You may use a wall dimmer to control the brightness of an Element Plus bulb.
However, our Element Classic bulbs will NOT function properly when they are dimmed via a wall dimmer switch. If you do use them on a wall dimmer switch, the bulbs will flicker and cease to be controllable through the app. If this happens, you must reset and re-add the bulbs to your hub before they can be controlled again.
Element Touch will work normally (i.e. won't flicker) when connected to a dimmer switch, but it cannot be dimmed via the switch. You will still be able to adjust its brightness via the button on the body of the bulb.
