I'm not exactly sure what you are saying about them being Parallel. Do you mean Inline?

I believe what you want is the 1 crossbar 3 light system.

That would efficiently cover an 8-10 foot wide room, and you can move it however far you want.

It's better to do a smaller setup with more light in a concentrated area. You will get as much
yield with less plants with more light each plant, as you would with more plants less light each plant.

If you have to section off the room in order to make the inline lights work it is worth it.

Get some Panda film, and some framing, all you gotta do is make a frame and then staple
panda film or white visqueen plastic to the frame to reflect light.

A Standard light rail is 8 feet long, and will move the lights 5 of that 8 feet. Giving an effective
length coverage of 8 feet. and an effective width coverage of roughly 8 feet.

I would say to get two Botanicare 4x4 grow trays, and raise them waste high
(see my raised bed construction in my journal) and do a drain to waste. You could do 24-32
plants in there depending on how long youw want to veg. I am doing 16 plants under 2 600 watts (with no veg),
But i dont have a light mover, you could definitely pull off 32 plants of the same size as mine with 3 400's and a mover.
