These beautiful candles have a very realistic flame effect that actually dances & flickers like a real flame but it's actually a safe LED, which means that there's none of the risks associated with real candles. The main body of the candle gently scrolls through various colours whilst the flame on top dances. Simple to operate by either on/off remote or with the timer switch on the bottom, once you switch to the 'on' position it will stay on for six hours, & then turn 'off' again for eighteen hours, meaning you can place your candle in hard to reach places & have it come on automatically at the same time every evening. Also a great home security item for when you're away from home! Available in three sizes. Remote on/off only Timer 6 hours on/18 hours off Colour changing wax body (cannot be set to a specific colour) Realistic flickering & moving flame Candle requires 2 x AA batteries (not included) Remote control requires 1 x CR2032 (included) Diameter 9cm/3.5" Available in small (13cm/ 5.25"), medium (18cm/7.25") or large (23cm/9.25")
