Our new house was somewhat overlit when we moved in: if all the lights had been working and turned on at once, they would have drawn nearly 1.5kW. There were twelve lights that weren't working, because of dead transformers or blown bulbs, but such was the redundancy that replacing those didn't seem urgent. It did, however, give me an opportunity to switch a huge variety of halogen bulbs to LEDs or compact fluorescents. more
One of the things we inherited with our house was a folder of photos and documents of an owner from the 1950s, in one of which the house carries a sign "J. E. ASTON PRACTICAL CHIMNEY SWEEP".
