Morphology
The meaning 'lightning that appears as a broad, diffuse flash' is directly and transparently built from 'sheet' (a thin, wide layer) + 'lightning' — the compound describes lightning that looks like a sheet. This is a straightforward visual/compositional metaphor following normal noun–noun compounding, so a B1 learner who knows the constituents would readily infer the meaning.
Etymology
The noun sheet lightning comes from the way distant lightning lights up clouds like a big white sheet: you see a wide, soft flash instead of sharp bolts. So, the phrase refers to lightning that looks like a 'broad, spread-out flash' across the sky.
