The length of a fluorescent light bulb is measured from the back of the socket on one end of the bulb to the back of the socket on the other end. The bulbs are labeled according to the diameter and the length. Linear tubes range in length from 6 to 96 inches and fit into slightly longer fixtures.
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.
