In embodiments, a first light engine produces a first light spectrum having a first CCT. A second light engine produces a second light spectrum having a second CCT. The first light spectrum is emitted from a first region of an enclosure; a second light spectrum is emitted from a second region; and a mixture is emitted from a third region that separates the first and second regions. The second CCT is less than the first CCT; a difference between the first and second CCTs is at least 10,000K. The first light spectrum may have a first emission peak in a range of 450 to 480 nm and a second emission peak in a range of 380 to 420 nm. The second light spectrum may have a third emission peak in a range of 480 to 500 nm and a fourth emission peak in the range of 450 to 480 nm.

Color separation lighting devices

Lighting apparatuses include an enclosure around first and second light engines. The enclosure has a diffuser over first, second and third regions. The first and second regions are separated by the third region; a first light spectrum is emitted from the first region; a second light spectrum is emitted from the second region; and a mixture of the spectrums is emitted from the third region. In some embodiments, the first spectrum has a CCT&#x2265;7000K; the second spectrum has a CCT&#x2264;6500K. In some embodiments, the first spectrum has a first CCT&#x2265;3500K; the second spectrum has a second CCT&#x2264;6500K; the second CCT&#x3c;first CCT and the difference between the CCTs is at least 1000K. In some embodiments, the first spectrum has a color bounded by a first set of chromaticity coordinates, and the second spectrum has a color bounded by a second set.
