The results of a comprehensive investigation of electrical, spectral and power characteristics of a stationary source of radiation of a low pressure on ArCl, KrCl, XeCl and Cl$_2$ molecules are presented in this paper. A longitudinal decaying discharge of a direct current on mixtures He/Cl$_2$, Ar (Kr, Xe)/Cl$_2$, Ar/Xe(Kr)/Cl$_2$ and Ar/Kr/Xe/Cl$_2$ served as an active medium. A multiwave operation mode of the source of radiation was realized by means of using two or three components mixtures of heavy gases (Ar, Kr and Xe) with molecules Cl$_2$. The developed emmitter can be used in UV-VUV photometry, chemistry of high energies, biophysics and medicine. It was shown that the spectrum of a multiwave source of radiation overlaps the area of 170-310 nm at base lengths waves of 175, 199, 200, 222, 236, 258 and 308 nm. The power of radiation of the lamp on the mixtures Ar/Cl$_2$, Kr/Cl$_2$ and Xe/Cl$_2$ grew from 2 to 8 W on transition from the Ar of to Xe media. The optimum pressure of mixtures made 3-4 kPa, and $P$(Cl$_2$) = 0.25-0.40 kPa. The lamps on the mixture Ar/Kr/Xe/Cl$_2$ by power and effectiveness are very close to those on the mixture Xe/Cl$_2$. The greatest effectiveness ($η \le 25$ {\%}) of the source of radiation was achieved in a decaying discharge at small discharge currents $I_{\rm {ch}}\le 5$ mА.}
