Antique Bridge Lamps: What They Are and What to Check

What an antique bridge lamp is and what to check before you buy one: the swing arm, a steady base, the socket, and whether it takes a glass or fabric shade.

An antique bridge lamp is a floor lamp whose shade hangs from an arm reaching sideways off the top of the stem, so the light can swing over a chair or table. Before buying one, check that the arm swivels and holds its position, the weighted base stands steady, the socket works, and the shade fits its holder.

What is a bridge lamp?

Dictionary.com defines a bridge lamp as “a floor lamp, especially one having the light source on an arm so hinged as to be horizontally adjustable.” It labels the term an Americanism and dates it from 1925 to 1930. The arm is the point of the design: it lets the stem stand beside a reading chair while the shade hangs over the page.

Antique Lamp Supply, a supplier of replacement lamp parts, calls that arm the bridge and says “Bridges can be made of brass or iron.” The same source notes that bridge lamps take either a glass or a fabric shade, each held a different way. If a listing does not say which metal a lamp is, ask the seller to try a magnet: the Canadian Conservation Institute notes that iron is “almost always magnetic,” while brass is not, though brass-plated iron will still attract one.

Other deco floor lamps, such as torchieres that light the ceiling, are compared in the art deco table and floor lamp guide.

What should you check before buying an antique bridge lamp?

Ask for photos of each of these if the listing does not show them:

The arm swivel. The arm should turn smoothly and stay where you set it. A joint that droops may only need tightening; a cracked or bent arm is a bigger repair.
The base. A bridge lamp carries its shade off to one side, so the base has to be heavy enough to keep it upright. Ask whether the lamp stands steady with the arm turned fully out, and look for cracks or a loose stem.
The socket. Look for a missing switch key, a cracked shell or a socket that turns loosely on the arm. Sockets can be replaced, but the new one has to suit the shade fitting.
The shade fit. Check whether the lamp is set up for a glass or a fabric shade, and whether the shade with it actually fits.
The cord and wiring. An original cloth-covered cord should be replaced, and the socket checked, before the lamp is used; the rewiring guide covers the parts. The CPSC warns that “A frayed or cracked cord could cause a shock or fire,” and adds: “The simple act of removing electrical cords from under rugs could help prevent many house fires.” Run a floor lamp’s long cord along the wall, not under a rug.

Glass or fabric shade: how does each one attach?

Parts suppliers such as Antique Lamp Supply list glass shades as fitting “with a 2 1/4 shade holder,” and fabric shades as connecting “to the socket with an UNO thread shell on the socket.” A lamp set up for one kind may need a new part before it takes the other.

For a glass shade, measure the neck that sits in the holder and look for chips or cracks there; a replacement has to match the neck size before the style matters. For a fabric shade, the ring threads onto the socket, so check it for splits, scorch marks and looseness, then match the ring before choosing a size and shape. If a lamp comes without a shade, photograph the holder or socket before you shop so you buy the right fitting.

What shade materials suit an early bridge lamp?

Museum lamps from the same decades show two shade materials that suit a bridge lamp. The Met’s copper lamp by Dirk Van Erp, dated about 1912 to 1915, has a “mica and copper shade.” The Minneapolis Institute of Art holds a lamp of about 1933, attributed to William Lescaze, made of chrome plate and parchment. Neither is a bridge lamp. Both show the shade materials of the years when bridge lamps were popular.

Mica and parchment are both fragile with age. On an old shade, look for splits along the frame, flaking and darkened patches above the bulb. A sound replacement in the right fitting is often the practical choice for a lamp you plan to use every day; sizes, shapes and fitters for fabric and parchment shades are in the vintage lamp shade guide.

How do you look after a brass bridge lamp?

Brass bridge lamps often arrive dull or spotted. Start with the gentlest cleaning method and check for lacquer before using any polish. The brass cleaning guide sets out the steps. On an iron lamp, keep water away from the joints and treat any rust spot early so the arm keeps turning freely.

Frequently asked questions

What is a bridge lamp?

A floor lamp whose light hangs from an arm off the top of the stem. Dictionary.com defines it as a floor lamp, especially one with the light source on an arm hinged so it can be adjusted horizontally, and dates the American term to 1925 to 1930.

Is a bridge lamp the same as a torchiere?

No. A torchiere throws light upward from a bowl at the top of its stem. A bridge lamp hangs its shade from a sideways arm, so the light falls down beside or over a chair.

Can I put a fabric shade on a bridge lamp made for a glass shade?

Sometimes. Lamp parts suppliers such as Antique Lamp Supply fit glass shades to a 2 1/4 inch shade holder and fabric shades to an UNO thread shell on the socket. A lamp shop can tell you whether a socket change will let your lamp take the other kind.

Should an antique bridge lamp be rewired?

Yes, if it still has its old cord. The CPSC warns that a frayed or cracked cord could cause a shock or fire, and a floor lamp's long cord is often walked on or tucked under a rug.

Where can I find a replacement shade for a bridge lamp?

Measure the fitting first: the neck of a glass shade or the ring of a fabric one. Single shades are sold separately, often listed as a bridge lamp shade.
