After they are dismounted, you may have to take apart the socket assembly to get at the wires. It's possible that there is what's called an Underwriter's Knot at the base of the socket; this is a knot put in the individual wires that resists them being pulled away from the contacts in the socket. There is also a product known as cable pulling lubricant, which is a foam that comes in a can: if there really is corrosion in there, it may help to squirt some lubricant into that curved tubing section to assist with easing the cable out. If this is beyond your skill set, I am sure a lamp shop can rewire those fixtures if you bring them in.

Thanks. The electrician used the foam (he took apart the socket assembly). He said he couldn’t get the wires through and remounted them. I have not tried it myself yet, just getting my ducks in a row and waiting for the rain to stop before I take them off the wall.

Just a question: did all three lights stop working exactly at the same time, or did they fail one after the other? if they failed all at the same time, the issue might be with the house wiring and not the fixtures themselves, more likely at the mounting box of the working light, or the mounting box of the first non working light. But I suppose the electrician ruled that out first.

Yeah, electrician says the house wiring is fine. There is still one fixture that works, but it is a little more sheltered than the other three (under a deck).

water in water out on exterior lighting, I would probably drill a very small hole in the bottom of the J to stop this from happening again. how old are they, where did you buy them and who is the MFG?

I actually do not know who the manufacturer is. They’re a little more than 5 years old, purchased at a local lighting shop when we built our house. Not sure there would be a warranty at this point. Situation was exacerbated by a gutter that failed and it took months to get someone out to fix it.

I would take it to the lighting shop you purchased it from, they maybe able to repair it or even send it back to vendor for repair. Probably still cheaper than replacing

It’s worth a try! Definitely cheaper than replacing.

Hey all, just wanted to let you know the CLR worked to get the corrosion out of the tubes. It took me a bit to first find replacement sockets and then wait for the weather to dry up a it, but it worked on the first fixture. We are moving on to the other two. Thanks for your help!
