimmers save you energy, but they also extend the life of your light bulbs! Dimmers use a “Triac Switch” to rapidly turn a light circuit on and off to reduce the energy flowing to a light bulb. This switch will cut the energy running to the fixture up to 120 times in one second.

Will dimmer switches save electricity?

Light dimmers save energy by reducing the flow of electricity to the bulb and allowing lights to operate with lower power outputs. Since lights under less stress shine longer, dimmers are known to extend the life span of your bulbs, too.

What we see is a constant light output. And dimmers do save. Dimming your lights an average of 50 percent can cut your electric use a whopping 40 percent over time and make your bulbs last 20 times longer!

Do dimmer switches use more or less electricity?

In fact, modern dimmer switches work by using circuitry that rapidly turns the electricity to the lights completely on or off, with the switching rate determining the brightness. As such, dimmer switches really do save energy.

1 Answer. Yes, dimmers reduce energy consumption of dimmable LEDs. Unlike incandescent bulbs, the electricity used is fairly linear with the light output; at 50% brightness it should use roughly 50% of the power. Generally speaking, dimming will allow the bulbs to run cooler and extend their life spans.

Are dimmer switches worth it?

When you use dimmers, it can also add longevity to your bulbs by reducing the amount of time the bulbs are at the highest point of energy exertion. … Even if you only dim the lights by 25 percent, you can see a significant amount of savings on your energy costs and help your light bulb last up to four times longer.

Are dimmer switches bad for your health?

Certain light bulbs and dimmer switches can contribute to electro-pollution, or potentially toxic electrical frequencies. … The dirty electricity then radiates into your home environment, potentially contributing to physical symptoms ranging from headaches to heart arrhythmia to an increased risk of chronic illnesses.

Why do dimmer switches buzz?

Dimmer switches work by chopping up the AC current flowing between the switch and the light. … The interrupted current can produce a vibration in the electromagnetic field within the light bulb filament or within the switch itself, which can cause a humming or buzzing noise.

What happens if you put a non dimmable LED bulb in a dimmer?

So what happens if you use non-dimmable LEDs on a dimmer? Well, at best the bulb just won’t dim properly. … But non-dimmable LEDs are only designed to be either fully powered ON or OFF, which means the circuitry inside won’t be able to handle low or pulsing current levels and will eventually become damaged.

Are dimmable lights more expensive?

LED dimmer switches are quite a bit more expensive than a traditional light switch but with good reason. … A better quality dimmer switch will last you longer and cause fewer potential problems to your lighting setup, so spend as much as you’re comfortable doing.

Do dimmers reduce voltage?

Does a dimmer switch reduce voltage? It works by changing the voltage waveform applied to the lamp, it is possible to lower the intensity of the light output.

Does dimming lights save energy Reddit?

In terms of saving energy, dimmers are still a success. One complication to these explanations is that the resistance of a filament lamp increases as it cools, ie. when it is dimmed, meaning efficiency doesn’t take quite as big a hit as you’ve calculated.

Do dimmers waste energy?

It really adds another dimension to your home’s lighting. So don’t be afraid to get dimmers for your home. They won’t be wasting you energy ” in fact they should save you a little and prolong the life of your bulbs.

Do LEDs last longer when dimmed?

Since dimming, either by reducing current or by pulse width modulation, results in lower overall junction temperatures, it will have no negative impact on LED life; it might even extend life.

Do smart bulbs save energy?

Let’s clarify: Because smart bulbs are LEDs, they are highly efficient and use much less energy than incandescent bulbs. … They do save considerable energy and ” thus ” money! However, when you compare smart bulbs to regular LEDs, the cost outweighs the money savings you get from switching to LEDs.

Are dimmer switches a fire hazard?

A dimmer can only be a fire hazard if you fail to read and follow the enclosed installation instructions. I have installed dimmer switches for years, and not one has ever caused an electrical fire. The reasons dimmer switches get hot is fairly simple. Some dimmers get hotter than others because of their design.

Do dimmable LED lights flicker?

The main cause of flickering with dimmable LED light can usually be traced back to the dimmer switch. … That’s why it’s important that you get a compatible LED dimmer switch to avoid any potential flickering. The quality of the dimmer switch you install will also have a bearing on the performance of your lights.

Why do LEDS flicker when dimmed?

LED bulb flickering can be traced in almost every instance to a non-compatible dimmer switch in the lighting circuit. … LED bulbs don’t have glowing filaments. When the dimmer switch goes off and on many times per second, the LED bulb becomes a flickering strobe light.

Can too much electricity make you sick?

Since then, many people have said they have EHS, especially as electronics have become more popular. Despite these reports, EHS is not a recognized illness in the medical field. Studies have failed to find a strong clinical relationship between EMFs and the reported symptoms.

Are dimmer switches bad for light bulbs?

Frequent and repeated adjustments on the dimmer switch can wear down the bulb’s internal components that can lead it to stop working. The upside is less power recessing the bulb, reducing the brightness, and dimming the light more efficiently. Some bulbs thrive with dimmers while other bulb types don’t do so well.

Are Edison style light bulbs dimmable?

Replica Edison incandescent bulbs are dimmable with fixtures with a dimmer switch and are less likely to have compatibility issues than an LED bulb. That said, if you choose an LED Edison bulb, you may experience flickering even if the product is marketed as dimmable.

Why do I hear a vibrating sound in my house?

Some possible reasons why you might hear a vibrating or humming noise coming from a wall include: The connections inside an electrical outlet or switch could be going bad. The screws that fasten the wires to the outlet or switch might be loose. … A half-opened air vent on the wall may be buzzing due to high air pressure.

Do LED lights make a buzzing noise?

LEDs lack a filament or firing arc so there are no “moving parts” to cause humming. Unfortunately, LEDs still suffer from electromagnetic (EM) hum caused by incorrect dimming or EM interference by other devices. … But, if your lights hum when dimmed or installed into sockets connected to a dimmer, it’s simple to fix.

Do all dimmers buzz?

Here’s a fun fact: Almost all dimmers hum. When the room is absolutely silent, and the bulbs have been dimmed down to less than 50%, you put your ears close to the dimmer switch. Chances are, you will hear some buzzing or, at the very least, humming.

Can you use a dimmer switch on any light?

Most light fixtures will work with standard dimmer switches, including those with halogen and incandescent lamps. … If you install line-voltage track and rail lights with incandescent bulbs, you can use dimmer switches to control their brightness. Just be sure to use a line-voltage dimmer as well.

Are LED lights bad for your eyes?

The “blue light” in LED lighting can cause damage to the eye’s retina and also disturb natural sleep rhythms, according to a new report. … “Exposure to an intense and powerful (LED) light is ‘photo-toxic’ and can lead to irreversible loss of retinal cells and diminished sharpness of vision,” it said.
