Call the guy and ask him what size bulbs they are. Whether they are T5, T8 or standard NO lights. With the light range, it is doubtful they are NO (T12). The number with the T is the diameter of the bulb in 1/8" of an inch. So a T5 bulb is 5/8", a T8 is one inch, and a T12 is 1 1/2". A T12 is what you get for a shop light and is called "NO" (Normal output).
