Most dimmable smart light switches will work with LED, CFL, and incandescent bulbs. You'll just need to make sure that the switch is compatible with your home's wiring. For example, if you have a dimmer switch that uses a low voltage system, you won't be able to use it with LED bulbs. nnIf you're not sure whether your home's wiring is compatible with a dimmer switch, it's best to consult with a professional electrician. They'll be able to help you choose the right dimmable smart light switch for your needs.
