Multi-wiring one flourescent light fixture...

I would like to add additional fluorescent drop-in fixtures to our drop ceiling in the basement. I'd like to install fixtures with three bulbs in each. I know that these can be wired up (assuming the ballasts are wired correctly) so that one switch on the wall turns on the middle light, and another switch turns on the remaining 2 outer lights. I'd like this option so that I can have bright or dim lighting depending on whats going on in the room.

I have searched google but I'm not sure what this type of wiriing is called, and how it is accomplished.

Any help would be most kind.

It pretty common for alot of commercal locations to have dual circuit flourscent luminaires so they have switching option just like you describing so one circuit for one lamp while second circuit for two lamp and yes that is common.

Sure they will cost little more than standard verison.

You can find them in electrical supply centre however some of big box store may make a specal order for ya.

I could run cables among the fixtures and rewire things so say the ballast in one unit (and corresponding wall switch) operates the left tube (lamp; bulb) in all the fixtures and the ballast on another unit operates the center tubes etc. But each ballast has to operate the same number of tubes it did originally.
