Light Sources:
A.
Avoid the use of incandescent light sources for general
illumination except in pipe basements, small closets,
lobbies, and special requirement areas. Compact
fluorescent lamps may be used in lieu of incandescent
where appropriate.
B.
Use fluorescent lamps as the principal interior lighting
source.
C. Utilize high intensity discharge (HID) sources for large
interior utility spaces having relatively high ceilings or
where maintenance is difficult (i.e. mechanical
equipment rooms.) High pressure sodium is
preferable where color is not an important factor.
D. Utilize F32T8 (32 watts only) rapid start, fluorescent
lamps with a color temperature of 3500 degrees K, a
color rendering index (CIE) not less than 69 and an
initial lumen output of 3050 minimum.
8.7
A.
fluorescent lighting that utilizes type F32T8 lamps.
B.
All other fluorescent lamp types shall utilize the
standard energy saving electromagnetic core-and-coil
type.
8.8
Fixtures:
A.
Specify fixtures having high efficiency (output/bare
lamp lumens) where practicable within the visual
constraints dictated by the application.
B.
Specify fixture types which utilize controlling elements
(lenses, louvers, reflectors, etc.) designed to provide
the best utilization of emitted light at the task location.
Use parabolic louver equipped fixtures in office areas,
and similar spaces where CRT equipment is generally
used.
C. In addition to two-lamp and four-lamp fluorescent
fixtures, utilize three-lamp fixtures as required to tailor
the lighting design closer to the required illumination
levels.
