As far as I’ve seen, ALL lights can go through walls and it’s a matter of light radius. Some weaker candles won’t go through the wall/floor, depending on the house (I had made a very dark, chiaroscuro build in Velothi Reverie and some candles and other lights worked while others didn’t, and a magical portal was definitely out). I have found Mathiisen Manor especially problematic for this — even fires in the fireplace light the other side of the wall and light from crystals, Ayleid chandeliers, the vampire azure chandelier, all go through floors, walls, ceilings; I had to abandon the build idea I’d had in mind.

Unfortunately this is to improve performance. If every light source was to cast a shadow (aka become a projector), it would eat up a lot of GPU cycles, especially in areas where there's a lot of lights.

I mean on PC they're constantly adding new graphical features like DLSS and FSR, so perhaps we'll get raytraced lighting and shadows one day - that would eliminate this problem.

True, I wouldn’t expect every object to cast a shadow, but it would be nice if walls, floors, and structural pieces for instance blocked light. Or special furnishing pieces to block light might be ideal since many players take advantage of light passing through walls to light an area without a visible source, etc.
