baked white enamel. Louvers are low iridescent
semi-specular (diffuse) natural anodized (LD)
aluminum as standard.

An adapter plate is furnished with each luminaire
for fast wiring connections without the necessity of
opening the fixture or wireway. A mylar dust cover
which eliminates construction dust contamination
is standard. Single circuit Tandem wiring is standard
for continuous row fixtures. All shielding and
hangers ship separately.

NP is designed to fit into lay-in (Type G) grid ceilings
or concealed suspension (Type F) ceilings requiring
an overlapping flange. It is also available in an endsupport (Type GT) model which carries the ceiling
tile on fixture side tees (see NP-Narrow Parabolic
Technical Installation Data). Fixture in exposed
grid ceilings (Type G) will have row interrupting
cross-tees on 4' centers. For uninterrupted shielding
without cross tee use end-of-row and intermediate
fixtures.
