What are C7 and C9 Lights?
C7 and C9 Outdoor Christmas Lights are larger than small mini-style Christmas lights and are often considered traditional outdoor Christmas lights. Traditional C9 and C7 Lights are heavier-duty than mini-lights and are more reliable. Christmas C7 and C9 bulbs screw into a candelabra base socket and can be replaced with standard Christmas bulbs called lamps. These “traditional” light strings are designed in such a way that if a single bulb fails, it only affects that bulb. Individuals often use C7 or C9 Light Strings to decorate large outdoor Christmas trees, outline building perimeters or simply to decorate the outside of their homes. Both C7 and C9 lamps or bulbs come in a variety of colors while the base socket and wire can be purchased in green or white.
