Smart lights with an E14 fitting are lights that have a thin screw thread with a 14-millimeter diameter. These smart lights are also known as candle bulbs and you can recognize them by their elongated shape. Often, these lights are used in mood lighting or table lamps, places that don't need as much light. That means you mostly use E14 smart lights to make your mood lighting smart. All smart E14 lights are dimmable, but some models can also change to different colors.
