Abstract— In this study, we propose a low cost solution to produce light having a color rendering index (CRI) of 90 and color temperatures of 4000 K at 1000 lm. On the basis of commercial light emitting diodes (LEDs) from companies C, O, and P spectral data were collected. One solution is
evaluated using the color mixing results for a high quality lighting environment.
Index Terms— SPD, cost.
