I've a bit of a sucker for style over substance. For me, lighting should be beautiful as well as practical and sometimes I have to remind myself to focus a bit more on the latter!
I love chandeliers, and have them in almost every room of my house, even one one the bathrooms (you can just see a bit of it here) and yes, I have had this approved as legal for my electrical safety certificate.
In the living room, I have the most enormous chandelier. It's four foot high. When I bought it, the builders said, "You're not furnishing Buckingham Palace you know..." but with the high ceilings, I thought I could get away with it 🙂 On the ground floor, the ceilings are not very high, so apart from the chandeliers over the dining table (where no one is going to hit their head), I've had to go for flush lighting on the ceilings and wall lights.
On the practical side, I really think that a bedside lamp is an absolute must. Mine are quite pretty, but there are so many affordable options out there, I just don't understand any host that doesn't provide a bedside table and lamp.
On the less practical side, I also have some lights that are purely decorative. In one of the bedrooms, I have a cherry blossom light similar to the below trailing around the side of a mirror. It serves little purpose other than being pretty and I have added a couple of little (fake) birdies to the branches as the room has a little bit of a bird theme.
