Spectrum Designer

Mix LED die, phosphor and packaged-LED spectral libraries and watch the resulting spectral power distribution, CIE chromaticity, CCT, Duv and full CIE 13.3-1995 color rendering index update live — the same calculation used in real spectral LED engineering.

For CRI/R9 background first, see our High CRI LED Lighting Guide or try the CRI Comparison Tool .

For an accurate simulated color and comparison, view this on a properly color-calibrated display — uncalibrated screens and "vivid" color modes will distort the result.
