1 an automatic latch. The lens and doorframe assembly, when closed, shall exert <br /> 2 pressure against a gasket seat. The lens shall not allow any light output above <br /> I <br /> 3 90 degrees nadir. Gaskets shall be composed of material capable of <br /> 4 withstanding the temperatures involved and shall be securely held in place. <br /> 5 <br /> I <br /> 6 6. The ballast shall be mounted on a separate exterior door, which shall be <br /> 7 hinged to the luminaire and secured in the closed position to the luminaire <br /> 8 housing by means of an automatic type of latch (a combination hex/slot <br /> I <br /> 9 stainless steel screw fastener may supplement the automatic-type latch). <br /> 10 <br /> 11 7. Each luminaire shall be capable of accepting a 150, 200, 250, 310, or 400 watt <br /> I <br /> 12 lamp complete and associated ballast. Lamps shall mount horizontally. <br /> 13 <br /> 14 9-29.10(1)B Light Emitting Diode (LED) Conventional Roadway Luminaires <br /> I 15 LED Conventional Roadway Luminaires are divided into classes based on their <br /> 16 equivalent High Pressure Sodium (HPS) luminaires. Current classes are 200W, 250W, <br /> 17 310W, and 400W. LED luminaires are required to be pre-approved in order to verify <br /> 18 their photometric output. To be considered for pre-approval, LED luminaires must meet <br /> I 19 the requirements of this section. <br /> 20 <br /> 21 LED luminaires shall include a removable access door, with tool-less entry, for access to <br /> I <br /> 22 electronic components and the terminal block. The access door shall be removable, but <br /> 23 include positive retention such that it can hang freely without disconnecting from the <br /> 24 luminaire housing. LED drivers may be mounted either to the interior of the luminaire <br /> I <br /> 25 housing or to the removable door itself. <br /> 26 <br /> 27 LED drivers shall be removable for user replacement. All internal modular components <br /> I <br /> 28 <br /> 29 shall be connected by means of mechanical plug and socket type quick disconnects. <br /> Wire nuts may not be used for any purpose. All external electrical connections to the <br /> 30 luminaire shall be made through the terminal block. <br /> I 31 <br /> 32 LED luminaires shall include a 7-pin NEMA photocell receptacle. The LED driver(s) shall <br /> 33 be dimmable from ten volts to zero volts. LED output shall have a Correlated Color <br /> 34 Temperature (CCT) of 4000K nominal (4000-4300K) and a Color Rendering Index (CRI) <br /> I 35 of 70 or greater. LED output shall be a minimum of 85% at 75,000 hours at 25 degrees <br /> 36 Celsius. <br /> 37 <br /> I <br /> 38 LED luminaires shall be available for 120V, 240V, and 480V supply voltages. Voltages <br /> 39 refer to the supply voltages to the luminaires present in the field. LED power usage shall <br /> 40 not exceed the following maximum values for the applicable wattage class: <br /> I 41 <br /> Class Max.
