Yujileds® HE series LED technology, up to 210lm/W
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.
Color quality is no longer compromised to high luminous efficacy
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.
Redefine lumen per dollar (lm/$)
For general commercial lighting, calculating lm/$ 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/$.
