CTA Project No. 19-0035-001-01 16500-4 Golden Shores Street Lighting <br />October 12, 2020 SIB Bid No. 20-09-01 <br />G. Each luminaire shall be rated for a minimumTM-21 operational life of 60,000 hours at an <br />average operating time of 11.5 hours per night at 40ºC (104ºF). <br />H. Reported lumen maintenance shall be greater than 96% per TM -21-11 after 60,000 <br />hours of luminaire operation in an ambient environment of 40ºC (104ºF). This data must <br />be TM-21 compliant and derived from the EnergyStar.gov TM-21 Calculator. <br />I. The rated operating temperature range shall be -40°C (-40ºF) to +40°C (104ºF). <br />J. Each luminaire is capable of operating above 104°F (40°C), but not expected to comply <br />with photometric requirements at elevated temperatu res. <br />K. Photometry must be compliant with IESNA LM-79. <br />L. Each luminaire shall meet all parameters of this specification throughout the minimum <br />operational life when operated at the average nighttime temperature. <br />M. The individual LEDs shall be constructed such t hat a catastrophic loss or the failure of <br />one LED will not result in the loss of the entire luminaire. <br />N. Luminaire shall be constructed such that LED modules may be replaced or repaired <br />without replacement of whole luminaire. <br />O. Each luminaire shall be damp o r wet lo cations and shall be listed with Underwriters <br />Laboratory, Inc. under UL1598 for luminaires, or an approved equivalent standard from a <br />nationally recognized testing laboratory. <br />P. Surge Suppression: The luminaire on-board circuitry shall include surg e protection <br />devices (SPD) to withstand high repetition noise transients as a result of utility line <br />switching, nearby lightning strikes, and other interference. The SPD protects the <br />luminaire from damage and failure for common and differential mode transient peak <br />currents up to 10 kA (minimum). SPD conforms to UL 1449. SPD performance has <br />been tested per procedures in ANSI/IEEE C62.41-2:2002 category C high exposure and <br />ANSI C136.2 10kV BIL. The SPD shall fail in such a way as the Luminaire will no long er <br />operate . The SPD shall be field replaceable. <br />Q. RF Interference: LED Drivers must meet Class A emission limits referred in Federal <br />Communications Commission (FCC) Title 47, Subpart B, Section 15 regulations <br />concerning the emission of electronic noise. <br />R. Photometric Requirements <br />1. Optical Assemblies: LEDs shall be provided with discreet over optical elements <br />to provide an IESNA Type V distribution. Additional distributions for glare control <br />shall be utilized when direct source must be mitigated. Mitigation must take place <br />without external shielding elements. Optical assemblies shall have a minimum <br />efficiency of 85% regardless of distribution type. All LEDs and optical assemblies <br />shall be mounted parallel to the ground. All LEDs shall provide the same optical <br />pattern such that catastrophic failures of individual LEDs will not constitute a loss <br />in the distribution pattern. <br />2. No more than 1.8% of the total luminaire lumens shall be in the 80º to 90º range <br />and no lumens will be emitted above 90º. BUG rating shall no t exceed B4-U0- <br />G4. <br />3. Light Color/Quality: The luminaire shall have a correlated color temperature <br />(CCT) of 4,000K +/-275K. The color rendition index (CRI) shall be a nominal 70. <br />4. 54% of the total luminaire lumens shall be to the street side of the luminaire .
