T8 ballasts control the amount of electricity powering a T8 linear fluorescent lamp. Without a linear fluorescent electronic lighting ballast to limit the voltage or current across the T8 lamp, either the tube or the circuit will quickly fail. For commercial retrofits and installations, electronic T8 ballasts have become the preferred linear fluorescent lighting ballast technology, replacing the less-efficient magnet ballast in most applications. T8 electronic lighting ballasts also greatly reduce or eliminate harmonic distortion (lamp noise), flicker, or fluctuations in light output.

The T8 linear fluorescent lighting ballast is the most common type of ballast, offering a variety of ballast factor and wattage options to choose from. The T8 ballast is usually housed in the linear fluorescent fixture with one to four T8 lamps. Choose from 120- or 277-Volt T8 ballasts in wattages from 13 to 42 watts.

The right electronic ballast protects the light source from damage, and helps maintain consistently high-quality illumination throughout the life of the lamp.
