COMMONSENSE APPROACH TO ECONOMIES IN LIGHTING

The author explains how false economies can occur by reducing street lighting. Very little cost or energy can be saved by either reducing the number or operating hours of street lights. The small saving is very often counterbalanced by large expenses incurred by an increased number of accidents and crimes. Councils who think that cuts in lighting have made a valuable contribution to energy conservation are mistaken since public lighting accounts for only 0.2 per cent of the total primary energy consumed in Britain. Large economies and better illumination can result from alternative light sources; changing a 200w tungsten lamp to a 35w low pressure sodium lamp can produce a 49 per cent annual cost saving and an extra 65 per cent light output. Examples are given of savings by the Greater Manchester Metropolitan County Council, and Essex County Council who have undertaken light conversion schemes. /TRRL/
