The lighting in the side tunnel is a small ceiling light like an emergency light that you get in buildings when there is a power cut it gives you
enough light to see the sides and ground in front of you , if you look at the video you will see that there is one in the tunnel where the person is
stood taking the photo, thats the sort of light that's in the side tunnel, and it's roughly 12 feet from the camera.
Hope this helps you .
