Abstract	Study of radiation parameters and lifetime period of the manufactured barrier discharge excilamps has been performed. Average power of radiation for the just sealed off KrCl (λ ∼ 222 nm) excilamp exceeded 100 W was obtained. The emitter with length of 1200 mm at external diameter 65 mm was tested. Length of a radiating surface has made 1100 mm. The tests were carried out with air cooling system. Maximal radiation power density was of 50 $mW/cm^{2},$ that corresponds to excilamp radiant power more than 100 W. UV output power of ∼75 W and efficiency up to 10 %, respectively, at λ ∼ 308 nm (XeCl* excilamp) were obtained under excitation by pulses with frequency of 100 kHz. Application of water cooling allows increasing the radiant emittance of DBD coaxial excilamps. It was noted that in the coaxial quartz tube KrCl - excilamps excited by a barrier discharge, the maximum emission efficiencies are observed for a discharge in the form of diffuse cones. VUV output power of ∼120 W at λ ∼ 172 nm was obtained under excitation by pulses with frequency of ∼100 kHz.
