Following the popularization of LEDs, most luminaires’ luminous efficacy has reached 100 lm/W, the resulting surge in C/P ratio has accelerated market penetration. As consumers become more educated about LEDs, light quality has become the most discussed topic on the market.


In LEDs color rendering performance and color temperature can lower luminous efficacy performance, while three other important color performance parameters color uniformity, stability, and color shift do not have any effect on luminous efficacy.


On the other hand, luminous efficacy without light quality is meaningless. It is important to pursue luminous efficacy, but it would be pointless if light quality is not taken into account. Hence, when manufacturers discuss luminous efficacy, they should consider CRI, SDCM, color uniformity, reliability, and other light quality factors.


The shift from luminous efficacy to light quality is a mandatory trend in the LED industry, in the future competitive lighting products will no doubt shift from low standard level of luminous efficacy demands to developing high quality lighting products that are beneficial to health. Luminous efficacy (lm/W) is only a numerical measurement of lumen output, but light quality emphasizes the quality of the light and the impact of lighting on human health.


Europe and U.S: Advancements in luminous efficacy can simplify the lighting product design, improvements in color rendering performance has made luminaire light quality increasingly similar to sunlight. LEDs are already used to replace halogen luminaires.


Japan: LEDs’ rising luminous efficacy can help lighting products cut energy consumption, which is very important in Japan where power prices are high. Meanwhile, first tier lighting manufacturers are optimistic about energy savings achieved by integrating smart lights with human centric lighting.


China: The majority of LED lighting manufacturers in the country are focused on raising luminous efficacy and lowering costs, while ignoring more advanced lighting applications such as offering comfortable smart LED lights or developing lights beneficial to human wellbeing. Only some high class hotels, retailers, exclusive shops, clubhouses, mansions, and high end lighting projects place emphasis on lighting environments in China. Other lighting application environments tend to have rudimentary requirements.


LED lighting’s new design concept will be increasingly focused on balancing luminous efficacy and light quality, resulting in better LED lighting efficacy and more comfortable lighting environments.
