Lighting engineers consider options for greater efficiency: Street lighting initiatives aimed at generating savings are gathering momentum and growing in scope through investment in new technology

Savings can be made by reducing any of the factors. Options available to authorities piloting such measures, however, are considerably greater and more complex in detail.
