Background
SuperLima is
one of the most success- ful chains of Supermarkets in Den- mark that attends
thousands of clients on a daily basis in more than 90 stores, offering the best
selection of national & international brands.
SuperLima is
also a company aware of its environmental responsibility that’s is why the
company in 2009 started an optimization process to reduce the energy
consumption in their stores. They found that the old lighting system was
inefficient and extremely expensive, increasing operating costs and CO2
emissions.
SuperLima has 90 stores spread across Denmark, with many years of experience, the best brands and a serious commitment to the environment.
The
Challenge
SuperLima,
being in an industry where margins are very thin, are always looking for ways
to be more efficient and reduce costs. So the lightning system in such a
business needs to be efficient, clean, and very cost efficient. At the same
time, any change or modification of the lighting system needs to be done
without any interruption in the daily operations and sales.
SuperLima
was looking to save 50% on the costs genera- ted by lighting the stores. On top
of that every detail counts, the color reproduction so products look inviting,
the temperature of the light so the atmosphere make clients feel comfortable
and the light distribution so the products are easily recognizable.
As “hero”
areas and products like fresh produce, in store bakery, wines and spirits are
vital to maintain and impro- ve turnover per area, finding the right solution
was of utmost importance.
The Solution
Switching to
LED technology was a natural solution to achieve the savings needed and the 750
old florescent tubes was changed to 750 HL-T8N-120CM 22W with a color
temperature of 3000 kelvin to maintain the inviting atmosphere of the
Supermarket. The light quality and distribution make this product the ideal
replacement for traditional fluorescent lighting.
The change
was completed with new tubes in the corri- dors, cashiers and storage areas. In
just one week, our technicians and without interrupting the activities at the
stores, had finished the complete installation of LED te- chnology.
By using the same light fixtures the need for construction work or structural changes to the ceilings were avoided.

The Results
Changing 750
traditional T8 florescent tubes to low con- suming Led902 LED tubes and thus
renovating the lightning system generates a yearly saving of 142,834 kWh, a 51%
savings in energy. This means savings of around €24,000 a year per store.
All the Led902
products have a warranty of 5 years, but the technical lifetime of the
equipment is more than 11 years.
One further
advantage of the new installation is the re- duction in air-conditioning, and
food coolers, because LED light produces a lot less heat than conventional
ligh- ting, this maintain fruits and vegetables fresher for lon- ger. The
environment also wins with this positive change because CO2 emissions are
reduced with 65 tons per year.
