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.
Does dimming lights save energy LED?
Yes. The brighter an LED is, then the more energy it is using. Therefore a dimmed LED is using less energy than an identical LED running at full brightness.
How much electricity do dimmers save?
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 you waste more electricity by turning the lights on and off?
Despite myths you may have heard, turning your lights on and off doesn’t use more electricity than leaving your lights on. Turning off the lights when you aren’t in a room is one of the easiest ways to save energy.

Why are some LED lights not dimmable?
Damage or failure – LED driver, circuit or LED is damaged or fails. Load below minimum – The power load of the LED lamp is below the minimum required by the dimmer. Mixed models- Different models of LED will likely have different drivers – since drivers behave differently this could result in dimming issues.
Are dimmable lights better?
If you’re looking for a more energy-efficient option, dimmable LED lights are a great choice. LEDs use about 80% less energy than traditional incandescent bulbs, and they last up to 25 times longer. This means that you’ll save money on your energy bill in the long run by making the switch to LED lighting.
Are dimmable lights more expensive?
Dimmer switches do have a higher initial cost compared to standard ones. Additionally, they require compatible light bulbs that can also be a bit pricier than average. LED light bulbs are the most popular bulbs on the market, but it’s important to buy bulbs that work with dimmer switches.
Why does my dimmer not dim all the way?
One of the most apparent reasons for dimmer switches not being able to dim all the way is the lack of compatibility between the dimmer and bulb you have used. There are dimmable bulbs and non-dimmable bulbs; if you were to use a non-dimmable bulb with a dimmer switch, it wouldn’t work out at all.

Do LED lights give off a lot of heat?
Do LED Lights Get Hot? Some marketing claims that LED lights don’t generate any heat, but this is not strictly true. Any appliance that uses electricity will generate heat, so all types of bulbs produce heat. However, LED bulbs consume far less energy compared to other kinds of bulbs, so they generate far less heat.
