Q. Fluorescents? 
-
Fluorescent is a light source consisting of a tube filled with argon, along with krypton and other inert gas. When electrical current is applied, the resulting arc emits ultraviolet radiation that excites the phosphors on the inside of the lamp wall, causing them to radiate visible light.
-
Every lamp will contain a T number and an F number. The T indicates the diameter of the lamp and is measured in 1/8s of an inch. The most common Tnumber is 12 which translates to 1 ½ and is also known as the chubby tube.
Other T numbers that may be seen are;
T2, T4, T5, T6, T10, with T12 & T8 being the most common.
-
The F number indicates wattage and what length it associates with.
Following the T & F numbers, is any other pertinent information that indicates colour temperature, base and coating.
-
All fluorescents require a ballast to start up the lamp.
