KEYSTONE's extensive portfolio of electronic ballasts cover all fluorescent lighting application needs, including commercial, industrial and residential fixtures. Our latest electronic ballasts use a compact form factor design, enabling fixture manufacturers to design sleeker, more streamline fixtures. KEYSTONE offers fluorescent ballasts in a variety of case styles to power most standard lamps. KEYSTONE ballasts are burned-in at the factory to ensure both exceptional performance and superior reliability. Once each ballast is sealed and all assembly is complete, each unit is connected to the proper lamps and powered at full load for at least 1 hr. This burn-in testing eliminates virtually any manufacturing or component defects.
