Application Mounting Height Minimum Maintained Light Pattern Figure Illuminance ft fc isofootcandle curve Roadway 1 34 0.15 Pattern defined by an ellipse with the equation: x 2 + (y —20)2 _ 1 �82�z �52�z where: x=direction longitudinal to the roadway y=direction transverse to the roadway and the luminaire is offset from the center of the pattern by 20 feet to the house side of the attern. Roadway 2 40 0.2 Pattern defined by an ellipse with the equation: xZ + (y —20)2 _ 1 (82)2 (52)z where: x=direction longitudinal to the roadway y=direction transverse to the roadway and the luminaire is offset from the center of the pattern by 20 feet to the house side of the attern. Roadway 3 40 02 Pattern defined by an ellipse with the equation: x 2 + (y —23)Z =1 (92)2 (55)2 for y>_0(street side) where: x=direction longitudinal to the roadway y=direction transverse to the roadway and the luminaire is offset from the center of the pattern by 23 feet to the house side of the attern. Roadway 4 40 0.2 Pattern defiried by an ellipse with the equation: xZ + (y —23)2 =1 (92)2 (55)z where: x=direction longitudinal to the roadway y=direction transverse to the roadway and the luminaire is offset from the center of the pattern by 23 feet to the house side of the attern. The luminaire must have a correlated color temperature range from 3,500 to 6,500 K. The color rendering index must be 65 or greater. The luminaire must not allow more than: 1. 10 percent of the rated lumens to project above 80 degrees from vertical 2. 2.5 percent of the rated lumens to project above 90 degrees from vertical Thermal Management The passive thermal management of the heat generated by the LEDs must have enough capacity to ensure proper operation of the luminaire over the minimum operation life. The LED maximum junction temperature for the minimum operation life must not exceed 221 °F. The junction-to-ambient thermal resistance must be 95 °F per watt or less. The use of fans or other mechanical devices is not allowed. The heat sink material must be aluminum or other material of equal or lower thermal resistance. The luminaire must contain circuitry that automatically reduces the power to the LEDs to a level that ensures the maximum junction temperature is not exceeded when the ambient outside air temperature is 100 °F or greater.
