6.J. - Page 33 of 108 <br />i. Clarify whether discrepancy does not affect performance, e.g., in the <br />case of differing luminaire housing color <br />ii. If nominal performance of submitted and tested products differ, <br />submit additional LM -79 report(s) and derivation as indicated in <br />Appendix C <br />Description of luminaire, LED light source(s), and LED driver(s) <br />6. Goniophotometry <br />C. Computer-generated paint -by -paint photometric analysis of maintained photopic light <br />levels as per layout parameters and specs called out in Lighting Design Criteria <br />8.0 LIGHTING DESIGN CRITERIA FOR EACH LUMINAIRE TYPE DEFINED IN APPENDIX A <br />Photometric calculations shall be performed using luminaires for 3,000K color temperatures for each fixture <br />type in Appendix A. The photometric calculations/measurement points shall be in conformance with IES RP -9 <br />and shall .be calculated using Visual Lighting software's "Roadway Tool". A PDF file of the "Roadway Tool's" <br />photometric analysis for each fixture.tYpe and a.cop_-Y of the aes file used the photometric calculations for <br />p far <br />each fixture type must be submitted via a USB memor tick. Submitters must use the roadway lighting criteria <br />defined for each fixture type in Appendix A when calculating lighting photometry, The minimum calculated <br />values for average luminance, luminance uniformity ratios (average/minimum, maximum/minimum) and Veiling <br />Luminance Ratio (Lv Ratio) and the minimum calculated values for average illuminance, the illuminance <br />uniformity ratios (average/minimum, maximum/minimum) for each fixture type are defined below in Appendix <br />A. <br />PUBLIC WORKS SERVICES DEPARTMENT <br />FY 2018-19 LED STREET LIGHT FIXTURES NIB 17 OF 36 <br />233 <br />
