Not all LED bulbs are engineered to the same specifications. In some cases, flickering may be experienced when an LED bulb is not able to operate at the lower end of the dimming range. To improve performance, digital dimmers incorporate a minimum adjustment feature that is accessible through the app. Users can raise the lowest possible dim level to “trim” out any flicker issues.
The Dimmable CFL works on a different technology than incandescent or LED bulbs. The dimmable CFL may require an additional “kick start” or automatic adjustment to turn on. In this case, the dimmer will need to be set to CFL mode. Please refer to the device instruction sheet for details.
