Light and Space is a loosely affiliated movement that emerged in Southern California in the 1960s, related to op art, minimalism and geometric abstraction, and influenced by John McLaughlin's spare abstractions. Its real subject is perception itself: artists direct natural light, embed neon and fluorescent tubes in objects, or work with glass, resin and cast acrylic so the viewer's experience of light, volume and scale becomes the work. Materials and fabrication methods were often borrowed from the region's aerospace and engineering industries. The name dates from the 1971 UCLA exhibition 'Transparency, Reflection, Light, Space: Four Artists', and the movement is closely related to the glossy industrial surfaces of Finish/Fetish. Shown at the 1976 Venice Biennale and surveyed in 'Phenomenal: California Light, Space, Surface' (2011), it permanently changed how contemporary art treats atmosphere as an artistic material.

Defining characteristics
Light treated as the primary material: embedded neon, fluorescent tubes or directed natural light
Flawlessly finished industrial surfaces - cast acrylic, resin and glass with high-gloss polish
Perceptual ambiguity: edges dissolve, volumes seem to float, shift or recede as the viewer moves
Works conditioned by their surroundings, often altering the gallery space itself
Subtle gradations of transparency and color instead of depicted imagery
Reduced near-abstract forms - columns, cubes, orbs, scrims - that frame the act of seeing
