@cag - I do have one more idea for you, but your GE C Life bulbs would need to be connected to a Google Home device (using the C Reach device).
If you have a Google Home device, and can control your bulbs via voice control, then there is a one-way option to have Hubitat control these bulbs. It isn't exactly pretty, but it is doable for the somewhat tech-savvy.
You would need to run a Raspberry Pi (or similar) on your home network. On this RPi, you can run a NodeJS server called Google Assistant Relay. This NodeJS server can accept http commands that mimic voice control of a Google Home device, using the Custom Command [CC] feature of my Google Assistant Relay Driver for Hubitat. Take a look at the following guide. Again, not for those who want a simple plug and play...and definitely not as reliable as just using one of the natively supported lighting options I mentioned above...but it is possible!
