Abstract: A lamp fixture includes a housing situated along a housing principal axis. The housing has a first housing end and a second housing end which are situated in opposed relation along the housing principle axis. A polycarbonate lens tube encompasses the housing about the housing principle axis and transmits light emanating from the at least one tubular fluorescent lamp. The lens tube is open at first and second tube ends. The first and second tubular ends are situated in opposed relation along the housing principle axis. A first endcap joins the first tube end to the first housing end. A second endcap joins the second tube end to the second housing end. When endcaps join the tubular lens to the housing, the resulting unit provides a light fixture for the at least one fluorescent tubular lamp.
