GE now has four smart bulbs. So when you look at deals, make sure you know which of the four it covers.
Two from the “GE Link” line use Zigbee and are compatible with SmartThings (“soft white” and “daylight”).
Two from the new “C by GE” line use Bluetooth and are not (“Sleep” and “Life”).
The “Daylight” Zigbee bulb has a blue bar on the package, but it is still Zigbee, not Bluetooth, and will pair with SmartThings although you will to manually change it to device type for the original soft white bulb.
