1. In a lightweight portable ultraviolet germicidal lamp for killing both airborne and surface carried bacteria comprising a housing structure having side walls, a top wall and an open lower end;
- a grid spanning, lengthwise and widthwise, the open lower end of said housing;
support means at the lower end of said side walls to support the housing and permit easy movement thereof over a surface with the grid closely adjacent to said surface;
a reflector closely spaced from and facing said grid, said reflector carried by said housing and spanning between opposite side walls thereof;
a plurality of ultraviolet germicidal lamps intermediate said reflector and grid extending lengthwise of said housing and parallel to said lengthwise grid; and
handle means on said housing to permit the same to be readily moved by a user;
the improvement comprising,a detachable base section having a lower wall and upwardly projecting front, rear and side walls to removably engage said housing structure and support the same with said grid spaced from the lower wall of said base section;
openings in said front and rear walls to allow air to be drawn into a space between said grid and said lower wall; and
a fan carried by said rear wall to draw air through the space between said grid and said lower wall whereby any bacteria carried by the air is exposed to said ultraviolet lamps.
