Solar LED Path Lighting Pole with 220 Watts of Solar Panel
The lighting had to be designed to illuminate a path area of 18ft x 60ft at an angle of 35 degrees 5 feet away and 10 feet high totaling 32 units.
LED lighting to illuminate 5 foot candles in the center, from the center to 30 ft diameter it had to illuminate 1.25 ft candles and from the center to 60 ft diameter illuminate .25 ft candles. APMFG exceeded the foot candle illumination.
The illumination sequence was most difficult Operating times were as follows: On From 5:00 PM to 11:00PM at 11:00PM the LED's are dimmed to 50% then at 5:00AM back on to100% until 7:00 AM.
