This is product is discontinued and replaced with the ZEN74. What does that mean?

Flickering lights? There may be a driver incompatibility between the bulb and dimmer. 

The executive element in ZEN24 Toggle Dimmers is TRIAC, a leading edge driver. If an LED bulb uses a trailing edge driver, this may lead to flickering.

To fix the flickering issue, we'd recommend either adding a bypass to the load or trying a ZEN27/ZEN77 dimmer since these models use a MOSFET (trailing edge / ELV dimming). Please note: the ZEN27 and ZEN77 are paddle models, while the ZEN24 is a toggle dimmer.

Another detail to check is if the LED bulbs you're using are labeled as dimmable. Regular on/off 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.
