Even high cri lights have a huge blue spike that doesn't match the sun. I don't know what chip OP uses, but you need a full spectrum light if you actually want very sun-like light. This page has some details:

No idea if there's any evidence or not of the blue spike actually mattering for human biology.

Kind of what I worry about—the spectrum mismatch. Damn but incandescents sound pretty good for just this one application. I must be (am) getting old.
