1917, burning church scene cinematography

I am a senior in high school who is currently writing a paper on how lighting is one of the main components of cinematography. I have been researching more on your collaboration with Sam Mendes on ‘1917.’ Specifically one scene that piques my interest is the flare and burning church scene. In my paper, I am writing about two areas of lighting, natural and artificial. For artificial, HMI, LED, tungsten, and fluorescent lights have been mainly mentioned. I watched a video where you briefly mention the incorporation of dino lights for the burning church. Were there more scenes where any sort of artificial light was used? What is the process of choosing what kind of source of light to use?

Thanks!
