White & Color lamps come in many different kinds. What they all have in common is that they can emit all shades of white light, as well as light in all colors. There are starter packs with E27 light sources, but also with spots. These light sources are also sold separately. The White & Color lamps are dimmable using switches or the app. In addition, they can be synced to music and movies and you can set light schedules and light formulas with most brands.
