The HN-H-GX23-U-5W-8xx-G4 supports either line driven (120V/277V) or magnetic choke ballast driven sockets driven by 120V-277V / 60Hz.


In the line driven case (120V/277V), there are no known compatibility issues.

In the ballast driven case, as magnetic ballasts do not vary materially from vendor to vendor the way electronic ballasts do we do not generally encounter any ballast compatibility issues with the GX23 lamp.
