not sure exactly what you are asking.
These were used to drive 4 T5 bulbs in 36" light fixture, 2x39w bulbs per ballast. i just unplugged them. There is a 4 contact round quick disconnect plug on each ballast, if you don't want to use a plug the wires can be cut and wired straight to your fixture T5 bulb connectors, like you would any regular house two bulb light fixture.

I am not an electrician but i think something like that except you will have two not 3 bulbs.

Ok i see what you mean now by retrofit.
yes if you want to add two more bulbs you will need a room for two more bulbs in the fixture and a ballast that will drive these extra bulbs.
or
If you have a canopy then you will also need a reflector or individual reflectors in addition to the extra ballast and bulbs.
