The best loft lighting in a converted mill, warehouse or factory is the light the building was designed around: spun-metal RLM shades hung on stems or goosenecks from the structure, scaled to the ceiling height and fitted with modern LED. Pick the shade profile that matches the building's era, then set the drop, color temperature and finish for how each floor is used now.

Walk into one of these buildings before the work starts. Morning comes through a wall of steel-sash windows, dust hangs in the air, and the old conduit still runs along the timber beams to a row of empty outlet boxes. Those boxes once held dome and radial shades, the working luminaire of American industry. Lighting the building's first life means putting that shape back, not hiding the ceiling behind a grid of troffers.

Bock configures and builds each shade to order from our headquarters in Twinsburg, Ohio. Diameter, mounting, color and LED module are chosen per project, so one order can light a hundred-plus loft units, a food hall and the loading-dock facade in the same finish.

A conversion rarely has one use. The same building might hold apartments, offices, a market hall and retail. Each needs a different answer under the same ceiling.

Residential lofts

Ceilings of 12 to 16 ft and exposed brick call for mid-size shades hung low enough to feel domestic. A 12 or 14 in. Step Neck Dome on a stem over a kitchen island, with the bottom of the shade about 30 to 36 in. above the counter, reads as original and gives good task light. Specify 2700 to 3000 K and a 90 CRI module so brick and wood look warm. For bare-bulb character, Leluce Sockets are triac dimmable with supported lamps and UL listed for wet locations.

Loft offices

Open floors with 14 to 20 ft ceilings need more light and more even coverage. Use 16 to 20 in. domes or the fluted Radial Wave in regular rows, dropped on stems to a common height so the rows line up under beams and sprinkler mains. Use 3000 to 3500 K for work areas.

Market halls and food halls

The tallest volumes take the biggest shades. The Beretto is spun aluminum in sizes from 15 to 60 in. and is cULus listed for damp locations, so keep it indoors.

Loading docks, facades and courtyards

Outdoors, use cULus wet-listed shades on goosenecks, or the VW vaportight wall mount over doors and stair towers.

If the project uses the 20% federal historic rehabilitation tax credit, the State Historic Preservation Office (SHPO) and the National Park Service review the work against the Secretary of the Interior's Standards for Rehabilitation. Lighting is part of that review because it changes how the historic interior reads.

Compatible, but not falsely historic

The Standards discourage adding features that create a false sense of history, and ask that new work be compatible with the old but distinguishable from it. In an industrial building, a plain spun-metal shade in a period profile, fitted with a modern LED module, usually meets both tests. It suits the space and doesn't pretend to be a 1920s artifact. Ornate reproduction fixtures that the building never had are the harder sell.

What to bring to the review

1. Photos of any original fixtures, outlet boxes or conduit runs that remain.
2. The spec sheet for each proposed fixture, with the profile and finish marked.
3. A reflected ceiling plan showing that fixtures hang from the exposed structure rather than a new dropped ceiling.

Some state credit programs treat light fixtures as non-qualified costs, so check with your consultant before you count them.

Matching what is already there

Salvaged shades can be matched by diameter, profile and neck thread. Bock shades top-mount on 3/4 in. NPT as standard, with 1/2 in. available. Match the original enamel color with custom powder coat, or choose galvanized for a bare-metal look. Order the whole building's quantity in one run so the color stays consistent from phase one to phase three.
