Technical upgrades to public lighting(CLASSIC) reduce energy use (and therefore cost), which can offset the cost of installation and maintenance of new equipment. It depends on the starting price of energy: in markets where energy is highly subsidized, the same benefits may not apply.
Even in developed countries, many public lights in the world are generations. This means that the potential for energy savings improvement is enormous. For example, in Europe, approximately 32% of public lighting is still the standard of the 1930s.
Higher technologies, such as high-pressure mercury or metal halide bulbs, do not match LEDs and other more advanced options. In old technology incandescent bulbs, 90% of the energy consumed generates heat, and only 10% is illuminated. In contrast to conventional 100-watt incandescent bulbs, which produce about 17 lumens per watt of visible light, compact fluorescent bulbs produce 60 to 75 lumens per watt, and LED bulbs exceed 100 lumens per watt. LEDs also have a long lifetime and are three to five times longer than traditional lighting technology.
Due to the accumulation of most of the costs associated with public lighting during operation, the longer the expected service life means the higher the upfront cost of the LED and the shorter the life, the higher the cost of the compact fluorescent lamp.
The intelligent control system can create additional savings because the level of illumination can be adjusted according to the time of day and other requirements, as opposed to traditional systems that only allow the lights to be turned on or off.
