Abstract
A fluorescent lamp having multiple zones with different ultraviolet radiation characteristics along its length has a tube with a first fluorescent coating for producing ultraviolet radiation of substantially uniform intensity extending over a first finite length of the tube adjacent one end. A second fluorescent coating extending over a second finite length of the tube adjacent its other end thereof produces ultraviolet radiation of a substantially uniform intensity and having radiation characteristics which are different from those produced in the first finite length. Generally, the UVB intensity and UVB/UVA ratio will be increased. This lamp is ideally suited for use in tanning chambers to provide uniform tanning by providing a higher intensity and a higher UVB/UVA ratio for radiation in the area of the head.
