Abstract:
In some embodiments, a composition comprises a bisphenol-A polycarbonate, wherein a molded article of the bisphenol-A polycarbonate has transmission level greater than or equal to 90.0% at 2.5 mm thickness as measured by ASTM D1003-00 and a yellow index (YI) less than or equal to 1.5 as measured by ASTM D1925. In some embodiments, light emitting device comprises: a lighting element located in a housing. The housing is formed from a plastic composition comprising: the polycarbonate composition and a conversion material. After the conversion material has been exposed to an excitation source, the conversion material has a luminescence lifetime of less than 10−4 seconds when the excitation source is removed.
