Morphology
electric-discharge + lamp
The phrase is directly compositional: a lamp described by the mechanism 'electric discharge' clearly denotes a lamp that produces light by an electric discharge. This is a literal, technical modifier pattern (X lamp) that is cross-linguistically common, so a B1 learner who knows the constituents would be able to infer the meaning.
Etymology
Electric-discharge lamp — the name comes from how the lamp makes light: a small electric discharge, like a tiny lightning bolt, jumps between metal ends inside a glass tube to produce light. So the name simply means a lamp that makes light by an 'electric discharge'.
