All of the fixtures in the living room, kitchen, and dining room were manufactured by Capital Lighting. You can buy these from a local lighting store or through an online lighting store. Here are model numbers and links to the fixtures on the manufacturer's website:

Living Room Center Chandelier (3938WG-475) = http://bit.ly/ye4ag6
Living Room Outside Fixtures (3931WG-481) = http://bit.ly/weSTAQ

Use Google Shopper to find the best prices online. I did a quick search and found the center chandelier for as low as $480. The outside fixtures (of which we have four of them in the living room) are available online for as low as $280. We bought ours from a local lighting store that was trying to clearance them out of their showroom, so we got an amazing deal.
