CU Phosco's Lighting Upgrade at Democracy Monument Roundabout Illuminates Bangkok's Historic Landmark with 77% Energy Savings

The Democracy Monument, a historical beacon in Bangkok, has received a
remarkable lighting upgrade to celebrate His Majesty the King's 72nd birthday. This
project, executed in collaboration with Tasjinda Co, Ltd, highlights CU Phosco's
expertise in delivering energy-efficient, high-performance lighting solutions.

The Democracy Monument, located in the heart of Bangkok at the intersection of
Ratchadamnoen Klang Avenue and Dinso Road, symbolises Thailand's transition to
a constitutional monarchy. Built in 1939 during the reign of King Rama VIII, this
historical landmark has now been illuminated to match its grandeur, thanks to CU
Phosco's state-of-the-art solutions. This project, part of the broader "Celebrations on
the Auspicious Occasion of His Majesty the King's 6th Cycle Birthday Anniversary,"
aimed to enhance the visual appeal and safety of the surrounding roads.

CU Phosco, through their local agent Tasjinda Co, Ltd, provided a comprehensive
lighting solution featuring FL800D LED floodlights. These floodlights, known for their
performance, versatility, and reliability, were crucial in achieving the project's
objectives of increased brightness, minimal light pollution, and significant energy
savings.

12 FL800D floodlights replaced the previous 40 metal halide luminaires. They offer
full azimuth rotation and tilt functions, ensuring optimal light distribution tailored to
the monument's unique needs. With built-in drivers and the AeroFlow® Cooling
System, the floodlights provide exceptional thermal management, enhancing their
durability and efficiency. Using Samsung CSP LEDs further ensures high-lumen
output with minimal depreciation over time, maximising energy efficiency and
reducing operational costs.

The FL800D floodlights' superior luminaire efficacy of 156 lm/W and their dark sky-
friendly design with minimal glare ensured compliance with IESNA standards,
minimising light spill into the monument and surrounding areas.

The team further demonstrated their expertise by replacing mast-mounted control
cabinets, connectors, and underground cables within 60-day days, transforming the
historic site's infrastructure.
The successful implementation of CU Phosco's solution resulted in a significant
increase in lux levels and safety at the Democracy Monument Roundabout. The
advanced technology and lighting performance meant fewer fittings were required,

reducing the number of luminaires from 40 to 12. This transition from 440W metal
halide luminaires to FL800D LED floodlights delivered a remarkable 77% energy
savings, contributing to the project's sustainability goals.
The enhanced lighting ensures safe navigation for drivers and pedestrians, with
improved visibility and minimal glare. The new lighting system not only highlights the
monument's architectural beauty but also aligns with Bangkok's commitment to
energy efficiency and environmental sustainability.

"The collaboration with CU Phosco on the Democracy Monument project has been a
testament to the power of innovative lighting solutions in enhancing safety and
sustainability at one of Bangkok's most historic sites. This successful project
underscores our commitment to delivering excellence in every aspect of lighting
design and implementation," said Pop Jindavanich, representative of Tasjinda Co,
Ltd.
