The Color Rendering Index (CRI)
The type of light bulb you use in your home could have a profound effect on the way a room looks. This is often attributed to something known as the color rendering index. Also referred to as CRI, this index measures the ability of a light source to reveal colors of objects in contrast to a natural light source, such as the sun filtering in through your windows. So, what is CRI? Simply put, it’s the measurement of light in relation to how it affects the appearance of color. This range can also depend on the “temperature” of the light.
Understanding the CRI chart
Every type of lighting has its place on what’s known as the color rendering index chart. This chart measures a scale from 0 to 100, depending on how accurately it can produce light that matches a naturally referenced light source, such as the sun.
In general, bulbs at the higher end of the scale will produce a more accurate color rendering of the objects around it. This can be vital for use in things like photography or commercial lighting used in a stores setting to focus on objects. But it can also affect you and your home. It’s best to choose bulbs that will make your surroundings clear, bright and as close to how they would appear in an outdoor, natural setting.
