I’d also suggest putting a semi-Transparent Neon Part on the floor and the opposite wall to make it appear the light is hitting those surfaces.
Although why not just put an actual window opening there, with SunRays on? You could get the same effect by adding your Anchored Part for the lighting effect, but you’d also get the added effect of the player being lit up and their shadow casting onto the wall and floor when they walk down the hallway.
