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.
The life of a 48-inch fluorescent light bulb, technically called a fluorescent lamp, depends upon its wattage, design and application. A typical 32-watt, 48-inch fluorescent lamp will burn for about 20,000 hours, if normally left on for about three hours at a time. The same lamp, left on 24 hours a day, will last about 34,000 hours.
