track lights dont need plaster ceiling and you can keep adding light fixture and place them wherever you want. but use led track light

you can also use surface mounted downlights but you need to pull wiring to add additional fixtures. unless you can tahan surface mounted wiring with some sort of trunking to conceal the wires

actually you can just put one or two decent size chandelier/ceiling light and that should be enough to brighten up say a living room. Then you just add additional table or floor lamps.
