Rural choose how many meters height of led solar street light is very critical, because a lot of rural street with power lines, so consider the height of the led solar street lamps will encounter lines pose a safety hazard. Rule of thumb, 5 ~ 6 meters high led solar street light is suitable for rural situation at the scene. And solar street lamp wattage is determined according to the height of the street lamp light pole, countryside with 5 ~ 6 m solar street lamps equipped with 30 watt LED lamp holder is ok. I emphasize here is the LED lamp wattage is sufficient power, a lot of LED solar street light is power down mode. Led solar street lamps lighting the length can be automatic adjustment, automatic light up at night, and automatically shut down during the day. However the led solar street light can also control the lighting time, rural, generally speaking, 6 hours, eight hours, this will depend on the specific conditions in the village. 5 ~ 6 meters of led solar street lamps spacing in 20 meters to 30 meters, a range of lighting effect is good. At the same time, according to the actual situation of rural appropriate adjustments, but it is worth noting that must let the sun rays to solar panels.
