The arm swings. That is the whole trick, and it is a good one. Take hold of the shade, move it, and the light goes where you are instead of where the lamp happens to stand. Fifty-six inches of antique brass with a joint at the top, and the reason someone will take this home is that it solves a problem the ceiling fixture never has.

A swing arm pivots at the column and again at the shade, so the light reaches out over a chair, a lap, a page, then folds back out of the way when you are done. Every modern reading lamp is still copying this mechanism. It was worked out long before anyone thought to call it task lighting.

The column is fluted brass, slim and darkened with age, rising from a heavy round base cast with a ring of laurel leaves. The brass has gone warm and uneven the way brass does, bright on the high spots and nearly bronze down in the hollows. A small acorn finial caps the whole thing off.

The shade is a bell shape in soft cream with a gently scalloped hem, and the pull chain ends in a proper tassel, the kind of detail nobody bothers with anymore. You will pull it more often than you strictly need to.

Set it behind a wingback or at the corner of a sofa and swing the arm out over the seat. At fifty-six inches the light arrives at shoulder height, which is exactly where a reader wants it and nowhere near your eyes.

Come see it in person at Pollyanna’s Antiques in downtown Mt. Clemens, open Wednesday, Friday, and Saturday from 10 to 4. Swing the arm yourself. That is the fun part.
