An incandescent light bulb has a CRI of 100. [1] High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.
Researchers use daylight as the benchmark to which to compare color rendering of electric lights. In 1948, daylight was described as the ideal source of illumination for good color rendering because "it (daylight) displays (1) a great variety of colors, (2) makes it easy to distinguish slight shades of color, and (3) the colors of objects around us obviously look natural".

Thermal management is a universal problem having to do with power density, which occurs both at higher powers or in smaller devices. Many lighting applications wish to combine a high light flux with an extremely small light emitting substrate, causing concerns with LED power management to be particularly acute.
The house above appears a light cream during midday, but seems to be bluish white here in the dim light before full sunrise. Note the color temperature of the sunrise in the background. Video camera operators can white-balance objects that are not white, downplaying the color of the object used for white-balancing. For instance, they can bring ...

This causes the white LED lights to turn blue or purple. [18] The issues of large scale defective lights happened in many cities in United States and Canada. [19] [20]
