You can screw separate smart lights into existing fixtures. Choose a smart light that suits how you use the space: from warm white light for extra ambience to smart lights with colors for a party. When making your decision, pay attention to the fitting (like E27 or E14), the number of lumens, and if you want warm white light or colors. Lastly, check whether the smart light works with your smart home system and app, so you can easily control all your smart lighting in one go.
