Street lighting: 8 frequently asked questions

Many unpleasant things happen during the darkest hours of the day, such as traffic accidents, theft, etc., and street lighting plays a very important role in these situations. Properly chosen street lighting helps to ensure the safety of residential neighbourhoods and gives an attractive aesthetic appearance to a given space. However, there are often a number of issues that arise when it comes to selecting the most appropriate street lighting for a particular location. We answer the 8 most frequently asked questions about street lighting.

1. Street lighting: what is important to consider when choosing?

The choice of street lighting should take into account several important criteria. First of all, we recommend assessing the luminous efficacy of street luminaires, which is calculated in lumens (lm). It’s good to know that the more lumens a street luminaire has, the brighter the street lighting will be.

Street lighting solutions should also be chosen with environmental considerations in mind, i.e. y choose LED street lights, which save energy, rather than, for example, low-energy sodium and metal halide lamps. Ltd ,,SID apšvietimas”, which has been specialising in lighting solutions for more than 10 years and has illuminated a number of Lithuanian city centres and old towns, proposes to its clients to consider the need of upgrading the municipality’s luminaires for the streets, parks and squares, which are equipped with unsustainable sodium-vapour-vapour-vapour and metal-halide lamps, to energy-efficient and modern LED luminaires with LED modules. LED modules are installed in existing luminaires according to the requirements of each street luminaire retrofit and the light engineering calculations of the street lighting, replacing low-energy lamps. The LED module can be replaced very quickly and the retrofit can be carried out by the operator of the street lighting network as a simple, routine repair of the luminaire.

When choosing street lighting solutions, also pay attention to the design of the street lights. With a wide range of products available from different street luminaire manufacturers, there is plenty to choose from. UAB “SID apšvietimas” assortment includes luminaires of exceptional shapes, unique design in modern and classical styles, designed for functional lighting of modern city spaces and streets.

Several other aspects are also important for the selection of a street luminaire: wattage (W), optics, luminous flux (lm), ambient illumination, and the availability of backlighting. It is worth consulting our experts in each case to find out which street luminaire parameter you should focus on in your choice.

2. What is meant by “efficient street lighting”?

Simply put, energy-efficient street lighting is lighting that uses energy efficiently Such street lighting is equipped with modern technology and state-of-the-art solutions, such as replacing old street lights with advanced and energy-saving light-emitting diode (LED) luminaires. Economical street lighting is also provided in accordance with the prescribed standards (EN 13201) and in line with the category and traffic conditions.

3. Which street lights are considered energy efficient?

Energy saving street luminaires are those street luminaires which have a high luminous efficacy (lm/W). This means that the higher the comparative efficiency (lm/W), the higher the luminous flux generated by 1 W streetlights.

Economical street luminaires are also considered to be street luminaires that have a long service life of at least 100 000 h (about 20 years).
