How to install ceiling light fixtures at the intersection of a beam and a wall

Question

I recently moved into an apartment in Austria, where you're responsible for installing all light fixtures yourself (tenant/landlord laws are very interesting here). Most of the wiring is straightforward, centered in the middle of the room with no excess cables. However, two (A & B) are positioned in tight corners against a wooden beam, and some have protruding plastic pipe encasing them. The last one (C) has an excess length of cable that inspires fear.

My question is, how do we install fixtures here?
For A & B, do fixtures even exist that can be positioned flush against a corner? Are we meant to cut open the ceiling and re-route the wiring into a different position? For C, my husband suggests we either shove the majority of the cable back up into the ceiling, or cut off the excess and reattach the junction boxes. These after I naysayed his idea to keep the excess hanging out of the wall like the world's ugliest pendant light.

All ideas appreciated!!

A - upstairs hallway

B - bedroom

C - living room

Answer 1

For the first two (hallway & bedroom) it looks like you can install any sort of fixture you'd like.

• It's hard to tell from the perspective in the pictures, but mount an up-light on top of the beams for a non-direct light reflecting off the ceiling.
• Mount a sconce on the side of the beam that can direct light out/down.
• Mount a "ceiling" type fixture on the bottom of the beam.

For the third picture, well, yeah, that's a lot of extra wire! Double check with the landlord about that one - maybe there's a reason for it. If not, cut it off so there is ~12" (300mm) of cable, mount your ceiling fixture of choice, and push the extra wire up into the ceiling.
