1. A LED array comprising;

  • a first color string comprising at least two first LED die emitting about a first selected wavelength, λ

    s1, and first selected range, ±

    r1, wherein the at least two first die comprise one die emitting at a wavelength shorter than the first selected wavelength, λ

    s1, minus the first selected range, r1, and one die emitting at a wavelength longer than the first selected wavelength, λ

    s1, plus the first selected range, r1, such that the average weighted wavelength, <

    λ

    aww1>

    , of the at least two first die is within λ

    s1±

    r1.
