Finally, Exhibit 7 accompanying the motion is the
senior party patent. In the senior party patent application,
senior party has illustrated the prior art NEMA Head fixture

prior art is described thusly:
The prior art is illustrated in FIG. 1

an upper bowl-like portion 10 which is
formed from spun aluminum. An upper end of
the bowl-like member 11 receiving a
standard NEMA Head fixture including a
housing 12 which carries a photo control
device 13. An arm illustrated in broken
lines at 14 is received within the
laterally extending hollow bracket 15 in
which it is clampingly engaged by
securement of the bolts 16 and 17. Opposed
fixed clamping members 18 in the form of
latching ears are carried adjacent a lower
edge of the housing 12 for receiving spring
biased clamps, not shown. A lamp is
illustrated at 19 and is received within
the refractor 20 which forms a lower half
of the standard lighting fixture. The
refractor includes prisms which are
designed to direct light downwardly into

considerable glare and considerable light
