Understanding CRI In Relation To LED Lighting

When you’re dealing with LED lighting, there’s a term that frequently comes up: CRI (color rendering index). Before buying any LED light bulbs it’s important to know what this term means and how it relates to these lights.

How CRI is Defined

Sometimes you may find it hard to tell the difference between black and. Oftentimes this is because the source of your current lighting doesn’t have a high CRI rating. This is just one of the many ways in which you’ll discover that not every light is made in the same way. Simply put, this is a measurement that will tell you how various colors look under LED lighting in comparison to how they look in natural sunlight. The index consists of a scale of 1 – 100 on which a score of a perfect 100 indicates that these colors will look the same as they do in natural sunlight.

Additionally, this measurement also helps discern various other things, including:

  • Preference
  • Naturalness
  • Color harmony
  • Vividness
  • Color naming accuracy
  • Hue discrimination

Important Information About This Measurement

When you’re working with this measurement, it’s important to understand that:

  • Lights that measure over 80 are considered more than acceptable for the majority of applications
  • Any rating of 90 or above is considered “high”: These are the lights that you’ll want to use for things like photography, retail displays, grocery stores – essentially anywhere that it’s vital to accurately represent colors. This can also be beneficial in your home if you want to show off a room’s design details or create an overall feeling that’s both natural and comfortable.

How This Measurement is Determined

To test for CRI you’ll need some special machinery. It will analyze the light spectrum of LED lighting and breaks it down into 8 different colors that are known as “R values” (R1 – R8). All together there are a total of 15 measurements, but this test only sees the first 8. Nevertheless, the LED lighting is still scored 0 – 100 for each color depending on how naturally rendered it is when compared to what looks like a “perfect” light that’s the same color and temperature.

Any LED lighting that has a high CRI value will offer you the best of everything. It’ll use only a fraction of the energy that traditional lighting uses and yet you get beautifully vibrant tones across the whole color spectrum. Of course, these are only a few of the many reasons why you should take notice of this type of LED lighting. So, when you buy new lights make sure you look for this information on it. Most manufacturers are now including it there since the government is incentivizing them to do so.

Regardless of whether you have questions about LED lighting or you’re ready to install it in your home or business, you’ll want to work with an expert like those you’ll find at America’s Best LED. Over the years they’ve helped many clients successfully upgrade their lighting and yours should be next.
