Morphology

energy-saving + light + bulb

The adjective 'energy-saving' is transparently built from 'energy' + 'saving' meaning 'reducing or using less energy', and 'light bulb' is a literal noun phrase for a lamp; together they yield 'a bulb that uses less energy'. This straightforward adjective+noun composition is cross-linguistically common, so a B1 learner who knows the constituent words can reliably infer the MWE's meaning.

Etymology

Energy-saving light bulb comes from the idea of a light bulb that saves energy. So the name means a bulb that 'uses less electricity' than older bulbs.
