Brilliantly illuminating the beauty of the Prambanan Temple Compounds.

Vividly illuminating the Prambanan, a Hindu temple compound that is a World Heritage Site which was built in the 9th-century. It was registered as a World Heritage Site in 1991. The LED illumination project was implemented to attract tourists and to promote the local economy. The color temperature varies in accordance with the time of night giving the temples a unique appearance and brightly illuminating the temple surfaces.

A brighter future with new light

One of the largest Hindu temples in Indonesia,
Prambanan is noted for its distinctive pointed pinnacles.

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 Panasonic developed lighting patterns (silver, platinum, gold, etc.), as well as an approximately 30% reduction in power consumption compared to the existing HID floodlights.

In addition, a more impressive illumination of the site could be realized (better color tones, sharper), and a significant decrease in maintenance work such as replacing lamps.

The route to adoption of LED at World Heritage Sites

Prambanan’s beauty was maximized with three different illumination patterns.

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.
