Morphology
gas-discharge + lamp
The compound is compositionally built: 'gas' + 'discharge' describes the mechanism and 'lamp' denotes a light source, so the overall meaning (a lamp that produces light via a gas discharge) is directly inferable from the parts. Although slightly technical, this formation follows common modifier+noun patterns and would be understandable to a B1 learner who knows the constituent words.
Etymology
Gas-discharge lamp comes from how the gas inside a glass tube lights up when an electric discharge, a small spark or flow of electricity, jumps between metal parts, so the word names a lamp that makes light this way.
