In scp animations, the main location was this corridor.

Maybe someone could use it and look for this map, but...it's just a model. Which is lit with 16 light sources, to get good (Exactly what is good, not overly bright) light.

Basically, the point is that you shouldn't try to put all the lighting ‘inside’ the corridor. You either don't have enough space or the light will be bright anyway. And for lighting the whole corridor, several light sources may interfere with each other. Therefore, it is not the worst idea, in my opinion, to place some of the lights outside the model. In this way, the light will shrink in brightness, becoming...rather...moderately soft, without taking up too much space.

As for the light parameters. Almost always I adjust only 3 sliders

-intensity

-horizontalFOV

-verticalFOV

To adjust the ‘radius’ of the glow, as well as the brightness itself. All other sliders, I use mostly when the emphasis is on +- static figure.
