UV-B lamps emit ultraviolet rays between 280nm and 360nm (at peak 306nm). The spectral energy distribution is suited to test the ultraviolet resistance of paints, plastics, and rubbers. They are also used as the special light sources for inspection and analysis.

Warning:
The radiation of these lamps is harmful to eyes and skin. Protect your eyes and skin against the ultraviolet rays.

The shape, structural, and electrical characteristics are similar to general fluorescent lamps used for illumination.
*1 After 100 hours of lighting
*2 When the ultraviolet ray output becomes 60% of the initial output (after 100 hours of lighting).
