I saw this on Amazon a little while back:
Two CMARS RGBW bulbs along with an outlet for $35.99. They're all zigbee 3.0 - and I know the outlet works with Hubitat just fine.
The bulbs are also zigbee 3.0. That Amazon page has a terrible description, but I know that they are RGBW bulbs that support color temperature from warm white to cool white, based on folks using them with zigbee2mqtt.
They were marked as $8.00 off today, so I ordered all three. Will update this post to indicate if the bulbs work with Hubitat and what the color and color temperature look like.
