Does A21 bulb fit A19?
No, an A21 bulb cannot fit in an A19 lamp holder. This is because some A19 lamp holders are not compatible with larger bulbs due to space limitations. Another reason is that A21 bulbs may have higher wattages which produces more heat closer to a lampshade. This can lead to a fire.
A19 bulbs, on the other hand, can fit into A21 lamp holders if they share the same base. Make sure it is safe to do so before fitting the lamps. If the output of the fixture is higher than the bulb, do not install the bulb.
What does A21 mean on a light bulb?
An A21 light bulb describes the size and shape of the bulb. ‘A’ tells you that the bulb is pear shaped. The number ‘21’ describes the diameter of the bulb in eighths of an inch. In this case, the diameter of the A21 bulb is 2.625 inches.
