The high CRI Philips Ultra Definition bulbs with a smart dimmer. I use them with a Z-Wave Leviton but there’s ZigBee options too if you don’t have a Z-Wave radio. Those bulbs make the most beautiful light… I use the warm ones 2700K or so because they’re the best for the eyes. It seems Cree and Feit also have high CRI bulbs but I haven’t tried them.
I second the smart switch strategy, especially when using a fixture with several bulbs.
As for ZigBee however, I’ve been using Home Assistant Yellow with its built-in ZigBee radio and ZHA, and it’s been flawless. Any issues I’ve have been a matter of reinforcing the network by adding a few smart plugs. I got over 60 devices hooked to it at the moment. Z-Wave has been just as problem-free. The really nice thing about having a Z-something network is the ability to use low power devices like battery powered sensors and switches/controls. Want a smart doorbell that plays a chime on all speakers and sends you a phone notification? Stick any ZigBee button to the outside of your door and program the automation. Its battery lasts two years.
