This product is poorly designed. I had a professional electrician install it and when he put the first bulb in, the metal on the bulb came into contact with the metal candle shaft and short circuited the whole thing, blowing out the two dimmer switches in the process! He fixed the switches but now the candle that caused the initial short won’t work! I don’t know if it can be fixed or if I’ll have to return it! What a pain!
