Hi @BuckeyeJoe,
Welcome to the Roku Community!
We are happy to have you here inquiring about the Roku Smart Bulb Color SE.
Yes, it is perfectly fine to use a Roku smart bulb in a lamp. You can simply control the brightness using the Roku Smart Home app on your phone and never use a dimmer switch.
For more details, you can visit our Roku Support article: Getting to know your Roku® Smart Bulb SE | How to set up your Roku Smart Bulb SE
We hope you find this information helpful.
Regards,
Riamie
