Public lighting is used to provide light to public surfaces. It consists of a lamp, a supportive post and wiring connecting it to a power source. In accordance to rules and regulations, as well as considering the power savings and environmental sustainability, a number of strategies will be presented to integrate the best possible technology on the market, resulting in an energy efficiency norm which can be divided into the efficiency of each individual lamp and the entire public lighting system. This is also an introduction to norm 13201-5. Furthermore, energy ratings will be shown ranked by efficiency of the public lighting system as well as individual lamps. To ensure performance and achieve maximum energy saving, the public lighting system needs to be regularly maintained. Special maintenance equipment is required for all the possible malfunctions that may arise. One of the problems is the fact that the company which offers the lowest price for their work will get the job, which usually results in sub-par quality of work significantly lowering the criteria. Other companies with higher standards are then reduced to lowering their prices in order to stay in demand. The costs of equipment and needed maintenance work on public lighting are too high considering the paid rates brought down by competition. Another present problem, which significantly affects the demands of the norm, is the reduced level of brightness due to the wearing down of the lamp as well as various other components. In order to improve that, the replacement of existing lamps with different lamps of greater efficiency is suggested.
