This is an old 100W Mercury Vapor bulb that I found it in a trash can. It was already broken, so I finished the job and notice that it used to be a self-ballasted one with no ballast required, but the outer bulb was gone, and I just can't run naked the filament (anyway, it was broken as well). If I wanted to run it, I need to twist the main electrode cable of the arc tube to the line cable. So I did it and now, following the proper protection protocols, I can run this thing safely (more or less). ⚠️DANGER⚠️ DO NOT ATTEMPT TO RUN A MERCURY VAPOR OR ANY TYPE OF HID NAKED ARC TUBE WITHOUT A PREVIOUS PROTOCOL OF PRECAUTIONS AND THE PREVIOUSLY KNOWLEDGE. NOT FOLLOWING THIS INSTRUCTIONS CAN CAUSE A SERIOUS EYE INFLAMMATION OR SKIN BURN BECAUSE OF THE SHORTWAVE ULTRAVIOLET RADIATION EMITTED.
