Yes. One entry in Table 9 of Annex XI reads “CRI and R9 [0-100]”. The 0-100 range applies only to CRI and not to R9. This is in line with the definition of light source in article 2(1), with CRI that should be >0. In EPREL it is correctly allowed to register a value in the range - 100 to +100. This may be clarified in a later amendment to the Regulation.
