Our Everlasting Glow Pillar has a flickering LED, for a warm candle glow without the flames. The resin candle has a wax coating and is worry free. The built-in timer switches the candle on for five hours and shuts it off automatically for 19. It will relight at the same time every day! It uses 3 "AAA" batteries which are included. It can be switched on and off manually if you desire. It is 4-1/2" tall and has a 3" diameter. It can be used indoors or out.
