With incandescent bulbs, dimming is simple, since the brightness of a the bulb is straight related to the voltage applied. Adjust the voltage applied by elevating or reducing the dimmer and the brightness of the bulb will change accordingly. The same is not all the time true with LEDs, nevertheless. Would not turn on at all. Only works at one hundred percent brightness. Turns on but hums or buzzes loudly. Flickers at particular or all dimmer ranges.

If it isn't labeled as dimmable, it's secure to assume it is not. Whereas some LEDs work simply high-quality with conventional incandescent dimmers, it is prompt that while you improve to LEDs, you should also improve to LED-specific dimmers. Whereas a non-dimmable LED may perform nicely in a circuit with a dimmer swap (incandescent or LED) set to one hundred percent, there's an opportunity the light will flicker and hum at different brightness levels. Additionally, it might dramatically shorten the life of the bulb. Smart bulbs are usually not meant to work with dimmer switches of any type. They've a constructed-in dimming mechanism that will conflict with a wall-mounted dimmer and cause the bulb to flicker, hum or just not turn on. It is best to use the app or included distant to dim them instead.
