the models have been made in blender 2.79 and rendered in cycles.

the models polygon and vertices are as follow-

Lantern_A = polygon->2172,vertices->2,252.

Lantern_B = polygon->763,vertices->821.

Street_lamp_A= polygon->1070,vertices->1093.

Street_lamp_B = polygon->374,vertices->416.

Street_lamp_C =polygon->147,vertices->152.

Street_lamp_D= polygon->1460,vertices->1651.(Lantern_C).

Street_lamp_E =polygon->491,Vertices->489.(Lantern_D).

Street_lamp_F = polygon->581,Vertices->610.

Street_lamp_G = polygon->883,Vertices->908.

Street_lamp_H= polygon->1107,Vertices->1003.

 main_file  = polygon->9056,Vertices-> 9399.(this file contain all the mention lamps and lantern in a single scene)

we have test these models in unity.
