Sorry, I should have said ballast equivalent circuit, whatever it is, the
fixtures are old and I can't replace those. I'm really more interested in
PoE for setting lighting times and intensity and also strategic placement
of overhead strip and floorboard night lighting.

Also I have a floor to ceiling nook area where I'd like to grow herbs. Its
too irregular a shape for even adequate storage but a couple of shelves for
basil etc. could fit nicely. I'd kind of be in violation of the fire code
if I had a bunch of 110v cords running from wall outlets, so I'd thought
I'd look at integrating my general lighting with grow lighting. If only to
reduce the amount of tech I have to throw out periodically.

It might be cost effective to replace the entire buildings lighting, but I
don't see that happening any time soon.
