Stuberlighting · Ribbed Alabaster Wall Light No. 171
Costa
Ribbed Alabaster Wall Light
Carved from genuine alabaster with an elegant ribbed face, the Costa lets light filter through real stone into a soft, sculptural glow. Choose from three heights — a compact accent to a tall statement — each one uniquely veined by nature.

The Costa is about one thing done well: a slim column of real alabaster with a ribbed, fluted face. The ribbing isn't just decorative — it catches and deepens the way light moves through the stone, so the glow reads as sculptural rather than flat. Because it's genuine alabaster and not resin, it has real weight, a cool touch, and a translucency that only natural stone produces.
It comes in three heights so you can scale it to the wall — a small accent by a bed, or a tall column that anchors a stairwell.

One of a Kind — Read This First
Real stone, so no two are alike — and a milky-white piece is not a flaw.
Alabaster patterns range from pure milky-white to dramatic grey or amber veining. A mostly white piece is actually a sign of high-purity stone, not a defect — and the veining forms naturally, so it can't be controlled or matched to a photo. That's exactly what makes each Costa unique, and why the exact grain you receive will differ from the images.
If your project needs a specific look — more veining, or a purer white — reach out before ordering and we'll do our best to match your preference. We'd rather set the right expectation up front.
Two Light Versions
Warm, or warm and dimmable.
Warm Light
A fixed warm glow
Ships in warm white (3000K) by default — a cozy tone that suits the stone. Runs on a standard wall switch (not included). The simplest option.
Triac Dimmable Warm Light
Adjust the brightness
The dimmable version needs its driver placed outside the canopy, and pairs with a Triac dimmer switch for smooth, flicker-free control. Choose this version at checkout.
Default is 3000K warm white. Neutral (4000K) or cool (6000K) can be arranged on request — contact us before ordering.
Before You Install
The honest details.
J-box coverage — know before you buy
The base is about 3.9" wide, while standard US & Canadian junction boxes (J-boxes) are typically 4" wide — so the fixture may not fully cover the box. We include a complimentary 12cm backplate to cover any exposed gap. It's entirely optional: leave it off for the clean, flush look shown in most photos, or use it if your J-box would otherwise peek out.
Integrated LED
Uses a built-in integrated LED — a clean, self-contained fixture with no bulbs to buy or swap. The trade-off is that the LED module isn't user-replaceable; we state this plainly.
Wiring & placement
Hardwired wall fixture on a standard switch (AC 110–240V); a licensed electrician is recommended. Rated IP20 for indoor use — not waterproof, so keep it out of wet or steamy areas.

Questions
Answered plainly.
Is this real alabaster or resin?+
Real, genuine alabaster stone — not resin. That gives it premium weight, a cool touch, and a translucency only natural stone produces. The ribbed face is carved to bring out the stone's depth when lit.
My piece looks mostly white with no veining — is that a defect?+
No — a mostly milky-white piece indicates high-purity alabaster. Veining is natural and can't be controlled, and patterns range from pure white to grey or amber. If you need a specific look, contact us before ordering.
Will it cover my J-box?+
The base is 3.9" wide and standard US/CA J-boxes are ~4", so it may not fully cover the box. A complimentary 12cm backplate is included to hide any gap — it's optional if you prefer the flush look.
What's needed for the dimmable version?+
The dimmable driver must be placed outside the canopy, and we recommend pairing it with a Triac dimmer switch for smooth, flicker-free brightness. Choose the Triac dimmable version at checkout.
Which size should I choose?+
The small (H11.8") suits a bedside or tight wall; the medium (H17.7") is the versatile middle for most walls; the large (H23.6") is a tall statement for a stairwell or feature wall. Tap the size images above to see each to scale.
From The Atelier
“The ribbing is the whole point. It gives the stone a rhythm, and it gives the light somewhere to go — so a simple column of alabaster reads as something carved, not cast. We offer three heights and let the stone decide the rest. No two are alike.”
