Why are dimmable LED lightbulbs not suitable for use with dimmers?
In: 5
LED lights do not dim in the same way as traditional incandescent lights. With at traditional incandescent dimmer it will gradually reduce the amount of electricity flowing through the circuit and as a result through the filament of the bulb, reducing how brightly it glows. But an LED only functions properly in a fairly narrow band of current, instead achieving dimming by being switched on and off extremely quickly. If done rapidly enough the human eye cannot tell it is flickering and instead just perceives the average amount of light being produced. If used with a traditional dimmer the LED will just abruptly stop working when the current becomes insufficient.
