They sell several versions. The link is for 10 standalone bulbs that use a 3 prong laptop style or 2 pin electric shaver style power cord if you dont want to run a ground. They are standalone in that they dont need a fixture, tombstones or any kind of end brackets. They include a plug in 12 inch power pigtail.
The other versions are if you want to use existing fixtures, removing the ballast and connecting power through the bulb end terminals. I wanted to use the simpler version and remove my metal fixtures entirely. They also come with small metal brackets to screw directly to the ceiling and the tube aluminum back snaps into it fir a flush mount on ceiling.

These weigh less than 1 pound each nut are very rigid and wont flex much.
