HID lighting fixtures are reliable and long lasting; however, these fixtures are generally not easily accessible, meaning they are difficult and expensive to service. All the components to service an HID fixture are conveniently packed into one handy box, ensuring the job gets done all at once: Lamp. Prewired ballast. Capacitor (if required). Ignitor (if required). Mounting bracket. Hardware. Benefits: Simplified installation. Convenience of an all-in-one solution. Eliminate lamp and ballast compatibility issues.
