These special effect bulbs contain a little flame that moves and flickers with orange light. They are E12 fitting, which is also known as a small screw for chandeliers, and the style and shape of the bulb is CA10, which refers to the conical shape with bent tip. They are the perfect replacements for our Flicker Bulb String Lights but are also often used in candle bridges at Christmas, or chandeliers for an old fashioned real candle effect, although at only 1 watt of power they are more suited for the decorative special effect they produce, than giving off useable light for a room. You would often see this sort of bulb in mock fireplace lights, theatre productions, or as Christmas decoration.
