3. The finish (paint) shall withstand minimum 1000 hours salt spray resistance testing per ASTM 6117 (extruded aluminum may be anodized instead of painted). C. LED Package (Light Source) Requirements 1. The LEDs shall be from Cree, Philips Lumileds, Nichia, Osram or equivalent. 2. The LED package shall have been tested for a minimum of 6000 hours per IES LM- 80 -08. 3. The LEDs shall be available with a nominal correlated color temperature (CCT) between 2700K - 4000K. 4. The LEDs shall have a minimum color rendering index (CRI) of 70. 5. The projected L70 lifetime (the point in time at which the LEDs are expected to produce only 70% of their initial lumen output) for the Retrofit shall be a minimum of 70,000 hours. Manufacturer shall supply a calculation pursuant to the Department of Energy TM -21 calculations. Please follow this link to the DOE TM -21 calculator — www eneraystar oov1TM -2l calculator. D. Photometric Requirements 1. The Retrofit shall deliver gross 90 lumens per watt (LPW) minimum at 350 mA drive current. 2. The Retrofit shall have been photometrically tested in a DLC approved fixture per IES LM -79 -08 by and independent laboratory, or an in -house laboratory with NIST NVLAP accreditation. 3. Photometric Specification: a. The Retrofit light engine shall have a minimum total luminous output of 4,700 lumens and a total wattage draw of no more than 75 watts for the 150 W replacement and have a minimum total luminous output of 2500 lumens and a total wattage draw of no more than 35 watts for the 70 W replacement, b. The manufacturer shall provide documentation via a photometric layout that their Retrofit as installed in the decorative luminaire meets the photometric performance requirements for sidewalk lighting as follows: i. Parameters: 80 -ft. pole spacing, single row, 14 -ft. mounting height, 10 -ft. wide sidewalk, 3 -ft. setback. Retrofit light loss factor (LLF) no higher than 0.85. ii. Requirements: The Retrofit shall have a Type V distribution, and shall provide pedestrian walkway lighting consistent with 0.50 fc minimum average horizontal luminance, and an avg /min uniformity ratio of 4.0 or less, per IES RP -08 walkway lighting recommendations. E. Electrical Requirements 1. The driver (power supply) shall have the following characteristics: a. UL recognized component listed for outdoor use b. Minimum power factor 0.90 c. Maximum THD (Total Harmonic Distortion) 20% d. Compliance with FCC Title 47, Part 15 (Class A) 2. The driver shall be available with input voltage ranges from 120 -277 volts. 3. The driver, as operated in the luminaire, must not exceed the driver manufacturer's maximum case temperature limits for a rated life of at least 50,000 hours. 4. The Retrofit shall be protected against surges according to IEEE C62.42 C High (10 kA and W). RFP FOR LED POST TOP RETROFIT STREETLIGHTS & SARTC STRUCTURE LIGHTING Page 125
