Street lighting factors in safety of all

Media Replies 09 May 2019 LED lights

We thank Mr Kevin Lim Kheng Aun (LED lights can make it harder to see pavements, 25 April) and Mr Ramamurthy Mahesh Kumar (Time to tackle light, noise pollution, 25 April) for their feedback on light-emitting diode (LED) street lights. 

The LED street lights that LTA has adopted comply with international standards, such as the European standards (BS EN 13201) and the International Commission on Illumination standards. Safe for road users, their lighting levels are comparable to conventional High Pressure Sodium (HPS) lighting.  They are able to reproduce the colours of objects more accurately and meet international standards on allowable levels of blue light emission.

To manage light pollution, LED street lights used in Singapore provide top-down directional lighting that disperses light rays in a uniform manner. This minimises the scattering of light rays beyond unintended areas and reduces the amount of light infiltrating to surrounding residential estates.

LED street lighting yields many benefits, in particular superior energy efficiency and durability. LTA will continue to monitor the street lighting conditions closely and make further adjustments where necessary.
