This is for those of us (and you) that may be looking for power compact bulbs that are more in the range of the green-yellow spectrum for your NPT.

I don't have a choice to get any sunlight to my tank, so I went on a search for bulbs that go along the "Cool White" spectrum instead of the general 6700K and 10,000K that we always see online and stores.
In my search I found this website which has bulbs for quite cheap and meet the requirements of more usuable light according to Diana's book.

just navigate to your bulb from here.

Hope this helps for someone.

I couldn't find any Power Compact straight pin bulbs on 1000bulbs.
I ordered the Sylvania 80W 4100K PC bulbs. I just got them in today and HOLY MOLEY!!! It's like high noon on my tank! I know this wont always be good, but I finally have some good light!!
Atlantalights has a MASSIVE selection of PC bulbs, stuff I never heard of.

I will update pics this weekend on flickr. New background and powerhead (JBJ Submariner) going in.
