Replacement Bulb Info
Replacement Bulbs come in two flame colors (white and yellow), each with different colored bases to match the candle color.
For both white and yellow replacement bulbs, specify either a white or off-white bulb base. Antique Gold and Pewter Candle holders have white candles, specify white replacement bulb base to match; Bronze Candle holders have an off-white candle, specify the off-white replacement bulb base to match.
