Light art is a form of contemporary art in which light itself is the primary medium. Artists use artificial or natural light to create works ranging from sculptures and wall pieces to immersive environments and large-scale installations. These works often transform spaces and invite viewers to experience light as both material and idea.

While artists have long been fascinated by light, light art as a distinct form began to emerge in the early 20th century. Pioneers such as László Moholy-Nagy, who experimented with light projections and kinetic sculptures, and Naum Gabo, who incorporated illuminated elements into his constructions, laid the groundwork for the medium. In the 1960s and 1970s, artists like Dan Flavin, with his fluorescent tube installations, and Keith Sonnier, using neon and industrial materials, pushed light into the center of contemporary practice. Since then, advances in technology – from LEDs to digital projection – have expanded the possibilities, establishing light art as a vital and innovative field today.

Renowned light artists include Dan Flavin, known for his fluorescent tube installations; James Turrell, who uses light and space to create meditative environments; and Olafur Eliasson, whose large-scale installations often combine natural phenomena with artificial light. Other important figures include Bruce Nauman, Jenny Holzer, and Keith Sonnier, each of whom has explored light as a powerful artistic medium.
