# PART 2 - PRODUCTS

## 2.01 [GENERAL]{.underline}

A. All material shall be as specified unless noted \"or approved
equal\". Any H.I.D. fixture substituted by the contractor shall not only
be similar in appearance to the specified fixture, but also must have a
coefficent of utilization and candle power distribution within 10
percent of the specified fixture. In addition, the manufacturer shall
submit photometric data to substantiate coefficients of utilization,
candle power curves and zonal lumen efficiency.

B. All units approved shall bear a National Recognized Testing
Laboratory (NRTL) label and be NRTL listed for the application.

C. Ballasts, luminaires, and lamps shall be of commercial grade, unless
specified otherwise on contract drawings.

D. Luminaires for recessed or surface ceiling mounting shall include, in
the shop drawing submittal, complete dimensions, the details of mounting
and hardware, door construction, suspensions and latching, lens
thickness, ballast and lamp location, heat shield if required, and
gauges of steel and finishing process used.

## 2.02 [BALLASTS]{.underline}

A. Ballasts shall be in a separate compartment from the lamps and shall
be encapsulated for quiet operation.

B. Ballasts shall be of the regulator type, except for those wattages
for which regulator types are not manufactured.

1\. The ballast shall also be manufactured to the ANSI C82.4 and ANSI
C82.5 standards and operate the lamp within the limits of the ANSI
voltage-wattage trapazoid.

2\. The ballast shall be designed to accommodate +/- 10% variation in
line voltage and have a power factor of 0.9 or better.

## 2.03 [LUMINAIRES]{.underline}

A. The H.I.D. luminaire shall be a complete, coordinated assembly of
ballast, ballast housing, reflector, diffuser and heat shield as
required, wiring compartment, mounting device and hardware (unless
remote mounted ballast is specified). All components shall be connected
by secure mechanical means to reduce vibration noise and to prevent
detachment of any components due to shock or vibration.

B. Lay-in type Fixtures

1\. Lay-in type fixtures shall have earthquake clips to secure them to
T-bars.

2\. Luminaires weighing less than 56 lbs. shall have, in addition to the
requirements outlined above, two No. 12 gage hangers connected from the
fixture housing to the structure above as a seismic restraint. These
wires may be slack. Luminaires weighing 56 lbs. or more shall be
supported directly from the structure above by approved hangers.

3\. Where plastic lens are specified, the lens shall be 0.4\" thick
acrylic and shall be mounted in the door in such a manner that the lens
cannot fall due to vibration. In addition, the plastic lens shall be
protected by a glass shield in case of violent lamp failure.

4\. The door shall have a positive hinge and latch with a light-leak
gasket.

C. High-bay Type Fixtures

1\. High bay fixtures shall be mounted from cast wiring boxes with
hangers. The fixture mounting device shall be of the compression 3/4\"
conduit type with set screw. Gravity type hanger hubs on fixture are not
acceptable.

2\. Unless specified otherwise, reflectors shall be smooth parabolic of
.064\" aluminum stock finished and sealed in aluminum oxide to a
thickness of 7.5 mg per square inch by an Alzak process (refer to
Standard Drawing Number 94538 - 2 sheets).

## 2.04 [LAMPS]{.underline}

A. High intensity discharge lamps shall be metallic halide or
high-pressure sodium as defined by the IES and as specified on the
construction drawings. Lamps shall be manufactured and listed by the
manufacturer to ANSI C78-1300 series standards.

1\. Lamp bases shall be of the mogul screw type.

2\. Lamp bulbs shall be of the BT, ED, and E shape, of either clear or
diffuse material.

3\. The lamp shall meet all of the requirements of the ANSI C78.380 and
ANSI C78.1300 Series Standards.

4\. The ballast and luminaire in which the lamp is used shall be
approved for the application by the lamp manufacturer.

5\. Metal halide lamps shall be mounted in a vertical axis for maximum
efficiency, unless specified otherwise in the contract drawings.

B. [LAMP STANDARDIZATION]{.underline}

1\. Lamps for facilities illumination, both indoor and outdoor, shall
normally be of standard manufacture, such as manufactured by GE,
Westinghouse, Sylvania, or equal.

2\. If non-standard lamps are used, a stamped or engraved metal tag with
the lamp ordering number shall be permanently attached by mechanical
means, to the luminaire and the Contractor shall identify the lamp by
this ordering number on two shop drawings submittals.

3\. Only those high pressure sodium lamps listed in the High Pressure
Sodium Lamp Table will be acceptable (refer to Standard Drawing 94537).

# PART 3 - EXECUTION

## 3.01 [BALLAST INSTALLATION]{.underline}

A. All ballasts shall be connected to the building ground system.

B. Connect ballast transformer taps, if provided, to maintain ballast
voltage within manufacturers recommended tolerance.

C. Use a receptacle type power connection, if available, as electrical
disconnects for high and low bay fixtures. If not available, use
twist-lock receptacles/plugs with SO cord for the electrical disconnect.

D. Ballasts shall be securely fastened to the luminaire housing for good
thermal contact.
