Even though you have removed it, you should be able to do a general exclusion, which should also reset the bulb:
Exclusion (Factory Reset)
Before putting your hub/gateway in exclusion mode, remove power from the bulb (unscrew it, flip switch down, etc).
-
With power removed from your bulb, put your hub/gateway in exclusion mode
-
Restore power to the bulb and it should flash 2x indicating it’s in exclusion mode
-
If successful, the bulb should flash a third time
In ST, you’ll find the general exclusion under the hub’s Zwave utilities.
