Do I need a special dimmer switch for LED light bulbs? While most LED bulbs are now dimmable, not all of them are and not all of them dim in the same manner Since LEDs consume such a low wattage, many types of dimmers do not function with LED in the same way that they do with high wattage load incandescents.

.

Similarly, you may ask, do you need a special dimmer switch for LED lights?

Because of their circuitry, LEDs are not always compatible with traditional dimming switches. If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer.

Secondly, what happens if you put a non dimmable LED bulb in a dimmer? If you install a non-dimming LED bulb in a circuit with a dimming switch, it will likely operate normally if the dimmer is at its 100% or fully on. Dimming the bulb, will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.

Accordingly, can I use a normal dimmer switch with LED bulbs?

A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.

What type of dimmer switch do I need for LED lights?

The type of dimmer switch and it's minimum/maximum load range will indicate the compatibility with LED light bulbs. Trailing edge dimmers work best with LED light bulbs and leading edge dimmers work best with traditional incandescent and halogen light bulbs.

Related Question Answers

Why do my LED lights flicker on a dimmer switch?

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.

Do LED lights get brighter the longer they are on?

LED bulbs do last a lot longer than the average light bulb, but no, they won't last forever. But remember that our LED light bulbs will keep shining almost as brightly as they did when new for most of their lifetime whereas many other brands start to noticeably fade even after a year.

Why can't LED bulbs be enclosed?

Using an LED bulb in an enclosed fixture when it isn't designed for that may cause the bulb to overheat, potentially causing damage to the light bulb and fixture. Even a little extra heat can shorten the lifespan of the bulb and keep you from enjoying the full value of your investment.

Can LED lights be left on 24 7?

I would not use an assemblage of parts that is not safety rated overnight or on a 24–7 basis. The luminaire and lamp need to be safety rated. Basically: Yes. LEDs consume far less electricity than either incandescent or fluorescent lights.

How do I know if my LED is dimmable?

Look for an "LED" or "LED LAMP" marking on the bulb as well. Most residential LED light bulbs are dimmable, but some are not. In addition, the amount they can dim, or “dimming range”, also varies based on the light bulb used.

Can you use a standard dimmer switch with LED lights?

LED light bulbs can be used in light fixtures controlled by dimmer switches, but you may well find that traditional dimmers may not work—or may work inadequately—with some LED bulbs. The bottom line is compatibility. Some LED bulbs are designed for use with standard dimmer switches, while others are not.

Why do LED lights need a different dimmer switch?

The main difference is that you have a smaller dimming range (typically 70-90% range vs. 100% with incandescent or halogen). LED Bulbs may not shut off at the lowest dim setting like traditional bulbs. This happens because the dimmer thinks the bulb is completely off due to the low amount of wattage the LED consumes.

What is an LED compatible dimmer?

Dimmer Switches work by reducing the power delivered to your light bulb. They do this by trimming a section of waveform, either on the leading edge or trailing edge of the wave. Manufacturers have designed their LEDs to be compatible with the majority of common 'trailing edge' household dimmers.

What is the difference between leading and trailing edge dimmer?

Leading edge dimming cuts of the front edge of each waves' half cycle. Conversely trailing edge dimming cuts out the second half of each waves' half cycle. Trailing edge dimmers are now the more popular of the two types.

Why are my LED lights not bright?

When this happens there is a large drop in voltage. When surge wattage occurs, the power drain can make the LED lights dim or flicker. A solution to this is to put all appliances on separate breakers as this will lessen the surge wattage. The dimming or flickering of LED lights will probably occur no matter what.

How many lights should be on a dimmer switch?

As an example – if you have a dimmer switch with a maximum rating of 400W (rule of thumb translates to 40W) you can run five 7.1W dimmable LED light bulbs (see example below for further explanation).

Are LED lights bad for your eyes?

LED light can damage eyes, health authority warns. The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week. LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness.

Can I install a dimmer switch on any light?

Most dimmers are designed to fit a standard wall box opening, which makes it easy to replace the switch for any incandescent or halogen light with a dimmer. With a three-way dimmer, you can control a light with two switches. You will need a three-way dimmer and a three-way switch.

Do not use with dimmers?

A: No. A CFL that is not specifically designed for dimming should not be used on a dimmer. The CFL may flash or flicker and the reliability of the CFL or the dimmer may be reduced. In 2010, Underwriter's Laboratories published the results of a study that examined the use of non-dimmable CFLs with dimmers.

Do dimmer switches cause fires?

The most common fire caused by dimmer switches is putting too much power through them. CLICK HERE to read about a dimmer switch fire. Modern dimmer switches use slick internal electronics to dim the lights. These components can turn the light on and off 120 times per second.

Can LED lights burn out?

LED lights do burn out, but at least in theory they should last far longer than incandescent or fluorescent lights. An individual LED may well last 100,000 hours, but it only takes one of those diodes failing before the bulb can be considered to no longer be working properly.

Do you need special bulbs for dimmers?

The packaging will indicate if an LED bulb is dimmable and will include a list of the types of dimmer switches that will work with the bulb. One of the most utilitarian bulbs, incandescent bulbs work with any dimmer switch on the market. However, if the voltage is too strong, these bulbs may burn out.

Can I use non dimmable LED on dimmer?

Dimming LED lamps can save energy and changes the visual appearance and mood of your space. You can use a dimmable LED lamp in a non-dimmable circuit. You should NOT use a non-dimmable lamp in a dimmable circuit as it may cause damage to the lamp and or circuit.

Can non dimmable LEDs be dimmed?

Dimmed lights mean a reduction in energy consumption and the best part is that you can use dimmable LED lamps within a non-dimmable circuit. It should be noted that non-dimmable lamps are not designed to work in a dimmable circuit as both lamp and circuit may get damaged.
