Last Updated: 30th May, 2020
|Light source||CCT (K)||CRI|
|High-CRI LED lamp (blue LED)||2700–5000||95|
|Ceramic discharge metal-halide lamp||5400||96|
|Ultra-high-CRI LED lamp (violet LED)||2700–5000||99|

Simply so, what is the CRI of halogen lamps?
Halogen lamps have a good colour rendering level, namely 100, but their low energy efficiency and short lifespan, around 2.000 hours, are to their disadvantage. On the other hand, energy-saving light bulbs have a slightly lower CRI, which is however a good one, that is 80, and last for around 6.000 hours.
Secondly, what is a good CRI? Typically, light sources with a CRI of 80 to 90 are regarded as good and those with a CRI of 90+ are excellent! The general rule is: The higher the CRI, the better the color rendering capacity. CRI is independent of color temperature.
Besides, is a CRI of 80 good?
CRI is a convenient metric because it is represented as a single, quantified number. CRI values that are 90 and above are considered excellent, while scores below 80 are generally considered poor. (More on this below). Light sources can be grouped into either artificial or natural light sources.
