The advantages of LED lighting are discussed. We report experiments where observers graded the quality of several light-emitting diode (LED) illuminations. One experiment is based on color discrimination and two experiments are based on the judgement of appearance. We conclude that clusters with red, green, blue, and/or amber LEDs impair color discrimination, although they seem to locally enhance the color gamut. We also conclude that LED clusters that include white LEDs and a few correcting color LED may render colors faithfully.
