Adding light fixture over bathroom sink with plumbing vent obstruction
Hi- I’m redoing a small bathroom and I’d like to add a light over the bathroom sink which did not exist previously. Running the electrical won’t be an issue since I’ve removed the bottom half of the drywall. However, there apparently is a plumbing vent running right up the middle of the wall so I won’t be able to install a full size electrical box. I assume I can use some sort of shallow box? I won’t be able to attach it to a stud unless I remove the drywall.
You will put on a horizontal board just like you have in the photo. Drill a 1" hole in that board for the wire to go through, and yes, they make shallow metal boxes. Put the wire through a cable clamp, put the cable clamp through the shallow round metal box, put the cable clamp nut on the inside of the box and tighten it, then screw the box onto the board.
Obviously you will need to remove and patch the drywall... the board goes up first and you need to choose which knockout to remove from your box and mark where you are going to drill the hole based on where the light is going to be.
With all those holes in that horizontal 2x6 I hope no one put a screw into your vent pipe. It should have had a metal "no nail" plate protecting it.
What are you using for a fixture ?
Many bathroom wall fixtures have a wiring pan built in and don't require any box.
There are many strip lights from 3-7 bulbs. They have a metal pan with multiple knockout locations on the back. You bring the wire out of the wall, thru the connector in the pan which is directly into the fixture. No box required.
And if you get a wall mounted led medicine cabinet, it may require an outlet above. Nowadays many of them come with transformers and a cord. So figure out what you are putting there because there are many ways to wire it depending on the light.
Exterior porch light.
incandescent.
Motion sensor.
Dusk to dawn.
has an override feature so you can turn it on in daylight or leave it on full time.
I came home, light started to come on, then died.
replaced blub. Used override feature to turn it on with the light switch in daylight. Started to come on, then died.
Checked both bulbs in a different light, both dead.
Fixture is old, i dont mind assuming it is the fixture and replace it, but i wanted to check here and see if it could be something else that i should check first.
Dont want to fry a new fixture.
If it could be in the house,i have a meter and i can check voltage, but i dont know where to check because i cant think of anything that would cause a surge ,or short, without tripping the breaker.
Thanks.

I have 5 old CFL lamps that are being replaced with LED recessed lamps.
I took one lamp out and found a ballast. Cut out the ballast (see photos) and wired the white/black wires direct to the LED lamp to a switch and worked perfect.
Then the problem:
3 other lamps have NO ballasts but has red/blue wiring in a junction box.
Using the white/black wires, I figured they were switched as well.
Nope - won't power up.
Why ?
The old CF lamps used to power up fine which tells me the wiring is intact.
Are the other CF lamps - without ballasts, getting their power from a single ballast somewhere else??
