Battery operated, flameless Luminara Pillar Candles: Pillar Candles are typically candles with a wide base, so a candle holder is not necessary. Our flameless Luminara Pillar Candles are available in 3.5-inch and 4-inch diameters, and in heights of 5-inches, 7-inches and 9-inches. The candle is made of real wax. You can select from a variety of lovely colors and scents, perfect for all seasons and any occasion! The candles use two "D" batteries, and have five-hour timer features.
