Despite the current maturity and reliability of white‐light‐emitting diodes (WLEDs), the control of the correlated color temperature (CCT) is still a challenge, arising from the lack of the red color which is often associated with dysregulations of the human circadian rhythm. Warm WLED prototypes were fabricated coating UV‐LEDs with yellow‐ and blue‐emitting phosphors with tunable CCT from 6500 K to 4000 K.
