From July, the Land Transport Authority (LTA) will progressively replace street lights at about 500 roads island-wide with more energy efficient Light Emitting Diodes (LED) lighting.
2. The LED street lighting replacement programme will mainly cover lower-trafficked roads and residential roads, where the street lights have lower wattage (70 to 150 watts) and are reaching product end-of-life. The programme follows a three-year trial conducted along Northumberland Road and Tekka Lane, where 17 lamp posts were fitted with LED lights.
3. With the new LED street lighting, LTA is looking at energy savings of up to 30% compared with the current high-pressure sodium vapour (HPSV) lamps, while meeting the required lighting standards.
4. Approximately 4,000 LED street lights will be installed under this programme. Works will start July 2014 and will complete by Q2 2018.
5. Besides lower-trafficked roads and residential roads, LTA is also actively looking into the possibility of using LED technology for higher wattage lighting >250W along major arterial roads and expressways. LTA is trying out high wattage LED lamps along Lorong 1 Toa Payoh to study energy consumption, durability and maintenance challenges. This trial, which started in August 2013, is expected to complete by 2016.
