thanks for posting that ScubaSteve, now I don't have to type a long one like you did.
It will suffice to say, that I agree with you 100% PAR is only one part of the equation, fluorescence and its manipulation are another. and there are several colors which are activated under 400nm.
Dana Riddle, has written a series of 5 articles on this starting with this one in 2006

there a real good read, and have a lot of info.
now if you don't want particular colors then don't include the activation wave length range in your lights. but if you want them you need to cover quite a range.
