Not sure what you may have decided about lighting, but consider these.

I replaced all my bulbs in the house with them, and so far so good. DO NOT even try the ballast, just go ahead and take it out. No sense in using the extra energy.
If you do not have any fixtures yet, you could just buy some tombstones and mount them directly to the ceiling with some shiny or white painted sheet metal underneath. They sell the tombstones cheap on the same page as the bulbs.
The sheet metal would aid in reflection and shield the ceiling from heat or a catastrophic short.
If you do it that way, you need to either come in from above at each end, or fabricate some kind of cover for the wire going from one end to the other.
The instructions might be a little vague. Both pins are tied together on the ends, and you just need to hook 120V from one end to the other.
I put one in a dual 40 watt fixture, and it was brighter than the two bulbs it replaced. I just left the one in, two were too bright for that room.
It is a little directional. If I were starting from scratch, I think I would put the bulbs along both sides of a large room with them angled slightly towards the center.
Tombstones come in two types. Shorting and non-shorting. Some LED replacement bulbs use the two pins on the end separately, and the two pins must not be tied together. So a shorting type tombstone would not work. And unless you check your present fixture, you never know which yours has. That is one of the reasons I bought this model. It will work with either type. If yours is the non shorting with two wires, just tie them together and hook them to one side of the 120V line.
I see some bad reviews on that page, but I suspect most of them tried to use the original ballast and got discouraged when it did not work.
I did have a little trouble putting the bulb in, it is slightly longer than standard, but the connectors bent enough to make it work.
