Conventional ballasts need a starter: Older fluorescent fixtures with conventional electromagnetic ballasts require a separate starter to function properly. Electronic ballasts do not need a starter: Modern fluorescent fixtures with electronic ballasts can ignite the tube without a separate starter.
