The ccfl tube typically requires a fairly high voltage, i.e. a thousand volts, to become ionized. Afterwards, it operates at some few hundreds of volts. To achieve this operation efficiently, the inverters are designed to have an open circuit voltage sufficient to "fire" the tube. Then, a series impedance, typically a small, high ... kyrie irving father death
