Yujileds® HE series LED technology aims to provide the superb luminous efficacy to match the increasingly demand of energy saving for commercial lighting industry. By providing up to 210lm/W (60mA at 6500K) and appropriate lighting design, the HE series technology helps to achieve A-class of the latest European Product Registry for Energy Labelling (EPREL) and DLC Premium.
Technically, luminous efficacy and color rendition is difficult and contradictory to get both promising. Yujileds® HE series LED overcomes this by achieving up to 210lm/W and 90+ CRI when the general high luminous efficacy LEDs are all 80 CRI. Even for pursuing the extreme efficacy, the CRI should not be sacrificed since it is a nature of illumination quality. Even for the advanced color metric of TM-30, Yujileds® HE series LED performs the same as nominal high CRI LED with Rf 90 and Rg 99.
For general commercial lighting, calculating lm/$ is a common method to evaluate the economic efficiency of LED business and it becomes a measurement for commercialized competitive force. Yujileds® HE series LED provides the promising lm/$ based on its better color quality to help customers win the business and higher profits simultaneously, thus the HE series redefines the lm/$.
