A:Answer Thank you for considering Cync! Our Smart Lights require electricity to power them; weather that be an in-ceiling light, or a lamp plugged into a wall. So long as your sconce has power you should be able to utilize our bulbs. A member of our team would be happy to answer any additional questions or concerns. Please feel free to reach out to us directly, that is what we are here for, we want to help! Our phone number is 1-844-302-2943. -Cync Support
