A Type A light bulb is part of a series of light bulbs commonly used for general lighting purposes. The most widely used Type A bulbs are A15, A19, A21, and A25
. These bulbs are typically compatible with medium screw bases (E26 and E27) or the candelabra base (E12)
. The A19 is the standard light bulb size, often used in household fixtures, hall lighting, and ceiling fans
. Some other types of light bulbs include:
- Type B and C : These bulbs are longer and have a tip at the end, resembling a candle flame. They are often used in decorative lighting, such as chandeliers and wall sconces
- Type BR : These bulbs include reflectors and bulged reflectors, and they are commonly used in outdoor floodlights or recessed lighting
- Type PAR : These bulbs are typically used as outdoor lighting and have a parabolic aluminized reflector (PAR)
- Type PS : These bulbs are pear-shaped with a rounded, oblong end, similar to Type A. They can be used indoors or outdoors in light fixtures designed for a bulb with a longer neck than Type A
- Type G : These bulbs are large and round, often used in a row on a vanity to provide bright light. They can fit in any standard fixture
- Type C7/F : These bulbs are candle-shaped and often used in night lights and holiday lights. The base of a C7 bulb is a candelabra size
