An instant start F96T12 lamp measures how many inches in length?

The correct answer is: 96

The correct answer is that an instant start F96T12 lamp measures 96 inches in length. The designation "F96T12" indicates that the lamp is a fluorescent tube where the "F" stands for fluorescent, "T" specifies that it is a tubular shape, and the number following the "T" (which is 96) represents the length in inches. The "12" indicates that the lamp has a diameter of 12/8 inch, or 1.5 inches (which is a standard size for this type of lamp). This understanding is key when working with lighting fixtures, as knowing the correct length of the lamp is essential to ensuring proper fit and compatibility with fixtures and sockets designed for specific lamp types. The other options (9, 12, and 48 inches) do not correspond to the size designated by the "F96" specification, which clarifies why they do not represent the correct length of the F96T12 lamp.
