Porirua's future looks bright after switching to 4650 LED lights

The future is looking bright in Porirua (New Zealand) as its old yellow streetlights are being replaced with new white light-emitting  LEDs. Papakowhai and Titahi Bay residents will be the first to see the yellow sodium vapour streetlights go. The rest of the city will be switched over by June. The conversion of 4650 lights around the city - not including lights in parks, sporting facilities and carparks - will cost the council $2.9 million, but it will share that cost with the New Zealand Transport Agency  which will provide all but $357,000.
