Technical Explanation: The CRI is a unit that measures the ability of a light source to reproduce the colors of objects faithfully in comparison with an ideal source of light, or natural sources such as sunlight. The CRI is a determined value from 0 to 100, with 100 being the value “perfect” or daylight.
Real World Explanation: The CRI determines how you and your surroundings appear to you and the other people in your environment.
I have borrowed some quotes from the above mentioned article that appeared in “enLIGHTenment” magazine’s July, 2013 issue written by Ted Konnerth, CEO of Egret Consulting Group. A lot of this article is technical so I have selected passages that pertain to consumers.
“Given the recent attention our industry has paid to solid-state lighting, I am sure it is hard for you to believe that fluorescent, high intensity discharge (HID), and incandescent products still represent 85 percent of all lighting sales. I’ve attended and led innumerable discussions at industry gatherings on the emergence of LED. And from what we’ve heard, the future is now. However, new technologies always take time to gain full acceptance. The legacy lighting manufacturers have millions of capital dollars invested in tooling, machinery, and processes that limit their ability to make wholesale changes to their companies. The new entrants have no embedded capital limitations, but they don’t have the channel relationships to push LED adoption at a greater pace. And, their limitation of lighting expertise limits the ability to match LED’s benefits with lighting application expertise.
