However, they do not always have to contain real candle flames, as this poses a risk of fire at any time. Therefore, the LED candle Clara is recommended not only for public buildings such as authorities, kindergartens, schools, or hospitals, as it creates a cozy atmosphere with its soft, warm white light. The LED candle Clara requires two AA batteries for operation. The batteries are not included and can be purchased separately. A remote control can be ordered separately. Built-in timer: 6 hours on/18 hours off.
