feel should consider, from the direction of the light distribution of LED street light compared with the traditional metal halide lamp lights have a big advantage, is easy to secondary light distribution. Traditional street lamp cast under the pavement is elliptic spot, a lot of light is projected onto the unnecessary parts, so need more luminous flux of lamps and lanterns can ensure the road illumination. And LED street light after the secondary light distribution can be made rectangle plate, LED street light, so as to adapt to the road.

second, most of metal halide lamp lights the spectrum is red light, red light of visual response is very low, compared with green need more radiant flux can achieve the same luminous flux.

so feel LED street light influence smaller.

the above in view of the urban environment, can afford a filter local tyrants find less light pollution.
