Material Detail Click to enlarge
Three-Layer Construction

The Detail Is Around the Rim

Costa stays simple from across the room. Up close, three distinct surfaces give the low-profile form more depth.

01 Exterior

Ribbed Metal

Vertical fluting creates shadow and texture around the outside edge.

02 Interior

Warm Wood-Grain Finish

A warmer inner ring softens the contrast of the black or white exterior.

03 Center

Frosted Acrylic Diffuser

The broad diffuser spreads the integrated LED into more even ambient light.

Material clarity: the warm interior is a wood-grain finish applied over the metal structure. It is not solid or natural wood.
Finish Selection

Black or White?

Both versions keep the same warm wood-grain interior. Choose the exterior by how much contrast you want at ceiling level.

Matte Black Stronger rib definition and more graphic contrast.
Matte White Softer ceiling presence with a lighter overall profile.

Frequently Asked Questions

Good to Know

Is the interior made of real wood? +

No. The warm inner surface is a wood-grain finish applied over the metal structure. It provides the visual warmth of wood without being a solid-wood component.

Is the LED included? +

Yes. Costa uses an integrated LED, so no separate bulb is required.

How bright is it? +

The fixture uses approximately 24W and produces around 2400 lumens. The frosted acrylic diffuser spreads the light more evenly across the room.

Is Costa dimmable? +

The standard Warm Light version is intended for regular On / Off control. If you need brightness adjustment, choose the TRIAC-dimmable version and pair it with a compatible TRIAC wall dimmer.

Black or White — which should I choose? +

Black creates stronger contrast and makes the ribbed exterior more noticeable. White has a quieter visual relationship with most ceilings. Both use the same warm wood-grain interior.

Does it need professional installation? +

Costa is a hardwired ceiling fixture. Installation by a qualified electrician is recommended.
