Brief
Permanent lighting for a converted granary housing 18th-century shipping records. The archive needed lux levels below 50 to protect ink, yet the reading room had to feel clear, warm, and usable at 4pm in January, when daylight falls away and the harbour becomes a dark plane outside.
Approach
The first decision was to treat the records as the brightest surfaces in the room without making them objectively bright. We mapped each reading table, shelf face, and circulation line separately, then built a low-output system around layered contrast rather than general illumination. The conservation brief set a hard ceiling of 50 lux at document level, so the working range became 32 to 46 lux with tight dimming tolerances. Vertical timber surfaces were lifted slightly above the tables to make the room feel inhabited, while the ceiling stayed quiet. A concealed linear system washes the old grain chutes from below, giving visitors a sense of volume without sending light onto the collection. At the perimeter, small shielded optics pick out catalogue numbers and handrails. The control scenes respond to calendar time, not occupancy alone, because the winter afternoon condition was the real problem. At 15:30 the room warms by 150K and the wall balance rises by eight percent. At closing, all collection surfaces step down before staff lighting comes up. Every source is accessible from service walkways installed by the architect, so maintenance never requires equipment near open records. The result is not dimness. It is a room where the eye has enough information to settle.
