There are three types of LED bulbs used in chandeliers: Edison style, traditional globes, and chip-style. Edison style bulbs consist of a number of small bulbs arranged around a central incandescent bulb. Globes are the most common type of chandelier bulb and use a spherical body with a number of smaller bulbs inside it. Chip style bulbs are the smallest form of LEDs and look similar to traditional lightbulbs.
