Fluorescent and high-intensity discharge luminaires require a ballast to regulate the electrical current. Incandescent luminaires do not require a ballast. High-intensity discharge luminaires also require a ballast, but this option is not the best since it does not include fluorescent luminaires, which are commonly used in commercial and residential lighting.
