EVERLIGHT’s Natural Light Technology campaign addresses market requirements for higher quality of Li

18. 9. 2014 | |

EVERLIGHT ELECTRONICS CO., LTD. , a leading player in the global LED and optoelectronics industry, supplements its LED Lighting product portfolio, currently featuring a market-standard CRI of > 80 Ra, with higher color quality versions. The new Natural Light LED variants will provide a CRI >95 Ra, averaging 98 Ra. EVERLIGHT is pursuing this goal a step at a time. The first LED series to implement the Natural Light Technology is EVERLIGHT’s 3 - 50W Ceramic COBs (JU Series) and Metal PCB COBs (XUAN Series). All other LEDs will offer Natural Light versions in Q4 of 2014. 

Color rendering, a quality characteristic of light, is the effect of an illuminant on the color appearance of an object by conscious or subconscious comparison with their color appearance under a reference illuminant. One major objective of LED lighting manufacturers is to achieve a light quality that can replace or emulate the ultimate reference of the sun. In other words: a CRI of 100Ra. To reach this goal would bring sunlight indoors, sustain sunlight during the night, replace traditional incandescent and halogen lamps which usually feature high color quality, and change the way we perceive and appreciate our surroundings.
