In depth

Four, because a rectangle is a fixture rather than a lamp. A window, a softbox, a lit panel: a scene with more than a handful of these is a scene that wants them baked into an environment, which is what the prefilter and the loader are for. Raising it is a uniform-array size and an iteration of the loop, exactly as MAX_POINT_LIGHTS is.
