Ceiling Lamp
The piece
Frosted Glass · Mushroom Dome · Plug-in · No Electrician
A sculptural plug-in table lamp built from two stacked geometric shapes — a wide half-sphere glass dome resting atop a tapered cylindrical glass body that narrows upward like a pencil tip beneath the dome. The geometry is deliberate and architectural, a quiet study in proportion that has earned the silhouette a place in modernist interiors for decades.
Both pieces are formed from opaque blown white glass, so the entire lamp glows softly when lit — direct light from the dome above, diffused glow through the body below. Available in two sizes and four plug standards for use anywhere in the world.

Features
Sculptural Glass Form
Half-sphere dome on a tapered cylindrical body — both blown from opaque white glass.
Direct + Diffused Light
Dome casts direct downlight while the body glows softly from within.
Plug-in & Portable
59" cord with inline switch — no electrician, plugs into any standard outlet.
Material
White Glass
Opaque blown white glass throughout — both the dome and the body share the same material and finish. The glass diffuses the bulbs into a soft, even glow rather than harsh point light. Pairs with any palette — a quiet sculptural element on a console, bedside, or sideboard.

FAQ
Which size suits my space? +
The Small (∅ 25 × H 35 cm) is the typical bedside-lamp size — also suits compact console tables, office desks, and shelving. The Large (∅ 35 × H 50 cm) is a statement piece — better for wider sideboards, living-room consoles, entryway tables, or pairs flanking a sofa. Pick based on the surface depth and the visual weight you want.
Do I need an electrician? +
No — this is a plug-in table lamp. The 59" cord plugs into any standard wall outlet, and an inline switch on the cord controls power. No hardwiring, no junction box, no electrician needed.
Why does it use three bulbs? +
The three-bulb arrangement (one in the body, two in the dome on the Small; equivalent distribution on the Large) is what produces the lamp's signature glow-from-within effect. A single bulb would create a hot spot in the dome; three smaller bulbs distribute the light evenly through the entire glass body. Use low-wattage LEDs (max 5W each) — three small LEDs together are still very gentle on the glass.
Will my plug fit my outlet? +
Pick the plug standard that matches your country at checkout: US (most of North America, Mexico, Japan), UK (United Kingdom, Hong Kong, Singapore, Malaysia), AU (Australia, New Zealand, China, Argentina), or EU (most of continental Europe). The lamp itself is universal voltage (110–240V), so all plug versions are electrically equivalent.
Is it dimmable? +
The lamp itself doesn't dim, but it becomes dimmable when paired with dimmable LED bulbs and a plug-in dimmer module (sold separately). Wall dimmers don't apply to plug-in fixtures.
Care & delivery
Looking after it
Dust with a soft dry cloth. Stone, plated and painted finishes dislike solvents and abrasives, so keep both away from them; glass takes a lint-free cloth and a little glass cleaner. Solid brass is left unlacquered on most pieces and will warm and darken with handling, which is the material behaving as it should rather than a fault. Switch a fixture off and let it cool before cleaning it.
Who makes it
This piece is manufactured for Elio Marchetti by Radilum, our production partner for the collection.
We are a lighting house rather than a factory. We select the pieces, specify the finishes and the stone, and hold the relationship with the maker, and we would rather tell you that plainly than leave it unsaid. Questions about the manufacture of a specific fixture are welcome and we will answer them.
Delivery
Allow 28 to 43 business days from order to arrival, roughly six to nine weeks. Most of the collection is made to order, so that time covers the piece being built in the finish and size you chose, checked, packed and shipped. The same window applies wherever you are.
Shipping is free to Canada, the United States, the United Kingdom and Australia, with no minimum order.
Returns
You have ten days from receiving a piece to have it on its way back to us, under way inside those ten days rather than simply flagged with us on the tenth. Return postage on a change of mind is yours, there is no restocking fee, and the outcome is a refund to your original payment method rather than store credit. Made to order pieces return on the same terms as stock. Contact us before sending anything back.
Damaged or faulty on arrival
Separate from an ordinary return, and a longer window: twenty days from receipt to report it. Tell us before you send anything, keep the packaging until we have answered, and photographs of both the fault and the box help. Where a piece is faulty, damaged in transit or not what you ordered, we cover the return postage.
Installation
Any hardwired fixture should go in with a licensed electrician. Where a piece has particular requirements, a sloped ceiling, a chain that can be shortened, a specific socket, they are listed further up this page.
The collection
Glass
Blown, ribbed, frosted and clear glass, where the diffuser does as much of the work as the frame.
