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.
Is there a difference between a dimmer switch and a LED 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. A dimmer for LED lights is specially designed to send power and control signals to each type of electronic LED driver.
What size dimmer switch do I need for LED lights?
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 happens if you don’t use an LED dimmer switch?
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.
Can I use my old dimmer switch with LED bulbs?
In many cases, a typical dimmer switch (now called a legacy dimmer in the electrical industry) won’t work properly, if at all, with CFL or LED bulbs. Legacy dimmers were designed to work with incandescents, and CFL and LED bulbs bear no electrical resemblance to these types of bulbs.
How can I tell if my dimmer switch is LED compatible?
Check Your Existing Dimmer 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.
Can all LED lights be dimmed?
The answer is simple. Yes you can dim LED, but not all LED bulbs are dimmable. How does dimming a LED bulb work? The luminous element in a LED lamp is a LED.
Can dimmers damage LED lights?
The simple answer is yes – there can be a fundamental incompatibility between the LED driver and the dimmer which leads to spurious and often very large current pulses into the driver. Oscillogram 1 shows the measured LED voltage (red) and current (yellow) of a GU10 LED lamp being dimmed with an incompatible dimmer.
Can I put a dimmer switch on any light?
A dimmer switch can be installed anywhere that an existing on or off switch is in place. Replacing the current toggle switch with a dimmer switch will allow you to change the lights’ brightness, so long as you are using a light bulb that is compatible with the dimmer you have chosen.
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.
What makes LEDs dimmable?
In the case of PWM, dimmable LEDs work by creating a dimming effect. Unlike traditional lighting such as incandescent, dimmable LED bulbs don’t rely on voltage to dictate their level of brightness. Instead, they essentially rely on a cycle of being on and off.
Why are LED bulbs 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.
Do incandescent dimmers work with LED?
It’s impossible to tell whether your dimmer works with LED bulbs just by looking at it. Leading edge dimmers- these dimmers were designed to work with incandescent bulbs and most likely won’t work well with LED light bulbs. They’re the “traditional” and most common dimmer found in homes.
What type of dimmer switch do I need?
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.
How do you dim LED lights without a dimmer?
You just simply replace your current bulb with the SceneChange bulb, then you can just toggle your existing light switch on the wall or on a lamp to change the light setting. You can simply adjust the light from cool white to warm white to a warm glow with different brightness.
