Which light source has a CRI of 100?

• A. Incandescent
• B. T8 Linear Fluorescent
• C. Daylight
• D. LED

Answer: (D)

CRI 100 means colors render exactly the same as they would under a perfect reference light. LEDs can be designed to cover the visible spectrum evenly with carefully chosen phosphors and spectral balancing, allowing high-CRI LEDs to reach or closely approach that perfect 100. Because of this ability to engineer the spectrum for faithful color reproduction, LEDs are the best match when a CRI of 100 is specified. Fluorescent options typically don’t reach 100, and daylight is used as the reference point for CRI rather than a target you choose for a light source.
