Drum or Tapered? How the Shade Shape Changes a Room

July 26, 2026Lumé Maison

Two lamps can have the same bulb, the same brightness and the same warm colour temperature, and still light a room completely differently. The variable most people never consider is the shape of the shade. It is not decoration. The silhouette decides where the light physically goes.

A drum shade throws light up and down

A drum, or cylinder, shade has straight vertical sides. The opening at the top and the opening at the bottom are the same width, so light escapes in two even columns: one up onto the ceiling, one down onto the surface. Very little escapes sideways, because the fabric wall is vertical.

The result is a tidy, contained pool of light and a soft wash on the ceiling. It reads modern and architectural, and it is the better choice on a small nightstand or a narrow shelf, because the footprint stays the same from top to bottom and the light does not spill into your eyes when you are lying down.

A tapered shade throws light outward

A tapered shade, sometimes called an empire shade, is narrow at the top and flares wider at the bottom. That angle matters: the sloping fabric pushes light outward as well as down, so it lights the table, the wall behind it, and part of the room. It fills space rather than concentrating it.

This is the classic table-lamp silhouette for a reason. It is the friendlier shape in a living room, a hallway or a dark corner, because one lamp covers more of the room. The trade-off is that it needs a bit more surface area to sit on, and the wider bottom edge means more light reaches your eye-line.

Which one for which job

• 01Bedside reading, small nightstand, contained light: drum.
• 02Filling a dark corner or lighting a wall as well as a table: tapered.
• 03Modern, minimal, architectural rooms: drum.
• 04Warm, traditional, layered rooms: tapered.
• 05Very limited surface space: drum, every time.

You can use both

These are not competing options so much as different tools. A well-lit room usually wants at least three points of light, and mixing silhouettes is part of what stops a room looking like a showroom. A tapered lamp on the console filling the room, a drum lamp on the nightstand for reading, and the ceiling light off. We wrote about that layering approach in how to create ambient lighting at home.

The two shapes, from our own collection.

Siena

$44

Tela

$49

From the Maison: Siena is the tapered one, a flared linen or jute shade on a turned bamboo base for rooms that need filling. Tela is the drum, a straight woven cylinder on turned oak, sized for a nightstand that is already crowded. Both are cordless, rechargeable and dim to a candle, so the only real decision is which direction you want the light to go.
