The KZ Fiji purple is a less harsh in the red areas and seems to have a bit more violet. The super purple is close to the FP looks wise. The ATI purple plus is the harshest to my eye.
The FP also had higher par than the other purple bulbs when I tested the bulbs I had on hand.
I am not wild about the ATI, seems a little too red at times but I need it to balance things out. So, I will give the KZ a shot. As always...thanks.
