The versatile full-body UV-irradiation unit. The irradiation unit of the dermalight® 1000 is continuously slewable by 180° and enables therapy in standing, lying and sitting position. But also local treatment, f. ex. in the neck area, can be carried out without problems. The continuous height adjustment grants always the correct treatment distance. The moveable tripod of the unit grants an easy movement to the treatment place and a space-saving storage.
