The present invention pertains to devices and applications for lamps to produce color mixing effects with a desired color distribution output within a translucent cylindrical housing. More specifically, the invention pertains to a device or devices that utilize a multidirectional light engine constructed in opposite directions with programmed light intensity with a spatial distribution of photons at single or varying wavelengths, which result in a large percentage of those photons entering the translucent cylinder producing a non-linear effect being emitted from the cylinder. Embodiments use two or more coaxial light engines with programmed light intensities producing a variety of non-linear lighting effects, which emit the majority of the light rays in opposing directions within a dedicated color mixing chamber. In some embodiments, the color mixing lighting device comprises two or more coaxial light engines which beam light in a 360 degree radial pattern forming an approximate 110 degree cone.
