Kitchen diner lighting help

[ExtendRoundTheBend]

Hi, this shouldn't be keeping me awake but it is!
We're having a small extension and will have a new kitchen diner, open to a family room. The kitchen diner part will be approx 3.5m by 5.5m wide, with the kitchen at one end in a U ish shape with a breakfast bar with stools dividing the kitchen and dining parts. I had planned to put some pendant lights above the breakfast bar but think it may be a bit much with spotlights in the kitchen and another pendant light in the dining room? Is the room big enough for all of that?
There will be no roof lights as pitch is too shallow (although ceiling will be vaulted). I would have the same light fitting in the family room as in the dining part as these rooms will flow in to eachother.
I'd appreciate any guidance and advice please!

You can never have Too many lights in a kitchen diner. If you don't have them above the breakfast bar it will be dark

Ours are on a 1200x1200 grid.

Thanks both. I definitely don't want it to be dark! I think we've decided to have spotlights across the kitchen and dining areas and pendants over the breakfast bar. Otherwise it could look messy if I have another pendant over the dining table as it would be close to the breakfast bar pendants.
I don't understand what you mean Humpty about the 12 x 12 grid? What size is your space?

We have same set up. Pendant over dining table, 3 lights over breakfast bar and spots everywhere. It means can vary lighting as we want. We also have wall lights in extension

If you look at the panoramic or plans on this you will see a 1200 grid set up for the LED lighting . This is the same type of set up as ours as was done by same designer.

Hi again. The breakfast bar will be approx 6ft, I have my eye on 2 pendants that are 45cm diameter each. Will they be too big?
Sorry this feels like a school algebra question!
