1. An LED light assembly comprising:

  • a first beam forming optic and a second beam forming optic, each of said first and second beam forming optics having a focus, said foci intersected by a linear axis;

    a first light emitting die and a second light emitting die, said first and second light emitting dies arranged to emit light into said first beam forming optic and said second beam forming optic, said first light emitting die emitting light of a first or second color and having an optical axis passing through the focus and said second light emitting die emitting light of the other of said first or second color and having an optical axis offset from the focus and intersecting said linear axis;

    wherein said first light emitting die emits light of the first color into said first beam forming optic, said first light emitting die emits light of the second color into said second beam forming optic, and said light emitting dies emitting light of said first color are energized at the same time so that light of the first color is emitted at the focus of the first beam forming optic and offset from the focus of the second beam forming optic and said light emitting dies emitting light of said second color are energized at the same time so that light of the second color is emitted at the focus of the second beam forming optic and offset from the focus of the first beam forming optic.
