Hi, @Dwood.
Welcome to the Roku Community1
We appreciate you bringing this to us about having an issue with your smart bulb not turning on. We're here to provide some steps you can try.
Could you please try inserting the bulb into a different lamp? Let's see if that makes any difference.
We'll wait for your response.
Thanks,
The Roku Community Team
