PART 2 - PRODUCTS
2.1 MANUFACTURERS
A. Manufacturers: Unless otherwise directed by the Owner, provide products by one of the following:
1. Lithonia:
2. Orion Energy:
3. Preston Lighting:
4. Owner Approved Equal
2.2 GENERAL
A. The fixture shall be capable of providing illumination in an exterior open walkway ceiling environment. The fixture shall use fluorescent technology with an optical efficient reflector system capable of providing ³92% Lamp Efficiency between 0° F and 90° F, as illustrated on the lumen summary of the IES Report.
B. The fixture shall be UL Canada approved and listed and tested, shall be electronically tested via 1200-volt HI POT test performed by the manufacturer.
2.3 FIXTURE CONSTRUCTION
A. The ballast and reflector system shall be constructed to thermally isolate the reflector and lamp system from the ballast chamber so as not to cause any decrease in lumen output or lamp life due to thermal deterioration.
B. Fixture Body and Frame: The fixture body and frame shall be constructed in a manner so as to provide maximum heat transfer from ballast and lamps to the surrounding air. The ballast compartment shall be separately enclosed from the main fixture body containing the lamps. A separation shall be provided between the bottom of the ballast compartment and the fixture containing lamps.
1. The maximum case temperature of the ballast shall not exceed 70°C under any condition.
C. Reflector System:
1. The reflector system shall be manufactured with a combined full radius and angled surface. The reflector surface shall not have any facets. The reflector shall be designed to minimize reflecting light back through the lamp, thereby maximizing the fixture efficiency.
2. The reflector material shall be static free to minimize the adhesion of the airborne dirt and dust particles, and shall be easily cleanable with a damp cloth.
3. The reflector shall be continuous and run the full length of the fixture for the entire length of the lamp’s luminous surface.
D. Fixture Mounting Hardware: Fixture hanging cable(s) shall originate from the four outer most corners of the fixture to provide maximum stability and safety. Cables may be hung via a two point or single point system mounted to the roof structure system.
E. Lamp Holders: lamp holders shall be rotary lock style to avoid loose connection and shall be constructed with materials that do not deteriorate when cooling chemical or lubricants are circulated in the air.
2.4 LAMPS
A. Lamps shall be 32-Watt, T-8 with a minimum 80 CRI at 5,000°K, provide 3000 initial lumens (not inclusive of the Ballast Factor), and shall have a rated life of ³24,000 hours per manufacturer’s specification.
1. Lamp temperature shall not exceed 115°F when operating in a 70°F ambient environment.
2. Lamp shall be linear and have nominal length of 48” utilizing standard bi-pin sockets.
3. The fixture manufacturer shall guarantee lamp and ballast compatibility.
B. Provide lamp protection, each individual lamp shall be covered with a full enclosure or a protective covering.
2.5 BALLASTS
A. Ballasts shall be multi-tap high frequency electronic instant start type. Ballast shall be UL Listed, Class P, sound rated A, with THD of 20% or less.
1. Operating Voltage: 208,277 and120V.
2. Minimum Starting Temperature: Minus 0° F for single lamp ballasts.
3. Ballast Factor Rating: 1.15 or greater.
4. Open-circuit operation that will not reduce average life.
2.6 PHOTOMETRY
A. The following percentage of lamp lumens shall be achieved in each of the following zones of lumen distribution.
Zone: %Lamp Lumens % Fixture Lumens
0-30° 33% (less 3%) 35%
0-40° 55% (less 3%) 55%
0-60° 82% (less 3%) 88%
0-90° 92% (less 3%) 100%
Note: No less than a 3% negative variation will be accepted. Positive variation will not be discriminated.
2.7 SPECIAL APPLICATIONS
A. Unheated area where the ambient temperatures may fall below 40°F, the lamps shall be enclosed by a lens constructed of 3/16” thick stabilized, clear virgin acrylic to prevent air from blowing across the surface of the lamps, thereby reducing the lumen output of the lamps.
1. The lamp compartment shall be thermally insulated from the fixture body to maintain the minimum operating temperatures published by the lamp manufacturer.
2. Fixture lamp efficiency shall be ³74% between 0° F and 90° F for enclosed style fixtures.
PART 3 - EXECUTION
3.1 INSTALLATION
A. Fixtures: Set level, plumb, and square with ceiling and walls, and secure according to manufacturer's written instructions and approved submittal materials. Install lamps in each fixture.
B. Fixture Support: Mount on structure as per existing.
3.2 FIELD QUALITY CONTROL (By Installing Contractor)
A. Inspect each installed fixture for damage. Replace damaged fixtures and components.
B. Tests: As follows:
1. Verify normal operation of each fixture after installation.
2. Emergency Lighting: Interrupt electrical supply to demonstrate proper operation.
C. Malfunctioning Fixtures and Components: Replace or repair, then retest. Repeat procedure until units operate properly.
3.3 CLEANING AND ADJUSTING (By Installing Contractor)
A. Clean fixtures internally and externally after installation. Use methods and materials recommended by manufacturer.
