The Morimoto brand has what could be called a "criminal record" -- for many years every single item under that brand was just blatant garbage, completely illegal/non-compliant with safety regulations, etc. More lately they've been beginning to put out some products that are moving in the direction of legitimacy. Even still, they're designed to appeal to "tuners", which is a word that basically means children. If you don't like 6000K-6500K blue-white light with a big, deliberate blue-violet band above the much too sharp cutoff, then these are probably going to **** you off. However, their performance overall is objectively better than the headlamps Ford installs at the factory (halogen or LED), so it's pretty much a pay-your-money/take-your-choices kind of deal.
As far as CRI goes: poor, just like every other LED headlamp, whether OE or aftermarket.
