Does dimming LED bulbs prolong life?
Since dimming, either by reducing current or by pulse width modulation, results in lower overall junction temperatures, it will have no negative impact on LED life; it might even extend life.
What happens if you try to dim a non-dimmable light bulb?
If you use non-dimmable LEDs on a dimmer, what happens? The bulb will not dim properly. The circuitry inside non-dimmable LEDs won’t be able to handle low or pulsing current levels and will eventually become damaged, because they are only designed to be either fully powered ON or off.
