Element Plus: Quickly turning the bulb off and then on via a wall switch will allow you to set the brightness without using a mobile device or hub. After turning the bulb off and on quickly, it will begin cycling from its lowest brightness level to its highest brightness level. When it reaches your desired brightness level, turn the bulb off, wait a few seconds, then turn it on again using the wall switch and it will remember this setting.
Element Touch: Pressing the button on the face of the bulb will cycle through its four brightness and color temperature settings.
Element Classic: There is no way to set the brightness of Element Classic bulbs without the use of a mobile device.
