Do you need a special type of dimmer switch for LED lights?

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.

Do you need a special dimmer to dim LED lights?

Yes, LED lights require a special dimmer. An old fashioned incandescent dimmer switch will not work properly with LED bulbs. You cannot just simply lower the voltage to the LED driver.

What kind of dimmer is needed for LED lights?

LED bulbs have a low wattage, so you’ll need to have a dimmer that is 250W or 400W and ideally intelligent trailing edge, for smooth dimming. See our full range of LED suitable trailing edge dimmer switches.

What is the difference between magnetic and electronic low voltage dimmers?

Dimmers for use with magnetic low-voltage transformers use a technology known as standard phase control or “leading edge,” where as dimmers for electronic low- voltage transformers use reverse phase control or “trailing edge.” Standard phase control is for use with either inductive (MLV transformers, fans) or resistive

How do I choose an LED dimmer switch?

Choose a dimmer with a wattage rating that meets or exceeds the total wattage of all the light bulbs the dimmer will control. For example, if the dimmer controls a fixture with ten 75-watt bulbs, you need a dimmer rated for 750 watts or higher.

Can you put a dimmer on LED strip lights?

Is all LED tape dimmable? Yes. Every product in InStyle’s LED tape range is dimmable. LED strip lights are dimmable only if wired to a suitable dimmable transformer or controller.

Why do LED lights flicker on dimmer?

LED bulb flickering can be traced in almost every instance to a non-compatible dimmer switch in the lighting circuit. Modern dimmer switches create the dimming effect by switching the power supply on and off many times per second.

Why do LED lights hum with dimmer switch?

Almost every time the reason for LEDs humming when used with a dimmer switch is when the bulb’s power supply, aka driver, is incompatible with a dimmer system. It is actually the solid-state driver making the buzzing noise, and not the lighting emitting diode itself.

How many LEDs can I put on a dimmer?

A rule of thumb commonly used to calculate a load for LED dimmers is to divide the stated maximum load by 10. For example a 400W dimmer switch should have no more than 40W of LED bulbs connected to it, which would equate to eight 5W bulbs.

What is magnetic low voltage dimmer?

Magnetic Low-Voltage Dimmers



Magnetic Low-Voltage (MLV) dimmers control MLV transformers and are suitable for recessed lights. MLV lights tend to be larger and heavier than ELV lights.

How many watts should my dimmer switch be?

Dimmer Wattage



You should select a dimmer based upon your wattage requirements. The easiest way to do this is as follows: – Add up the total wattage of the bulbs you wish to control. For example, a fixture with four 60W bulbs has a total wattage of 240 (4 bulbs x 60 watts).

What are three types of dimmers?

Different Types of Dimmers

  • Incandescent/Halogen. These types of bulbs require resistive dimmers due to the filaments inside of them. …
  • Magnetic Low Voltage (MLV) Transformers that reduce higher voltages to less than 30 volts are called low-voltage transformers. …
  • Fluorescent. …
  • Light Emitting Diode (LED)


Are low voltage LED lights dimmable?

Quote from the video:
Quote from Youtube video: They generate a straight DC output ranging from 8 to 12 for 16 to 24 volts depending on the model. By reducing DC voltage the current and the LED strip Falls dimming the lights you.

Do I need an ELV dimmer?

Standard rotary or basic slider dimmers will do for basic bulbs. Incandescent low voltage systems, like rail systems, have transformers that may require an ELV dimmer to protect the driver. Many states have put bans on standard incandescent bulbs.

What voltage should a dimmer switch be?

The dimmer switch is rated for the same voltage as the lighting application. Use standard dimmers on 120 line voltage and low voltage dimmers for 12V and 24V applications.

Why do some dimmers not work with LEDs?

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.

Can you put a dimmer on 12V LED lights?

The 2-in-1 LED Dimmer must be wired between a 12V DC power supply and the 12V DC LED lighting. Failure to observe polarity or shorting wires may damage the dimmer and LED lights. Wire runs inside walls must be installed in accordance with national and local electrical codes, low voltage Class 2 circuit.
