Nope, it's flipped it's spectrum end
I do know U/V light from 'roadie' work with several local bands, they used mercury-discharge bulbs that made everyone in the audience glow blue/white (nails and teeth) and turned white nylon transparent - hehehehehe
This PC tube was a beautiful deep purple colour fading to black, and all the fluorescent bits in my PC glowed from it. Now it's a dull ruby red - t'other end of the visible spectrum.
I'm not sure whether it's the power block or the tube itself that's faulty
