What is the difference between 922 and 921 bulbs?

Answer 1

The main difference between 922 and 921 bulbs lies in their design and application. The 921 bulb typically has a higher wattage output, making it brighter, while the 922 may have a lower wattage and is often used in applications requiring less intensity. Additionally, they may have different base configurations or sizes, making them incompatible in certain fixtures. Always check the specifications of your fixture to ensure compatibility.
