What is C9 Bulb

A C9 bulb is a type of light bulb, particularly during the Christmas season. It is characterized by its larger size compared to other Christmas light bulbs, such as C6 and C7 bulbs. A C9 bulb typically has a diameter of 1 14″ and a height of 2.5″. One notable feature of C9 bulbs is their higher wattage, which can be up to twice that of C7 bulbs, making them more powerful in terms of brightness and illumination.

C9 bulbs are often favored in commercial settings due to their ability to create a visually striking impact. They are frequently used to outline rooflines, both in commercial and residential environments, adding a festive touch to buildings and structures. The larger size and higher wattage of C9 bulbs contribute to their ability to produce spectacular lighting effects, making them a popular choice for creating dazzling displays.
