1. Expressway
Expressway bears the burden of heavy traffic flow with fast speed from interlinked cities, it has high demand about brightness for a long time at night. So all in one solar street light with small size of solar panel and equipped with motion sensor is not suitable for the case. All in two solar powered street light from DS group is perfectly matching the needs of such case, which can work at high output for long time thanks to its huge space for solar panels and battery.
2. Highway
Highway lighting plays a vital role for ensuring the safety of drivers in the high speed car at night.thus, it serves much broader purpose compared to street lighting in cities. Firstly, its brightness requirement is higher, secondly, its covering area need to be bigger, lastly, it should be free of glare and have uniform lighting performance.
3. Main road in the city
Such roads are usually full of crowded people even at the late night, to avoid car accidents, the lighting on the road should keep working at high power for the whole night,meanwhile, main roads in the city are having limited space for poles installing on two sides, which requests lighting installed to have a wider covering area. For such cases, All in two solar street lights are recommended from Dison group.
