It is shown that a gas absorber placed in the discharge volume of a mercury high-frequency electrodeless lamp (HEL) allows one to increase significantly its operational stability and service life as well as to decrease essentially the consumption of expensive mercury isotopes. A setup for measuring the HEL radiation intensity in the 253.7-nm line is described. The measurements of the HEL relative intensity as a function of the period of its continuous operation are discussed.
