The document summarizes a student research project on light pollution in Kaunas, Lithuania. The students analyzed lighting systems in the city center and Dainava district, finding that: (1) The city center lighting is now modern and ecological, especially on main streets and in the old town, while (2) Dainava district parks have the worst lighting with old, round bulbs that cause major light pollution and endanger birds/insects. The students recommend paying more attention to lighting design around towns to lower pollution and raising public awareness of this issue.

6. Light pollution in Dainava district
•For example, lights
around Taikos, Studentų
streets are pretty poor
and really old, they were
probably not changed
for many years, the
lights there are really
weak and don‘t spread a
lot of light.

7. Light pollution in Dainava district
• On the other hand, the majority streets in
Dainava have got excellent enlightenment
system, the lights are updated and don‘t
damage the environment that much as the
old ones.

8. Light pollution in Dainava district
Bad examples
•What surprises the most, it is an enlightenment in
parks of our neighbourghood.The green areas
have the worst and the most pollutening
illumination system, which cause the biggest light
pollution – the round light bulbs.

9. The majority of infrastructure in Dainava parks and green
areas are renewed by using EU funding. But the
enlightenment has still stayed the same. Old lights or
round bulbs cause the biggest light pollution and
damages the environment.

10. Light pollution in Dainava district:
conclusions
1. The main problem in our own
Dainavos district is the
enlightenment in the parks and
green areas:
• the most popular are the round
light bulbs, that cause the
biggest light pollution;
• moreover, they cause the danger
for birds and insects.

11. Light pollution in Dainava district:
conclusions
2. In addition, our
municipality doesn‘t
have enough money to
improve all the
illumination, make it
more effective and not
so unhealthy and
polluting.

13. • Before the start of the major modernization,
Kaunas street lighting system was morally and
physically obsolete.
• City center lights had a particularly strong
impact on traffic and safety of residents in the
dark.

14. •Situation is different now.
Enlightenment system in
Kaunas city centre is renewed
and equipped with modern
lamps, which save energy, are
ecological and do not cause
light pollution.
• The best example of
environmental enlightenment
is the heart of Kaunas –
Laisves Avenue.

15. Kaunas old town lighting
• Kaunas old town lighting is
just as good and high-level
as Liberty avenue.
• To increase the security of
the population and to
reduce the light pollution,
streets are equipped with
new, modern lamps, which
provides all the light in dark
streets.

16. In order not to cause light pollution, and
to save the space, lamps are fitted to the
wall of the buildings.

18. Conclusions
Enlightenment system
in Kaunas city,
especially in main
streets and old town
centre is modern,
ecological and
installed according the
all requirements.

19. Recommendations
• The advice, for institutions responsible for
enlightenment, would be to pay more attention to
the enlightenment schemes and design around the
town, in order to lower the light pollution.
• Individual residents, should pay more attention not
only to a design of outdoor enlightenment, but to
the ecology as well.
• The idea of light pollution is a very new and we are
taking the first steps to cope with the problem.With
this research we wanted to raise public awareness to
the damage caused by light pollution and show
some examples of bad lightening in our streets.
