Remark: We've innovated one kind of single phosphor with different CRI and efficiency to satiisfy our high end clients' demand for high CRI and effiecency products. This sort of phoshpor has gone through the normal and aging test high temperaure&high humidity aging. High&low temperature, thermal cycling test. We suggest that you adopt chips of band 455-460. The higher band, the better performance.
