Advance Fluorescent Ballasts Labels 101

About Advance Ballasts and Fluorescent Lamps

Advance Ballasts that utilize fluorescent lamps usually come in two shapes, straight and u-shaped. Most fluorescent types are T5, T8, and T12. The T stands for tubular and the number provides the diameter in 1/8 of an inch. Lamp diameter is determined by ballast type. Therefore, a T12 ballast must use a T12 bulb. A T5 ballast must use a T5 bulb and so forth.

Please note T12 fluorescent tubes have been discointuned due to their poor energy efficiency. Sometiemes, you can find old stock in stores, but they are quickly becomes replaced with more efficient ballasts, such as a T8 electronic ballast.
