I actually added the AI Fuge Light the same day I posted this thread and after just 10 days there is a big noticeable difference in the way the chaeto in my refugium looks.
I do have to admit my previous bulbs ( 5k led spot bulbs) I used were pretty old. Maybe 2 years or more.
The growth has exploded.
And it looks really dark green.
I just need to find another smaller light for a 15" x 6" refugium on my small tank that has similar leds as the AI.
