reference lamp to that of a reference ballast with the same lamp,
expressed as a percentage and used to correct rated luminaire light
output.

D. Coefficient of Utilization (CU): Ratio of incident light as measured
at the workplane to the light output of a luminaire integrated over a
solid viewing angle (usually 180^o^), expressed as a percentage and
highly dependent upon the conditions of the installation.

E. Color Rendering Index (CRI): Inverse ratio of the degree of perceived
chroma shift when an object is illuminated by a test lamp as compared
with illumination by a reference source of the same color temperature,
expressed as a percentage where zero color shift from the reference is a
CRI of 100%.

F. Correlated Color Temperature (CCT): Absolute temperature of a
blackbody whose chromaticity most nearly resembles that of the light

D. Electrical: Ground non-current carrying parts of electrical equipment
in accordance with UL and NEC requirements. This includes bonding the
circuit's green wire to luminaire.

E. Conduit: Conduit shall not be fastened to tee-bar support hangers,
but shall be supported by building steel, Unistrut, or other dedicated
hangers and structural material installed for the specific purpose of
supporting the conduit.

F.  Lamp Installation: New lamps shall be provided for each fluorescent
    fixture installed. Lamps shall be free of dirt, oils, and
    fingerprints.

G.  Fixture Whips: For fixtures such as troffers in lay-in ceilings or
    suspended fixtures whose final location is not known, flexible
    fixture whips shall be used to connect the fixture to the building's
    lighting conduits. For interior installations under NEMA 1
    conditions, type MC cable may be used as a fixture whip. For all
    other conditions under more severe conditions, flexible metal or
    Liquidtight^^ type conduit with separate wiring conductors shall be
    used. When the fixture is fused as specified in paragraph 2.02(D)
    above, the whip's conductor size may be reduced to AWG 16 minimum,
    but not below that required to carry the full load current of the
    fixture.

## 3.02 FIELD QUALITY CONTROL

A. Field Test: Upon completion of installation of lighting fixtures, and
after circuits have been energized, apply power and demonstrate
capability and compliance with requirements. Correct or remove and
replace malfunctioning units, then re-test to demonstrate compliance.
Coordinate field tests with SDR.

B. Acceptance Criteria: Luminaires shall be clean and fully operable at
the conclusion of the work, with no inoperative units. Contractor shall
replace inoperative lamps, fuses, and ballasts at Contractor\'s expense
prior to completion of the work.

C. Preparation and Cleaning: At the conclusion of the work, or when
directed by SDR, remove any protective covering from luminaires. Clean
all dirt, fingerprints and debris from lens, parabolic insert(s),
lamp(s), and lamp and ballast compartments. Insure proper seating of
lamp(s) in sockets. Insure proper and secure engagement of any lens or
cover locking devices. Insure proper alignment and leveling of fixtures
mounted in a tee-bar type ceiling grid.

D. Upon completion of all work, securely affix a round, self-adhesive
label, light green in color and approximately ½ inch in diameter (Avery
#450 or equivalent) to the outside of each fixture. A second label,
identical to the first except yellow in color, shall be placed adjacent
to the first label. The month and year the fixture was placed into
service shall be printed on both label types. The labels will be placed
in the same location for each fixture type occupying a given room or
hallway, and shall be visible and legible from the floor. Labels shall
not be placed on the ceiling surface. These labels are used by Sandia to
quickly determine the age of the lamps and ballasts, respectively, for
the Group Relamping program.
