Fluorescent lamps are generally in the form of
long cylindrical tubes which are suspended from
a housing by tube sockets which engage the ends
of the tubes.

The tubes are of standard lengths and‘it is the
common practice to build the housings to ?t the
different lengths of the tubes.
It is one object of this invention to‘ provide a

in Figure 7. In its main body portion, it is pro
several parts, except the lamp sockets which
project through openings in the cover member.
The base member is designated 2| in the draw

and side walls 23, the free edges of which are
vided with a lamp socket receiving opening 44
from which leads a slot 45 to receive a screw for
securing a lamp socket thereto.

In Figure '7 of the drawings, the lamp socket
supporting member 3?’ is shown in position to

side walls of the base member 2| and the in

The two end sections are of the same construc

This construction provides relative short ?ange

and in such cases, a lamp socket supporting mem- >

employed.
The lamp socket supporting member illustrated
in Figure 14, comprises a main body portion 15
which has two spaced socket receiving openings 16, each of which is of a size to receive a single
socket. Side ?anges "H are formed by pressing
side sections of the body portion out of the plane
of the main body portion as at 18 and these side
?anges are provided with openings 19. '
When this type of construction is employed, the
?anges 53 must necessarily be longer than illus
trated in Figure 10 and each must be provided
with two openings instead of one as shown in
said ?gure.
