Today I show you a General Electric nema head that was originally 175 watt that's been converted to a 100 watt #streetlights #mercuryvapor #generalelectric
Since you don’t show the actual bulb and ballast in the video, I think you actually have a metal halide lamp and ballast in your fixture. The incandescent glow you are seeing would be the two electrodes, one at each end of the arc tube. Mercury lamps will usually look green on video. This lamp looks white like metal halide. A 100-watt metal halide lamp requires a pulse-start ballast, so if your ballast has a cap and ignitor, it is PSMH.
