LED Flood Light
A brighter future with new light
The Prambanan Temple Compounds were previously lit with HID (high-intensity discharge) lamps, but with rising electricity costs, there was a need to transition to more energy-efficient lighting. It was also expected that new, improved lighting would heighten the appeal of Prambanan, boosting tourism and contributing to the economic wellbeing of area residents.
HID lamps converted to LED
Panasonic proposed the introduction of LED as a replacement. Among its advantages are the ability to select from multiple lighting patterns (termed “silver,?“platinum,?“gold,?etc.), as well as an approximately 30% reduction in power consumption compared to the existing HID floodlights, more impressive illumination of the site (better color tones, sharper shadows on the reliefs), and a significant decrease in maintenance work such as replacing lamps.
The route to adoption of LED at World Heritage Sites
The process of introducing LEDs entailed major obstacles in terms of preservation. As it is not possible to intervene in the sites?surrounding environments, LED floodlights had to be mounted on the bases for existing light fixtures, and existing wiring had to be used as well.
Achieving optimum illumination under these restricted conditions was a task similar to solving a puzzle.
Panasonic performed repeated early-stage simulations and on-site demonstration experiments, completing floodlight angle adjustments and determining lighting pattern settings before delivering the LED units to the site.
High hopes for LED light to boost tourism
We spoke with Mr. Krishna of the site maintenance company about the newly installed LED lighting.
“LED lighting renders the delicate details of the compound’s reliefs beautifully, heightening the exotic atmosphere and making an enduring impact on visitors.
We’re very pleased because it consumes significantly less power than the previous lighting, there is less maintenance work, and the mood can be adjusted according to the situation. For example, it’s easy to select silver at dinnertime, and platinum or gold for Ramayana performances or special events.
We look forward to having more tourists enjoy the beautiful sight of this splendid temple,?says Mr. Krishna, expressing his high expectations for Panasonic LED.
