The Use of LED Lighting on Malaysian Highways: Review on Key Benefits, Challenges, and Environmental Impacts

Abstract

One of the most important components of Malaysia's ambitions for sustainable infrastructure is the installation of Light Emitting Diode (LED) lighting on the nation's roadways. Modern lighting technology is a desirable option for road lighting since it provides a number of benefits. Significant benefits come with LED lighting on Malaysian roadways, including reduced power usage of up to 50%, improved safety and visibility, longer lifespan and cheaper maintenance costs, and environmental benefits (no mercury or greenhouse gas emissions). There are, however, additional difficulties to consider, like the tropical heat of Malaysia's maintenance and dependability issues, local conditions like monkey damage adaptation, and certification requirements. The usage of LED lighting on Malaysian highways can have both beneficial and bad effects on the environment. LED lights are recognized to reduce energy consumption and light pollution, but because some of them have a spectral composition that can cause skyglow, they may also have unexpected effects on animals. It is essential to use LED lighting with the right colour temperatures and optics to reduce these environmental issues. The widespread adoption of LED lighting on Malaysian highways has produced a number of benefits, including improved road safety, lower costs, and higher energy efficiency, making it an essential part of the nation's sustainable infrastructure development.
