light beam
Focused brightness streak
A light beam is a narrow, concentrated ray or shaft of light traveling in a straight line.
Flashlights project light beams; sunlight streaming through a gap in curtains forms a light beam.
The term appears in physics to describe directed light used in experiments or measurements, and in everyday contexts for any visible column of illumination: A light beam cut through the darkness.
