isn't that a contradiction since Actinic light is defined of having a peak wave length of 430nm?

Okay, Okay
Rather than continuing a useless argument how about saying a bulb that peaks somewhere around 460nm will show good coral fluorescence
I have a 460nm tube that gives great coral color. I also have a dual element 460/420nm tube that gives equally good color rendition.
