[0068] In at least one implementation, at least a portion of the shade 50 may be substantially transparent and may incorporate a phosphor (e.g., a europium doped strontium-barium silicate phosphor, such as P/N O5446 available from Intematix Corporation) which operates as a wavelength shifter or converter to convert shorter wavelengths (e.g., 440-480 nm wavelengths, 400-490 nm wavelengths) into longer, more desirable wavelengths. In at least one implementation, at least a portion of the shade 50 may be substantially transparent and coated with quantum dots which convert the shorter wavelengths (e.g., 440-480 nm wavelengths) into longer, more desirable wavelengths. The coating of quantum dots may be a coating available from Quantum Materials Corporation, San Marcos, Tex., for example. The longer wavelength light may be projected onto the residential area (house side) in addition to some part of the original higher color temperature light, thereby lowering the color temperature of the light on the house side (HS) while retaining higher color temperature light on the street side (SS).
