Nichia Optisolis LEDs: Revolutionizing Lighting in Museums and Galleries with Sunlight-like Illumination

Nichia Optisolis LEDs light art museums across Germany and Japan

The innovative Optisolis LEDs from Nichia have a light spectrum that closely matches the spectrum of natural sunlight.

The extraordinary result is achieved by using a revolutionary new phosphor technology and special blue LED chip. The spectrum of the 420nm blue chip contains almost no UV emissions and in combination with the phosphor achieves a CRI value of 98+, an ultrahigh number considering sunlight has CRI 100.

The Nichia Optisolis LEDs high quality of light renders colors accurately and adds the benefit of increased awareness of contrast and texture. In combination with their very low UV emissions, Optisolis light fixtures and LED strips are particularly suitable for use in museums and art galleries where the highest possible CRI value is preferred without damaging the valuable works of art with UV rays.

Many museums in Germany have implemented the Nichia Optisolis lighting, among them: Zeppelin Museum in Friedrichshafen, the Ludwig Museum in Koblenz and the Picasso Museum in Münster.

Introducing Nichia Optisolis LEDs: Harnessing the Full Spectrum of Sunlight for Various Applications

NICHIA Ultra-High CRI: Optisolis™ LED emitters’ natural light closely matches spectral profile of sunlight.

Introducing Nichia Optisolis LEDs: Harnessing the Full Spectrum of Sunlight for Various Applications

The world market leader in LED development, Nichia, has unveiled its latest innovation: the Optisolis™ technology. Optisolis™ LED emitters provide a natural light source with a spectrum that achieves the industry's closest match to that of standard illuminants, sunlight, and incandescent artificial light, boasting a color rendering index (CRI) of over 98.


The Optisolis family of LEDs are classified as Ultra-High CRI light sources, as they have maximum scores for all 16 color samples used in the color rendering index metric. The 5000K Nichia NF2L757G-F1 Optisolis LED can even achieve a Ra of 99 out of 100. Similarly, the scores with the new IES TM-30-15 light quality tests are equally high, with Rf at 98 and Rg at 99.
