At gas-discharge lamps the flask is filled with xenon gas, and light is created as a result of fire of an arch owing to application of tension between two electrodes. Electronic monitors and the source creating quickly tension 28.000 B for ignition of a light arch are necessary for work of a gas-discharge lamp. For creation of double luminous intensity of the 55 W usual lamp for a gas-discharge lamp enough power is 35 W.
