With a long room like yours, I would recommend thinking about how you will use the different 'zones' of the room - so for example you may want something soft above the couch, enough to read by but also enough to relax under with a glass of wine in the evenings whereas over the table you may need something brighter for the kids to do their homework (or whatever your lifestyle lends itself to). Where possible I always recommend LED lighting - they are capable of producing both warm and cool light colours and can even be used in accent lighting. They are also very popular for their energy efficiency and they give off almost no heat which is an added safety feature.

Two issues -- The middle size looks 'about right' and approx 40cm diameter ( approx 2/3rds the size of the larger one ) . But I don't think it suits many modern styles -- a beach inspired place with say white woven wallpaper or seagrass style flooring or some distressed furniture would be complemented by this , but a modern build with say painted walls doesn't do anything with this style IMO . Go classier rather than laid-back would be my advice , and that would depend on the decor . And thinking about things , one 'trick' I used in a commercial building I own was 5 polished copper shades up an L shaped stairway -- the ceiling was flat , so nearly 5 metres 'up' at the base , and I used 28cm ones with the biggest round clear LED bulbs ( 8Watt ) I could get , all hung on that oldstyle '1940's iron' type cord , so they were all 2.6metres above the stair below -- it created that 'going up' visual effect . One large light ( especially say 4 metres above the deck ) won't give that effect .

brushed nickel sounds good to me

Thank you for your responses. Both areas are separated by a bulk head in the kitchen with the kitchen light a bit hidden by it. The dilema is that the dinning have traditional beige courtains with rectangular palmets and there is nothing black on it should i choose something that matches the color of the kitchen which is predominately black and beige or  something that matches the colours of dining wich are beige with the same colour of the wood as the shutters in the kitchen ( honey colur). I apreciate your feedbak.  Thank you.
