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.
How do I know if my dimmer 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.
How many LED lights can I put 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).
Do LED lights require a special dimmer switch?
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.
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.
How do you make LED lights dimmer?
LEDs cannot be dimmed like light bulbs, by simply varying their input voltages. Instead, the current running through them must be directly controlled either by a resistor placed in series with the LED or by more advanced methods like constant current regulators.
Are LED dimmer switches different?
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.
How Low Can LED lights be dimmed?
In general most common mains LED bulbs will not dim below 10% and in a number of cases won’t dim below 30%.
How do I choose an LED dimmer?
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.
