@Neryl, you cracked me up when I read your post ha-ha @lakshmi17, All jokes aside, if you want to go to the trouble of having beautiful pendant lights and your ceiling is so high, get a professional!!! Save up if you have to but it's the best way to go in this case, you might be surprised that it's not as expensive as the cost of the lights you intend to have fitted. I paid over $130 for each of the three lights I have bought to have installed over my dining table and I'm darn sure my electrician won't be charging me $400 to install them!!!

Yes definitely consider your furniture placement. Your lights should connect to the rest of the rooms decor. That is over the coffee table or over side tables. A cluster might work if you vary heights and consider some changes in size and shape of each light. See some examples below. Your light choice is lovely. It will however throw that pattern all around the room, something to think about if it's to be your only light source. You say there will be a fan as well. This will make the pendants move, another point to consider.

If you are in New Zealand, I have often found great lights (and a big range) at Lighting Plus. When I was putting my house on the market I put three of these: http://www.lightingplus.co.nz/lighting/pendants/contemporary/jaga-bcopal-1light-pendant.html over my kitchen benchtop, and they looked just gorgeous. So gorgeous in fact, that I have already bought three new ones in advance for when I upgrade the kitchen lighting in my new house. They also have these : http://www.lightingplus.co.nz/lighting/pendants/contemporary/hudson25-whitegold-1lt-pendant.html or these: http://www.lightingplus.co.nz/lighting/pendants/contemporary/trumpet35-pendant-blackgold.html  if you like the look of the internal gold under the shade. There are also others similar. I have also found some great lights at : http://www.edenlighting.co.nz/collections/pendant-lights . All of these are very affordable. However if you want to go really high end, and you like NZ timber lights, you can't go past : https://www.davidtrubridge.com/collection/lighting/  Just my 2c. Enjoy.

Hello Northstar 1 thing to remember when choosing your lights .If you want the light down choose a down facing lampholder, dont drop them to low as the GLARE from the globes in your eyes every time they are on is annoying as, every lit pendant you showed had an incandescent globe so if your going to use Fluro globes they will look worse.LED globes with a cleeear glass would be best. Avoid carbon filament even though they look great its a low light output. Depending on your budget take a look at Mondoluce on line they have some amazing glass pendants from Italy and in multiple sizes.
