It seems there's a lot of thought and nuance to the question of how to light a performance hall. Ancient Grecian theaters were built to ensure natural sunlight would hit the actors during performances, and much later, in the Baroque era, chandeliers became the prominent source of lighting. It seems this is still the case in many theaters (though they are no longer made up of candles!), with the example in the image being a more sophisticated, modernized example.
