Utilizing fluorescent light tubing available on the commercial market, Dan Flavin created light installations (or “situations” as he preferred to call them) that became icons of Minimalism. Flavin’s wall- and floor-mounted, site-specific fixtures, composed of intersecting and parallel lines of light in conventional colors, flood spaces with their glow. A number of the sculptures feature tubes traversing corners or doorways, or at a right angle to the wall, further engaging the architecture of a room.
