With the Den system you don't need to use smart bulbs, as the purpose of our products is to move that control to the switch.
However, if you already have smart bulbs in your home then you don't need to replace them with standard bulbs. They will work in the same way normal bulbs will and you'll be able to turn them on and off via our App.
In addition, our dimmers will also be compatible with a wide range of dimmable LED, CFL and traditional filament bulbs. A list of compatible bulbs will be provided at launch.
