Just for fun, let's eyeball CRI and CCT of these COBs

Let’s play the game shall we? These are some of the COBs in my collection. I put some of these on display in the pic.

The rule is simple, just guess the CRI and CCT of these COBs in the picture.

I will show the answer some time later.

PS. Not only I have turned into a flashaholic, but also emitter collector. Dear god what have I become? :person_facepalming:

CRI and CCT is one thing
having a neutral tint and good efficiency is another

just for a customer work light upgrade I bought one of those nice top binned ones

Of course, tint and efficiency is another thing to consider. Although these COBs are simply meant to be put on display, because reasons (unless a circumstance requires me to use one of these).
