INTRODUCTION
The need for solutions that provide energy
savings in full compliance with lighting level
regulations is increasing.
Traditional lighting installations that use High
Pressure Sodium (HPS) are costly to maintain,
energy intensive and often fail to comply with anti
light pollution regulations.
The high colour rendering of the new LED units imitate daylight thereby deterring crime and reducing the fear of crime.

Comparison
ENERGY SAVINGS
Total absorbed power is now 17.7 KW
against 32 KW of the previous
installation.
The overall energy saving is 45% with a
saving of more than 27.4 T CO2e.
(Tons of CO2 equivalent) emitted into the
atmosphere yearly.
ECONOMIC SAVINGS
The economic savings obtained are the sum of energy savings and maintenance
savings over the 10 year life of the new LED fittings.
