Seven weights. Not one switch.
Three spheres combine into seven weights. Tap one to see the light it makes.
See it on your table
No pairing, no firmware, no account. It has been ready since the moment you plugged it in.
A sheet of Lycra®, stretched drum-tight over borosilicate glass.
You set a sphere down. The fabric sinks. Light pools in the crater.
A load cell in the base measures the load — in grams, not in steps.
More weight, brighter and cooler. Less weight, softer and warmer.
16″ across, 18″ tall. It reads as furniture, not as a gadget. See it on yours before it ships — the visualizer is in the buy box above.
3,000 lumens. 50,000 hours. Nothing to replace.
Every lamp in your house asks the same thing of you: find the switch, press it, get the same light you got yesterday.
This one asks you to choose a weight.
A small sphere and the room goes to candlelight. All three and it turns into daylight. Nothing on the surface and it rests — a bowl of glass, waiting.
The light stops being a setting. It becomes a gesture.

It wins by having less, not more.
Including the honest four-star one about size.
Nobody walks past it
Every single person who comes over touches it. My father-in-law spent ten minutes putting spheres on and taking them off.
Verified buyer
I bought it as decor. It’s my main light.
3,000 lumens is not a joke. All three spheres and it lights the whole dining room.
Verified buyer
The 0.3 sphere is why it lives bedside
That amber is warmer than any bulb I’ve owned. I read by it and fall asleep faster.
Verified buyer
Arrived in a crate with foam cut to shape
I was nervous about glass this size. Not a scratch on it.
Verified buyer
My four-year-old figured it out before I did
No instructions needed. She stacks them and watches the room change.
Verified buyer
It’s bigger than I pictured — measure your surface
On my console it hangs over the edge a little. On the sideboard it’s perfect. Four stars only because I had to move it.
Verified buyer
No app is the feature
I’ve thrown out two connected lamps that stopped talking to their servers. This one just works.
Verified buyer
The crater of light is what photos don’t get
It moves depending on where you set the sphere down. I keep rearranging it.
Verified buyer
Gave it for a wedding. It out-shined the whole table.
Now I have to buy my own.
Verified buyer
Six months in
Still zero flicker, still the same warm floor at 0.3 kg.
Verified buyer
Foam cut to the shape of the glass. The spheres wrapped one by one. A dedicated fragile-goods lane, not a parcel belt.
And if it still arrives broken: we replace it or refund it. Ours to solve, not yours to prove.
Borosilicate is the same glass family used in laboratory glassware — thick-walled, and unbothered by heat. It travels crated, insured, door to door.
More quiet light from HAVN.
Yes. It ships bivolt with the correct plug for your address. Plug it in and it’s on.
It travels in a foam-molded crate on a dedicated fragile-goods lane, and the glass is borosilicate — thick-walled, the same family used in laboratory glassware. If it still arrives damaged, send us a photo and we replace it or refund you. No return shipping, no inspection process.
Three: 0.3 kg, 0.7 kg and 1.3 kg, in frosted borosilicate, with a PaperStone® tray to rest them on. Combined, they give you seven distinct weights.
No. The membrane is engineered around the three spheres — their weight, and their smooth, rounded contact. Keys, phones and anything with an edge can tear it.
3,000 lumens at full weight. That is a primary light source for a dining room, not an accent. At 0.3 kg it drops to an 1800K glow you can sleep next to.
16″ in diameter and 18″ tall — closer to a floor-lamp head than to a desk lamp. Use the visualizer in the buy box against your own surface before ordering.
A dry microfiber cloth, wiped flat. No solvents, no pressure, and never with a sphere resting on it.
33W at full brightness — less than a single old incandescent bulb, for a light that fills a room. The LED is rated at 50,000 hours, so there is nothing to replace.
Two years on the lamp and the electronics, and 30 days to change your mind for any reason at all.
