Gotta try this, I made one with a light bulb and it had a very gross taste to it. I did my best to clean it and get the glue off that is attaching the metel to the glass . I think this is the taste, if your gonna use a light bulb if you carefully removed the metal and stuck a Glass on glass converter in there, and then used a non diffused down stem as the stem. Gonna try this but gotta get a new stem and try to find a bulb with a thicker stem to support the converter.
