A15 light bulbs are smaller than a regular light bulb that you would use in a home. They are made smaller to fit into ovens, refrigerators and tight spaces and even ceiling fans many times. The neck is shorter and the bulb portion is smaller than the common style A19.
Also, older fluorescent bulbs were T12. Then, we had combination of magnetic ballasts and T12 bulbs. As I said, they lost to electronic ballasts and T8 bulbs. You simply may look at the numbers on the bulb to see if you have older T12, or newer T8 bulb.nother way, T8 bulbs are smaller in diameter (1 inch) in comparison to T12 (1.5 inches in diameter). To find the diameter simply divide the number by 8 and it gives you the diameter of the bulb. EX: T12 12/8=1.5 inches. As I said older T12 bulbs and magnetic ballasts come together.
