Last evening, Tam and I installed the new backyard "barn light," a $35 gadget with a nice-looking cast-aluminum housing, ceramic (!) mogul-base socket and featuring a 65 Watt CFL bulb that lights up the back yard more brightly than we've had in a long time.
The only functional question left is, will it shut off once the sun comes up? It was dark by the time we finished, so it came on immediately. I should've checked last night with a bright flashlight, but I didn't think of it until after I'd put everything away including the ladder. ETA: Yes, it shut down once the sun was up.
Tam was surprised to find that most of the overhead lights are on the same breaker as the yard light. Like many old houses, Roseholme Cottage (built in1924) probably started out with a fusebox that had four 110V circuits (and possibly one 220V for a range). Main floor lighting on one, basement and attic on another, two left for the baseboard sockets, and welcome to the future, Ma'am. It appears that all of the original sockets were on the shared interior wall that runs lengthwise through the entire house, separating bedrooms and bath from living room, dining room and kitchen; subsequent remodels and installation of larger electrical service (and breaker box) added receptacles on the outside walls and additional inside walls, leaving the original wiring in place. --I need to do something about that, by and by; in the meantime, the old sockets have only a couple of lamps on them and many overhead fixtures have lower-current CFLs.
