Mossvet specialists control not only transport arteries, but also parks, sports grounds, courtyards and even apartments of Muscovites.

Every evening in the capital, almost million lamps, and Moscow is rightfully one of the five most illuminated cities in the world. This huge farm is monitored by specialists from the State Unitary Enterprise “Mossvet”… The company carries out technical supervision of all outdoor lighting in Moscow – from road lamps to architectural lighting – and also monitors the state of illumination. To do this, every evening, a mobile lighting laboratory checks the illumination of highways, parks and apartments. How engineers work and how bright Moscow should be, we tell on Mossvet’s birthday.

Road alphabet

The mobile laboratory goes to the evening duty according to the schedule of switching on the outdoor lighting. This time is scheduled down to the minute and changes every day: for example, on July 27, the lights in Moscow are turned on at 21:03, and on August 27 at 19:47 – the full schedule can be viewed at website Mossvet.

One of the main tasks of specialists is to check how well the roads are illuminated, because the safety of both motorists and pedestrians depends on this. Depending on the traffic intensity, each road gets its own classification: A, B and C. The busiest and largest highways are referred to group A, the least loaded – to group C.

Category A includes the Moscow Ring Road and the Third Transport Ring, outbound highways, for example, Leningradskoye and Rublevskoye Highways, as well as the Garden Ring and some central streets. Category B roads include the main streets of regional significance, for example, Shosseynaya and Lyublinskaya. Category B includes such streets and roads of regional significance as 1st Vladimirskaya and 8 Marta Street.

All roads of categories A and B are annually inspected. To check the highways, Mossvet specialists use a “bright meter” – a digital camera that measures the brightness level of the road surface.

It is installed behind the windshield almost like a car DVR and connects to a computer with special software.


The name of the unit of measurement comes from the Latin word candela (“candle”), because one candela is approximately equal to the intensity of the light of one candle.

Moscow suite

Another device that Mossvet engineers use is a light meter, a small box connected by a wire to a photosensitive element. With its help, measurements are taken on playgrounds, in yards, in parks, squares, apartments, in a word, wherever you cannot go by car.

Each object has its own illumination rate. For any playground and playground, this figure should be 10 lux, and in the courtyard itself – four lux. For comparison, a full moon in the tropics equates to an illumination of one lux, and a very cloudy day to 100.

“According to statistics, people most often complain about the darkness, but recently, on the contrary, there have been many applications for excessive brightness,” said Oleg Polovinkin. – For example, because of the new LED lights, because they have a white spectrum light. As a rule, such lamps do not have any violations of the norm, just Muscovites are not used to them. “

Also, residents are often asked to check the illumination of the courtyards. In the overwhelming majority of cases, experts do not detect any violations.

Both to the council and to Facebook

The main roads are checked by Mossvet specialists regardless of the circumstances, and the rest of the objects leave mainly on request. The appeal is selected for work on a regional basis. For example, if the CAO has 10 applications, then the mobile lighting laboratory goes north.

In total, in 2020, Mossvet employees carried out 2,760 inspections: 768 measurements with a lux meter and 1992 with a camera. Despite the fact that a huge territory is under the control of specialists – engineers travel to both the Troitsky and Novomoskovsky administrative areas and Zelenograd – on average they manage to complete four to five applications per shift. The appeal can also be left on the page in the social network – not a single one is left unattended.

“There are many options for how you can apply for a light level test: portal “Our town”, district government, prefecture. They even write to us directly by mail or Facebook. There are 30 days to process a complaint to arrive, measure the violation and submit a report to JSC “OEK”, if something concerns outdoor lighting, or OATI “They control, among other things, violations related to the quality of outdoor lighting,” said the senior engineer.
