The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module, configured to generate a visible light such as white light, and at least one component such as optical component comprising a compound consisting essentially of the elements neodymium (Nd) and fluorine (F), and optionally including one or more other elements. The lighting apparatus is configured to provide a desired light spectrum by filtering the generated visible light using the compound. The at least one component can comprise a NdFOcompound with values of x and y determining a content ratio F/O, which may be adjusted during manufacturing of the NdFOcompound to provide desired output light parameters of the apparatus including at least a desired output light spectrum realized by filtering the generated visible light using the NdFOcompound.

The specification and drawings present a new apparatus such as a halogen incandescent lamp is presented herein, the apparatus comprising a light source such as a light-generating element made of tungsten, configured to generate a visible light such as white light having chromaticity coordinates of the light source in a clear center in a color space, and a component such as light-transmissive envelope, enclosing the light source and comprising a coating with a compound comprising elements of neodymium and fluorine and configured to provide a desired light spectrum by filtering the generated visible light using the compound, where the desired light spectrum having chromaticity coordinates in the color space being shifted from the clear center below the black-body locus and outside of a four-step MacAdam ellipse of the light source to meet a predefined requirement for a modified spectrum lamp.
