In stage lighting, what does CSI stand for?

Explanation:
Compact Source Iodide is the term used for a small, high-output discharge lamp type in theatre lighting. The “compact source” part means the fixture delivers bright light from a smaller housing, which is handy when space is limited. The “iodide” part refers to the lamp chemistry, which influences color rendition and efficiency. This is why it’s the best answer: it directly corresponds to a real lamp designation in stage lighting terminology. Other options don’t fit because they aren’t standard names for a lamp type. They describe either other concepts (like beam characteristics) or terms not used for lighting sources.
