## Abstract

An integral housing for mounting and operating one or more elongated fluorescent lamps. The housing is frame shaped having a center arm with a section for holding the ballast transformer and a side arm at each of the ends of the center arm which have sockets for holding the lamps. The housing is preferably of two hollow sections for holding the ballast, wiring and various components and the sections are fastened together.

## Claims

### Claim 1

A fixture for a pair of fluorescent lamps comprising:
a housing of two complementary mating hollow sections each having a center arm and a side arm extending transversely from each end therefor to form a generally H shape, said center arm having at least a portion which is enlarged relative to said side arms,
means for holding said sections together,
a ballast transformer within the enlarged portion of said center arm of said sections,
a socket for accepting the terminal of a fluorescent lamp adjacent each end of each side arm to hold a fluorescent lamp both above and below said center arm between said side arms and spaced from said center arm, and
wiring for the fixture extending between said ballast transformer and said sockets within said housing sections.

### Claim 2 (depends on 1)

A fixture as in claim 1 wherein said housing sections are of molded plastic material.

### Claim 3 (depends on 1)

A fixture as in claim 1 wherein said sockets are located in said side arms inwardly of the ends of the side arms to place at least a part of each of the lamps inwardly of the ends of the side arms.

### Claim 4 (depends on 3)

A fixture as in claim 3 wherein the sockets are located on said housing side arms at positions such that the entirety of each of said lamps is located inwardly of the ends of the side arms and within the overall confines of the housing.

### Claim 5 (depends on 1)

A fixture as in claim 1 wherein the outer faces of said housing sections are generally planar.
