I tend to always leave lighting for the end, and then scramble around the various suppliers to find some last minute pieces. The good news is the large hardware stores have started to stock replicas of the really expensive designer stuff at reasonable cost. And all the new stuff tends to be integrated LED, which was unobtainably pricey just a few short years ago.
Similar fixtures that are now in customized LED with shapes and styles that can't be easily made used to be lit by G9 style halogens. Those were the kind of bulb that often blew out prematurely and were hard to replace, burnt really hot, and sucked a lot of power. Often you'd see a bathroom light with 3-4 x 60 watt halogen. That is way too much electrical use for one fixture.
We will be starting the interior completion of the project shortly, that means we are going to do the lights and plumbing first, the hardwood second, and then the carpet and appliances at the very end. It is always nice to be at this stage of the project because the end is definitely near.
Round shaped LED fixture are now available at your local hardware store.
