Fortimo LED linear light modules deliver

high-quality white light, creating a natural,

welcoming atmosphere in residential areas


Gavoi, a small municipality on the Italian island of Sardinia, is famous

for its pecorino cheese. The historic centre, with its charming

Romanesque San Gavino church, is more than worth a visit. Even so,

time has not stood still here, and the municipality has made reducing

its power consumption and CO2 impact a priority. For example,

the town collaborated with a major supplier of solar power to

equip a large public building with solar panels. And planning to install

LED-based public lighting ensured that municipality received a grant

to replace the outdated luminaires.

The challenge

The existing lighting in Gavoi comprised high-pressure sodium lamps

in two common wattages, 100W and 120W. The main disadvantage

of these lamps is the unnatural yellow light. This light results in poor

colour rendering of illuminated objects, and produces a lot of

spill-over light, creating irritating light pollution and wasting energy.

Opting for the Neri Lanterna PN804L321 has delivered two benefits

for the price of one – improvements in the quality of light and a

dramatic reduction in power consumption. The secret inside these

attractively shaped, classically styled lanterns is the innovative Philips

Fortimo LED linear light modules (LLM). Fortimo LED LLM system

provides high-quality, natural white light that makes people feel safe

and comfortable.

The solution

350 Lanterna luminaires equipped with Fortimo LED LLM were installed

on 40 streets in Gavoi. Initially the municipality had reservations about

switching to LEDs, expecting a harsh bluish light. Once the first lanterns

were installed, it became clear that these doubts were completely

unfounded. The pleasant, warm white light from the Fortimo LED LLM has

excellent colour rendering. This ensures that even at night the village retains

its characteristic appearance and charming atmosphere. And thanks to the

excellent optics in the Lanterna, the light only shines where it is needed.


Both the municipality and the residents are enthusiastic about the new

lighting in their village. The residents especially appreciate the natural

colours and easy recognition of their surroundings in the evening and,

as a result, they feel a great deal safer. The municipality is very pleased

with the tremendous energy savings achieved with this lighting solution.

When compared to the previous high-pressure sodium lamps, with

power usage of 100W to 120W, the Fortimo LED LLM only consumes

53W, delivering a cost reduction of over 50%! The Fortimo LED LLM

has a lifetime of 50,000 hours, compared to approximately 20,000 hours

for high-pressure sodium lamps, which also cuts overall costs and

significantly reduces maintenance expenditure. A good thing indeed,

because with the money that has been saved, the municipality can

invest in other important initiatives to benefit the village residents.
