Promolux designates its proprietary color formulas by names, rather than numbers (Platinum, Premium White, HD35). Because the Promolux color spectrum is fine-tuned to ensure the best merchandising and protection, a CRI or Kelvin number is not a useful way to understand the color of Promolux LEDs.
In August 2014 the Illuminating Engineering Society (IES) wrote a position statement finally recognizing that CRI is an outdated metric with shortcomings, “that limit its ability to fully represent how humans perceive color.”
The only real way to know how good a particular LED is at showcasing foods’ natural colors is to see it. How does it make the product look? Is it a vibrant display? Are the reds, “red” and the whites, “white”, and so on? One simply can’t rely on numbers on a piece of paper (ie. CRI, Kelvin, etc) to answer those questions – it’s impossible. You have to see for yourself.
All this being said, if you would still like to know the CRI & Kelvin’s, give us a call toll free: 1-800-519-1222 and we’d be happy to provide them.
