Description: Fluorescent wear in a tube that was turned on and off regularly. The metal forming the cathode sputters and then vaporizes, , quickly adhering to the cooler glass surrounding the electrode. This forms a darkened area on the glass from the metallic deposits. The sputter eventually destroys the electrodes, increasing their work function until the lamp can no longer start.
