Im not sure if we are all on the same page. I dont know anything about power usage and all that. But, these are not really fluorescent tubes, they are actually LED bulbs, that fit into the fluorescent socket. They also use 17 watts per bulb, compared to 32 watts for the regular fluorescent tubes.
From what I can tell, they are supposed to be designed as simple as plug and play. In fact the reason I got them was my friend has the same thing and it worked perfectly in their house. I was there to install it and see it myself.
Also, the box of LED tubes does not mention anything about ballasts. There are also no other choices of LED tubes, they only had philips LED tubes available. So if there were other sort of tubes I would be able to look into that and get appropriate tubes.
I thought that "anything you attach fluorescent tubes to" is called a ballast.
see this for example, this looks kind of like some of what I have now:http://homedepot.com/p/Lithonia-Lighting-All-Season-4-ft-2-Light-Grey-T8-Strip-Fluorescent-Shop-Light-1242ZG-RE/202052422
How exactly am I supposed to "directly wire" this sort of thing? Do I open it up, and remove some electronics, then put it back together?
