Graham Sutherland / Polynomialthe top-ranked LED by CRI Ra is the GW KAGMB9 KM 5000K, scoring CRI 97.2. it is advertised as CRI 90+. the TM-30-18 CFI for this LED is 92.8, which is very good. the R9 is 89.3.
the top-ranked LED by CFI is the GW KACCBB GM 3500K, with a CFI of 95.3. the CRI is 96 and the R9 is 85.7.
the CRI figure still tells us that it's a good LED in both cases, but can't really be relied upon for evaluating which of two LEDs is better once you're past CRI 90.
