CBMA, which stands for Certified Ballast Manufacturers Association, is an organization within the lighting industry that specializes in certifying ballasts according to the standards set by the American National Standards Institute (ANSI). The primary purpose of CBMA is to ensure that ballasts meet the required criteria for quality and performance. Ballasts that receive the CBM seal of certification are guaranteed to have a minimum ballast factor of 0.85, which is a measure of the efficiency of the ballast in regulating the flow of electrical current to the lighting system.
