BG574816559 Color Rendering Index-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. For example, lighting temperatures can range from infrared light to the kind coming from a skylight, all the way to ultraviolet light. Ideally, you want to use lighting that will best illuminate each room depending on your needs. In terms of CRI for LED, most LED lights produce a score of about 80 to 90 on the chart. The result is a brighter room, but with a much more natural, accurate output of light. Unlike fluorescent lighting which can create an unnatural look, LEDs are better suited to indoor environments. Aside from the color rendering index, the number of lumens output, or actual light produced, plays a role in the overall effectiveness of an LED bulb too
