The Salud LEDs are claimed to be the first with datasheet specified melanopic ratios (MRs) in addition to CRI, R9, CCT, and Flux. By enhancing the spectrum with cyan for melatonin suppression and enriching the 660nm emission for natural skin tones and excellent red-rendering, Luminus Salud LEDs can deliver warmer, more comfortable light that keeps people healthy, alert, and productive.
Scientists studying human circadian rhythm and the physiological reaction to light have determined that low MRs are a signal to the body to prepare for sleep, and higher MRs tell the body to be more alert. Standard warm CCT LEDs (3000 K to 4000 K) commonly used across the lighting industry have low MRs, which can reduce alertness and productivity. Cool CCTs have high MRs and people are generally awake and alert in this light. However, in offices and other public spaces, such cool CCTs are considered too "blue" and typically not desirable.
