Lights Flicker with My ZEN72 Dimmer Switch

LED lights flickering might be due to driver incompatibility between the bulb and dimmer. 

The executive element in the ZEN72 Dimmer switches is TRIAC, a leading edge driver. If your LED bulbs call for a dimmer that uses a trailing edge driver, it could cause the lights in your installation to flicker.


There are a few ways you can resolve this if you'd prefer not to change the bulbs: you can add a bypass to the load or try a ZEN27/ZEN77 dimmer. The ZEN27 and ZEN77 dimmer models use MOSFET (trailing edge / ELV dimming).


Another important details is to make sure your LED bulbs are labeled as dimmable. On/off LED bulbs are not compatible with dimmers and will not perform correctly. 


Never use a Z-Wave dimmer with smart bulbs unless you disable paddle control on them first. Dimming smart bulbs from a wall dimmer may damage your equipment.


Send us a message if you have any questions about your ZEN72 Dimmer or your LED lights!
