You don't always have to use real candle flames, as this poses a risk of fire at any moment. Therefore, the LED candle Clara is recommended not only for public buildings such as government offices, kindergartens, schools, or hospitals, but also for creating a cozy atmosphere with its gentle warm white light. The LED candle Clara requires two AA batteries for operation. Batteries are not included and can be purchased separately. A remote control is available for separate order. Built-in timer: 6 hours on/18 hours off.
