Morphology

compact + fluorescent + light

The meaning is directly built from the constituents: 'compact' = small, 'fluorescent' = producing light by fluorescence, and 'light' = a lamp/bulb, so the phrase denotes a small fluorescent lamp. This adjective+noun composition follows ordinary English compounding patterns and is cross-linguistically transparent, so a B1 learner who knows the component words should understand it.

Etymology

Compact fluorescent light comes from making a long fluorescent tube small and compact by bending it so the lamp can 'replace' an ordinary bulb. Because of this shape, it uses less electricity and lasts longer, so the term now means a small, 'energy-efficient' light bulb.
