  • Soraa LEDs Illuminate Saalfeld Fairy Grottoes
Jun 2016
FREMONT, Calif., June 3, 2016 — The LED lamps of lighting technology provider Soraa have been installed to illuminate the mineral formations of Saalfeld Fairy Grottoes in Thüringen, Germany.

Through Soraa LEDs and lighting artist Rolf Zavelberg’s approach to lighting design, thousands of visitors can now see the subtleties in the stalagmite colors within the underground caverns.

“Our approach is poetry in light, searching for hidden beauty that can be amplified by light and shadow,” Zavelberg said. “We want visitors to be in awe of nature’s beauty and creative forces in the Saalfeld Fairy Grottoes. There is an artistry in the caves that is only perfectly illuminated with Soraa LEDS. There are thousands of variations in single colors that can be seen now.”

The different color temperatures and optics from Soraa’s LED lamps enabled the caves at Saalfeld Feengrotten to produce a very detailed and sophisticated lighting production that does not alter the character of the grottoes. The caves at Saalfeld Feengrotten are illuminated using Soraa’s Violet-Emission 3-Phosphor (VP3) LED technology. Utilizing every color in the rainbow, the lamps accurately render warm tones, achieving a color-rendering index of 95 and deep red rendering of 95. Unlike blue-based white LEDs without any violet emission, the lamps have violet emissions to properly excite fluorescing brightening agents including paper and natural objects.

Soraa is a provider or LEDs built from pure gallium nitride substrates.
