Japanese 100V 50Hz National HD500 FCL32 preheat louvered circline fluorescent pendant fixture

I decided to import this Japanese 100V 50Hz National FCL32 preheat circline fluorescent pendant fixture from Japan to use as a swag lamp for my college dorm because it looks very unique by having a louvered diffuser on it, which is something that is not usually seen with circline fluorescent fixtures. In addition, I also decided to get this fixture because even though the fixture has a 100V 50Hz HX autotransformer ballast, it works very well on North American domestic 120V 60Hz mains supplies without the need for a step down transformer due to the fact that as you increase the applied supply voltage and frequency to the ballast, its inductive properties remain virtually the same since this fixture has no capacitors in the circuit. This means that the lamp current remains the same even on a 120V 60Hz mains supply despite the ballast being designed for eastern Japan’s domestic 100V 50Hz mains supplies. Later on in the video, I installed a North American 32W circline fluorescent lamp in the fixture to show proof that they are the same size as Japanese FCL32 circline fluorescent lamps. Sadly, I don’t have any European 32W circline fluorescent lamps in my collection even though I know that they are also the same size as the aforementioned circline fluorescent lamps as well but was not able to show proof.
