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.
