Oh, sure. I didn't mean the lighting was on the same fuse as the power 
outlets.

Agreed.

>which daisy-chains from each light fitting

Yeah, but all the lights are on one fuse in the house, so if one bulb goes 
errant, it takes out the whole house lighting. I'm used to having at least 
two, and often three lighting fuses in one house.
