Lite (Light) Electrical (shudder) work

I have to replace a few room lights in the house, now I don't have a problem doing this since 99% of the house lights have wall switches to kill the power. So I bought a few LED room lamps to swap out the older fixtures. The fixtures that require replacement at this time are both upstairs rooms, the top of the stairway, and the bathroom. Sooner of later I will be switching all the lights to LED.

Now, the one light in the entire house which is not on an external switch is directly over the kitchen sink. guess which light had it's chain pull out of the switch socket, yup, that sink light.

I dropped the unit and found that the wires went up into the ceiling, I pulled on it a bit and still saw no splice joints. So, not wanting to simply cut hot wires, I sat and stared at it for a half hour while drinking a coffee. The house was wired by an electrician in 1958/9
and his idea was to link anything and anything that didn't make sense together. So I called Old Young and asked him to bring a meter so we could determine when that circuit was dead. Old Young came last night after work.

He came in with his bag of electrical tools and went right to work, he pulled the wires down further and two wire nuts appeared, he gave me that look that Pancake makes when he wonders if you're daft. He then changed the fixture. 

Since he was there he installed the LED light in the upstairs room which as just painted, this actually became a chore. What should have been a simple loosen the screws, lower the unit, disconnect the wires and reverse the process to install the new unit was not that easy. The original electrical mount box was black, round and looked like it came out of a 1929 Hudson. With 2x4s in the way above the box had been installed only half recessed and was held in place by a big nut in the center and a couple nails in the side.  The new unit is held in place with a threaded rod, so pancake installed the depressed bracket upside down then we cut the threaded tube and cut the plastic collar back on the new fixture, this gave us enough room to thread it in and tighten the unit to secure it flush with the ceiling.

The LED unit for the staircase threw me for a loop, Pancake took it out of the box and handed it to me.

It had, as you can see from the photo above, a regular screw in light bulb section on it, so how do you replace that?

Well it turns out it is easier than I thought, Since we were using an existing fixture we would not need the mount plate.

All you need to do is disconnect the wires from the original lamp and install the new socket.

Once that is done you tuck the wires up inside and screw the new fixture into that socket. 

Insert the mount screws through the slotted sections and tighten. The cover then just rotates on and locks.

Which reminds me, we still need to paint the doors, jams and ceiling at the top of the stairs
