There is a risk of electric shock and fire with this project! Light bulbs are essential devices in our lives. Incandescent and fluorescent light bulbs are typical light bulbs for household lighting fixtures. For industrial and public purposes such as street lighting, large indoor lighting, sports field lighting and any outdoor activities, apart from these bulbs, HID (High Intensity Discharge) lamps are also widely used. Typical HID lamps used for this purpose are high pressure sodium, metal halide, and mercury lamps. The last one has been banned in 2021 by the Minamata Convention on Mercury. Fixtures with incandescent and fluorescent bulbs, long used for home lighting, became obsolete within 10 years of the widespread adoption of LED lights, and currently offer only replacement bulbs. Low-wattage HID lamps are also gradually being replaced by LED lamps. High-wattage HID lamps still dominate the mainstream of large-scale lighting because the advantages of LED lamps at this level are smaller. Like many LED geeks, I built an LED fixture because it was rare, but when it became commonplace it stopped being fun. On the other hand, my nostalgia for the disappearance of glass tubes from our lives increased and I started collecting HID lamps as a light bulb geek. However, having only light bulbs makes no sense. In order to light a HID lamp, a lamp ballast rated for each bulb is required. Therefore, I designed and built an electronic HID ballast that can light a variety of HID lamps.
