Seoul Semiconductor’s SunLike Series natural-spectrum LEDs adopted by WALTRON for aquarium lighting

South Korean LED maker Seoul Semiconductor Co Ltd says that its SunLike Series natural-spectrum LEDs have been adopted by WALTRON of Lower Saxony, Germany (specialists in LED lighting systems for aquariums and terrariums) for its daytime Pendix aquarium lighting solutions.

Indoor aquariums are full of colorful corals, fish, and water plants living in an ecosystem similar to nature. Direct sunlight is typically avoided in these spaces in order to limit the reproduction of algae and keep water from becoming turbid and harming the ecological balance of the aquarium system. Lighting solutions hence play an important role in maintaining growth without disturbing the ecological cycle.

The daytime Pendix is a matrix LED module with nine different color temperatures and features a customized spectral lighting design that closely matches the spectrum of natural sunlight enabled by SunLike Series LEDs. Different light colors such as white, blue and red can be combined in the module to provide the optimal lighting solution for both saltwater aquariums and freshwater aquariums.

Seoul Semiconductor says that SunLike Series natural spectrum LEDs are similar to sunlight, radiating a uniform amount of energy at all wavelengths, including infrared and ultraviolet as the optimal light source for plant growth. The technology lowers the light peaks of red, green and blue to be more similar to sunlight’s spectral curve in order to provide a better growth formula than what is common in conventional LEDs, the firm adds. This results in a more natural and healthy environment for fish, plants and corals while further decreasing algae growth on glass.

Light sources with SunLike Series LEDs are also said to more accurately show the color of objects as they would appear in natural sunlight. Optimized to natural light spectra and color rendering of CRI-97 (close to CRI-100 of sunlight), and higher than the CRI-80 of conventional LEDs, SunLike Series LEDs also deliver benefits in vivid color, contrast detail, and quality of light consistency, the firm says..

“Our SunLike Series natural spectrum LEDs as healthy light sources will offer the considerable benefits for better growth of fishes and plants in aquarium, compared to conventional LEDs,” says Carlo Romiti, Europe sales VP.

Seoul Semiconductor developed SunLike Series natural-spectrum LEDs in collaboration with Toshiba Materials’ TRI-R spectrum technology in 2017 as what was claimed to be the first LED light source to closely match the spectrum of natural sunlight.
