In the published data for White Luxeon and Nichia LEDs the spectral power distribution is very similar with the exception that the Luxeons have a prominent narrow peak at around 610nm that is not present in the Nichia spectrum. Nichia uses YAG as the phosphor but I have not seen any Luxeon literature that discusses their phosphor choice. It appears that they may be using a mixture of YAG and a second phosphor that gives that 610nm peak. Does anyone know?
