Place these battery-operated triple candles anywhere, then set the timer with a twist of the bulb. They'll turn on automatically for 8 hours and off for 16. There's no photo sensor requiring window lighting and no messy electrical cords. Cool, long-lasting yellow flame LED bulbs are included and never need replacing. Candle holders have white candles, choose white replacement bulb base to match, bronze candle holders have an off-white candle, choose the off-white replacement bulb base to match.
