Review on 💡 OSRAM 73742 SYLVANIA SMART+ ZigBee Adjustable White RT 5/6 Recessed Lighting Kit - Compatible with SmartThings and Alexa Echo Plus, Requires Hub for Alexa and Google Assistant Integration by Kris Wagner

As I said, I think there are only two real downsides to these recessed lights: 1. They don't retain the last setting like other branded lights offer after a power switch. So if you want a night light setting or scene, be prepared to close your eyes as they return to their default brightness and then dim.2. When off, the built-in lights still have a faint glow that can be seen in the dark. When I look at the Zigbee traffic, it shows it's off for status and 0% for brightness, so it's probably a small problem with the dimmer with the lamp electronics, not the Zigbee messaging itself. A19 (Standard bulbs) with the same range work great and don't show this glow problem. I use mine with a GE Z-Wave Plus light switch and a SmartThings v2 hub.
