This is a good photograph by Lance Gerber of the art installation. I feel Lance is drawing on a few different composition techniques to strengthen the subject. There is a story being told, the different moods from the lighting and our human subject is looking into the yellow mood, it reinforces our urge to also want to "go to the light". The eye is drawn to the light because of the rule-of-thirds, lining up the light with the right third and the person with the bottom third. The way light at the end of the hall shines out and mixes with the other lights makes this radial composition.
