My UV cold cathodes don’t seem nearly as bright as they used to be, I really noticed this today when I looked a pic if my computer a year ago. I guess I could buy new ones, they were only like 20 from Frozen CPU with custom sleaving. Then again I don’t really mind it dim, its not overpowering and certainly not as annoying at night when sleeping. Could this also be caused by an increased draw on the power supply? I did not have my video card or as many hard drives back then.
