The government of Thailand plans on replacing legacy light fixtures in Bangkok with
over 400,000 LED streetlights, providing an energy savings of 70%. Forth streetlights
using Lumileds high-power LEDs were chosen for the project due to their high flux,
high efficacy and reliability.
A few years ago, Bangkok installed LED traffic signals throughout the city and realized
the many benefits of LEDs, including long life and a rapid payback period. In 2014, the
Thailand government decided that the high maintenance cost of legacy streetlights
warranted an investigation into LED replacements, provided that its strict specifications
for light quality and reliability could be met.
