T5 Q's

Very true, the variables in grim reefers testing of bulbs were never noted but his tests have been very useful with buying bulbs

Pure actinic's are useless. Its like walking around with a black light and seeing what they form of lighting is doing to the colors around you, only visual changes. T5 bulbs rated at 22,000k are very benifical and in my latest changes I am starting to notice my blues pop alot more. As for the DUO comments, yes they are a very white bulb for their kelvin rating but with the hint of red spectrum in them and running them for a month now i believe i am starting to notice my reds coming back. Great bulb

To the OP If i were you i would pure three 22,000k rates bulbs in and maybe a fiji purple. If your adding suppimental bulbs why not put something worth while in?
