This level of detail may be useful to the Contractor, Government, building occupants, or the public in assessing the sustainability of these products. NOTE: This is optional for Army projects. [Submit Table 1 of ASTM E 2129 for the following products: [_____].] PART 2 PRODUCTS 2.1 _{FLUORESCENT LIGHTING FIXTURES} NOTE: For projects within the United States and its possessions, do not specify hard metric recessed lighting fixtures as the only option. UL 1598. Fluorescent fixtures shall have electronic ballasts [unless specifically indicated otherwise]. 2.1.1 Fluorescent Lamp Electronic Ballasts NOTE: Electronic ballasts may have system compatibility problems when installed in certain environments. The problems mainly concern the radiated and conducted EMI due to the relatively high switching frequencies inherent in electronic ballasts and possibly due to utilization of the same power source for lighting and other equipment. Shielding technologies today can prevent interference with surroundings, and therefore this is rarely an issue. Environments where electronic ballasts have the potential for EMI are: 1. Libraries or other facilities which utilize magnetic detectors to prevent theft or inventory control. However, it has been reported that electronic ballasts have no impact on the magnetic detectors if the separation distance is greater than 3050 to 4575 mm 10 to 15 feet. This includes distances in all directions through floors, ceilings, and walls. 2. Facilities using high frequency power line carrier (PLC) control systems, such as a central clock system. These PLC systems usually have a 50,000 Hz to 200 kHz carrier frequency which may be affected by the harmonics generated by the electronic ballasts. 3. Areas where sensitive electronic equipment is installed such as hospital critical care units, other areas utilizing sensitive electronic equipment based life support systems, and electronic testing facilities. With proper design considerations, electronic ballasts should provide satisfactory performance even in these and other sensitive areas. The designer must consider fixture location, fixture performance characteristics, manufacturers' recommendations, environmental constraints, etc. in the lighting design. Edit this specification as required to solve specific design problems. The electronic ballast shall as a minimum meet the following characteristics: a. Ballast shall comply with UL 935, NEMA C82.11, NFPA 70, and CEC Title 24 unless specified otherwise. Ballast shall be 100% electronic high frequency type with no magnetic core and coil components. Ballast shall provide transient immunity as recommended by IEEE C62.41.1 and IEEE C62.41.2. Ballast shall be designed for the wattage of the lamps used in the indicated application. Ballasts shall be designed to operate on the voltage system to which they are connected. b. Power factor shall be 0.95 (minimum). c. Ballast shall operate at a frequency of 20,000 Hertz (minimum). Ballast shall be compatible with and not cause interference with the operation of occupancy sensors or other infrared control systems. Provide ballasts operating at or above 40,000 Hertz where available. d. Ballast shall have light regulation of plus or minus 10 percent lumen output with a plus or minus 10 percent input voltage regulation. Ballast shall have 10 percent flicker (maximum) using any compatible lamp. e. Ballast factor shall be between 0.85 (minimum) and 1.00 (maximum). Current crest factor shall be 1.7 (maximum). f. Ballast shall be UL listed Class P with a sound rating of "A." g. Ballast shall have circuit diagrams and lamp connections displayed on the ballast. NOTE: Choose the bracketed option and require programmed start ballasts for Army and Air Force projects. For Navy projects, provide instant start ballasts for areas not subject to frequent switching (i.e., more than once every three hours). Provide programmed start ballasts for areas subject to frequent switching, including all areas controlled by occupancy sensors. Identify fixtures requiring each type on the drawings. h. [Ballasts shall be instant start unless otherwise indicated. Ballasts shall be programmed start where indicated. Instant start ballasts shall operate lamps in a parallel circuit configuration that permits the operation of remaining lamps if one or more lamps fail or are removed. ][Ballasts shall be programmed start unless otherwise indicated. ]Programmed start ballasts may operate lamps in a series circuit configuration. Provide series/parallel wiring for programmed start ballasts where available. i. Ballasts for compact fluorescent fixtures shall be programmed start. j. Ballasts for T-5 and smaller lamps shall have end-of-life protection circuits as required by NEMA C78.81 and NEMA C78.901 as applicable. NOTE: A source of light other than fluorescent is recommended for areas subject to temperatures below -17 degrees C, 0 degrees F. k. Ballast shall be capable of starting and maintaining operation at a minimum of -17 degrees C 0 degrees F unless otherwise indicated. l. Electronic ballast shall have a full replacement warranty of 5 years from date of manufacture as specified in paragraph entitled "Electronic Ballast Warranty" herein. 2.1.1.1 T-8 Lamp Ballast NOTE: Total harmonic distortion of 20 percent is acceptable for most applications. a.
