According to the Light Research Center (LRC) at Rensselaer Polytechnic Institute, the world's leading center for Light Research and Education, “The circadian rhythm is defined as the circadian cycle that repeats approximately every 24 hours. Light is the primary stimulus that assists the biological clock in functioning and keeps the circadian rhythm in sync with the 24 hours of the day. Without this synchronization, it is shown in the research that we can experience long-term impairment in physiological function, neural activity, and sleep quality, a higher risk of cardiovascular disease and diabetes, as well as some more advanced forms of cancer,". Light is said to be the most important factor to put an influence on work performance, alertness, sleep quality, and health.
Recognizing the significance of light in the body's daily rhythms, human-centric lighting (HCL) design has emerged as a dominant trend in the global LED lighting industry today. Human-Centric Lighting (HCL) is a technological revolution that produces light that is similar to natural daylight, thereby promoting body functions and enhancing work performance, comfort, human health and happiness. With the philosophy of "Lighting for human health", Phenikaa is proud to be the first Vietnamese lighting brand that provides users with a unique lighting experience. It is the result of research, design and successful manufacturing of a completely new product line approaching HCL technology comprehensively considering the effects of light to create light sources that meet both the balance between visual and sensory, emotional and biological needs of the customers. PHENIKAA HEALTHAA - the first lighting product in the market that meets both criteria of natural light quality (CRI = 95+), red reproduction index (R9 = 95) and enhanced bio-light energy (M/P = 1.04 - 1.18), enabling to improve light efficiency and quality, supplement bio-light, and optimize for human health. This is a high-end product line of Phenikaa Lighting, increasing alertness and concentration, assisting our mind and body in achieving a healthy, refreshing state.
