What is CCFL?
Cold cathode fluorescent lamps (CCFLs) have a cathode element that is not independently heated. If sufficient voltage is present, electrons can be stripped even out of a cathode operating at ambient temperature. Most cold cathode devices use mercury or other hazardous heavy metal vapours for ionisation.
