When does one buy lights?

Have open concept LR DR kitchen and entrance hallway. Kitchen cabs not getting installed till end of summer.

Am thinking lights should be tied up together by some concept, right?

How does one goes about tying all elements together?

I know i want to follow simple scandinavian design with clean elegant lines at modest to moderate prices.

I am looking to replace entrance hall lights and I need 2 of them. Not sure how to go mixing and matching other lights though...

Any suggestions?

There is no rugs or furniture or floors yet. I am not buying furniture until floor is installed and not getting floor in until kitchen cabs in. However hallway LR and DR are painted.
