Specifications include, but are not limited to: Sealed bids are invited and will be received by the Telfair County Board of Commissioners for the upgrade to LED Lighting at the Telfair Recreational Complex. The LED Lighting upgrade will be for the following venues: the Baseball Field Wagon Wheel, the Football Field/Track, and the Tennis Courts. B. The fixture shall meet the following specifications: 1. General: a. UL Certified for wet locations. b. Operating temperature range rating between -40°C and +40°C c. Certified to UL 844 and ANSI C136.31, 1.5G vibration requirements. d. IP Rating: IP66 e. Lumen output < 111,000 f. Power consumption < 724W g. Efficacy of ≥137 lumens/watt h. Correlated Color Temperature (CCT) of 5700K i. CRI of ≥ 70 j. L70 lumen depreciation rating: >66,000 hours certified based on IES recommended 6x measured data extrapolation limitation. No extrapolation beyond 6X permitted. k. Weigh ≤ 58lbs, including power supply, bracket, and controls. l. Effective projected area (EPA) ≤ 1.93 ft2 m. Pre-aiming for orientation around the mounting location bolt n. Pre-aiming for tilt on the yoke with locking pin with increments under 1/2o 2. Integrated and Thermally Isolated Power Supply: a. Wide input range of 120VAC to 277VAC or 347VAC to 480VAC b. Power factor: >0.97 @ 277VAC and >0.98 @480VAC c. THD (Total Harmonic Distortion) ≤20% d. Dim to off capability e. Luminaire shall contain four power supplies (drivers) such that if one driver is not operational the other continues to power all the LEDs in the light head. f. Drivers, controls connections and all wiring connections shall be contained in an IP66 enclosure. No exposed connections permitted. No additional junction box permitted. g. Driver case temperature shall be maintained at or below driver manufacturers warranty limits at 40°C ambient in order to preserve long term reliability. 3. Optical system: a. Luminaire shall incorporate silicone TIR plus secondary reflector optics with depth greater than 2.5” to minimize glare perception. b. Fixture shall have a sealed glass cover to minimize dirt depreciation and protect the optics and LEDs. c. No exposed optics or reflective visors permitted. d. No polycarbonate optics due to yellowing and UV degradation. e. No acrylic lenses due to cracking potential. f. LED light source shall be Chip-on-Board (COB) technology. g. No Full Cut off visors, to eliminate the need for uplighting.
