Large metal-stud chandeliers. Outdoor fixtures, moved inside, run with bulbs they were never built for. Specific bulb-and-fitting pairings, chosen deliberately, not just whatever fit. At the Monument, one section couldn't take conduit in the walls, so the wiring went outside instead: custom-coloured flexible electrical pipe, industrial boxes and switches, tube lights, run in patterns across the wall. A limitation, turned into the feature.
