Some led bulbs are designed for use with standard dimmer switches while others are not.
Can led lights be used with a dimmer.
Not all led lights are designed with dimming capabilities.
Many online shops offer a sorting function where you can filter by dimmable lamps.
Some fixtures such as under cabinet and recessed lights may need special led dimmer switches for proper performance.
The bottom line is compatibility.
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 proportion of dimmable led luminaires is slightly smaller.
Check the box or product description first to make sure they re dimmable seen below.
Especially for led bulbs there is a huge selection of dimmable models.
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.
If you have to do this we suggest keeping the bulb at full power.
Existing dimmer switches often have a minimum power of 50w but because led lights tend to have lower wattages than the standard bulb when a bulb is connect to that dimmer switch it will not reach the minimum power required and would usually confuse the dimmer switch and the lights start to flicker make buzzing noise or overheat.
People often assume that they can use their normal and ordinary dimmer switch for led lights however this is not possible in many cases.
Unfortunately led loading cannot be calculated the same way as a traditional incandescent or a mains halogen light bulb.
Dimming the bulb will likely cause erratic behavior such as flickering or buzzing and ultimately may cause damage to the bulb.
A good rule of thumb to apply one that is used by most manufacturers is to take the maximum rating of the dimmer switch and divide by 10 or in other words use 10 of the max.
Make sure you have dimmable led lights.
So what happens if you use non dimmable leds on a dimmer.
