In 1939 the name of the company was changed to Sperti Products, making both
medicine and sunlamps. Soon the lamp making business outgrew the initial facilities
and was relocated to larger quarters in Cincinnati. The ultraviolet tube was changed
to what was called a high pressure mercury vapour arc lamp and this sunlamp
became Sperti's primary product.
