CTA Project No. 19-0035-001-01 16500-5 Golden Shores Street Lighting <br />October 12, 2020 SIB Bid No. 20-09-01 <br />5. The optical assembly of the luminaire shall be protected against dust and <br />moisture intrusion per the requirements of IP -66 (minimum) to protect all optical <br />components. <br />S. Thermal Management <br />1. The thermal management (of the heat generated by the LEDs) shal l be of <br />sufficient capacity to assure proper operation of the luminaire over the expected <br />useful life. <br />2. The LED manufacturer’s maximum thermal pad temperature for the expected life <br />shall not be exceeded. <br />3. Thermal management shall be passive by design. The u se of fans or other <br />mechanical devices shall not be allowed. <br />4. The luminaire shall have a minimum heat sink surface such that LED <br />manufacturer’s maximum junction temperature is not exceeded at maximum <br />rated ambient temperature. <br />5. The heat sink material shall be alumin um. <br />2.03 LED DRIVERS <br />A. Drivers shall have a voltage range of (120 -277) +/- 10 percent at a frequency 60Hz. <br />B. All drivers shall be designed to a power factor >90 percent with a total harmonic <br />distortion THD <20 percent at full load. <br />C. Case temperature shall be rated for -40 degrees C through +80 degrees C. <br />D. Drivers shall have overheat protection, self -limited short circuit protection and overload <br />protected. <br />E. Drivers shall be furnished with a fused primary. <br />F. Drivers shall have an output current ripple <30 pe rcent <br />G. Drivers shall have a five (5)-year (50,000 hour) warranty. <br />H. Drivers shall be manufactured by Advance, Universal or equal. <br />I. Drivers shall be UL Listed for damp location, UL879, UL1012, UL935, ROHS. <br />J. Drivers shall meet FCC 47 Sub Part 15. <br />K. All drivers shall be provided with ANSI/IEEE C62.41 Category C (10kV/5kA) surge <br />protection. <br />2.04 LIGHTING POLES <br />A. Poles shall be designed to withstand calculated wind force based on 1 70 MPH (three <br />(3)-second gust) wind velocity in accordance with the provisions of the Fl orida Building <br />Code without structural damage. <br />B. Pole mounted Luminaires shall be mounted on poles as designated in the Luminaire <br />schedule or as indicated on the drawings. Poles shall have adequate handholes and <br />weatherproof receptacles where indicated. All mounting hardware shall be stainless <br />steel. <br />C. One (1), ¾-inch diameter, 10-foot long, copper-clad steel ground rod shall be driven <br />adjacent to each pole. The pole, steel reinforcement bar in the base, and equipment
