The same thickness of light why prices vary considerably in 12 meters?

The same thickness of light why prices vary considerably in 12 meters? Both distribution and installation of pole lamp will find, in the same steel price level in a timely manner, the same height and configuration of the pole lamp, price difference is bigger, often spreads more, can reach several hundred yuan price difference, what reason is this? If we will all parameters of the light pole as the same, in the light of the price differences are usually appear on the lamp panel. Appear on the lamp panel for such a big price difference, is mainly affected by the type and quantity of lamps and lanterns, configuration mode. 1, the more the number of the number of lamps and lanterns of lamps and lanterns, the bigger the lamp panel requires, though the light we see on the ground plate size difference is not very big, but the actual production of the size difference and weight of the gap is very big, can differ to a few kilograms. 2, lamps and lanterns of the weight of the difference lamp plate quality, not only has something to do with the number difference of lamps and lanterns, but also related to the weight of the lamps and lanterns, lamps and lanterns is if it is heavier, lamp plate steel also needs more solid and increasing size, especially the LED lamps and lanterns, weight is very big, a lamps and lanterns can often achieve 10 kg, 20 kg, so the strength of the support is very important. 3, arrangement of lamps and lanterns of lamps and lanterns of different irradiation exposure in one direction and in a different direction is different, lamps and lanterns is a configuration and two layer configuration needed materials are also different, so, even as the number and weight of the lamps and lanterns, arranged in different ways, the lamp panel materials will not be the same.
