For obvious reasons I didn’t like the stock fixtures in my bedroom:
Or my bathroom:
Because crappy fixtures take all the swank out of X10 dimmers.
We can see there was some buggery in here to get the bathroom fan running in series with the light (which I fixed the other day). The box is also being used as a junction box for a run of Romex I’m not clear on the purpose of. That’s fine, everything is safely capped and I don’t feel like being a hero today.
Most fixtures and chandeliers have a bracket which is installed in the electrical box. Once it is loosely secured pull the leads from the new lamp through the hole in the middle (which I didn’t do here, they run flush along the top anyway). Use the ground wire to secure the lamp to the box/bracket since it needs to come into contact with the box anyway, now you are free to use both hands to connect the hot and neutral.
Fixtures that hold a diffuser from the bottom use a standard thread and bolt size.
Be careful not to tighten the nut too tightly, an over-tightened glass fixture will explode at random. Finger tight is too tight.
The box in the bedroom is much tidier, despite missing a screw.
Now my ceilings don’t looks so much like shit ^.^
