The XIRIS lamp produces a mix of radiation very similar to that of natural sunlight and can have the same positive effects on the body as the sun. This blend of radiation is generated by a quartz discharge tube and a tungsten filament. The bulb is made of special glass which allows only that part of the output that is contained in natural sunlight to pass through.
Ultraviolet radiation has various biological effects on humans. Some of the most important ones are listed below.
-Direct pigmentation
-Long-term pigmentation
