A hand holds a Sun Jar Classic by its handle against the setting sun

Sonnenglas Sun Jar

The original. Since 2013.

Often copied. Never matched.

Invented to bring light where there is no electricity. Then it went around the world.

Built in South Africa in 2013 to replace candles and paraffin lamps. Today the Sonnenglas stands on balconies in Berlin, on beaches in Japan and in townships near Johannesburg. Bought millions of times — and still the same jar.

Simple. Clever.

Everything it needs. Nothing it doesn't.

Stainless steel and real glass, no plastic. It stands steady like a lantern — built to last for years.

The Sun Jar Classic from above at an angle: glass, lid with SOMO solar light and switch, wire handle

Magnetic switch

The clever switch on top of the lid. The day/night sensor does the rest.
SOMO solar light module

Solar cells on top, battery and light in one module. Replaceable and removable, it also shines on its own. Charges by sun and via USB-C.
Stainless steel

Screw ring and wire handle in rust-free stainless steel. To carry and to hang.
Soft, warm light

Dimmable up to 100 lumens, warm white (3000 K). Soft, indirect light, bright enough to read by.
Decorate the inside

Shells, flowers, memories: what goes in the jar is up to you.
Real recycled glass

No plastic. Stands steady, even in the wind.

The best moment

When it gets dark, it begins to glow

Lid on, and the day/night sensor takes over: on at dusk, off at dawn. No cable, no socket.

A Sun Jar Classic and a Mini on a rock in the midday sun

By day

By day it catches sun. And looks good doing it.

On the windowsill, the garden table, the rock above the valley. At night, whatever you put inside lights up.

At home

A piece of the sea, on the table.

Your personal light

Make your memories glow

By day a decoration: shells from the last holiday, cones from a walk in the woods, the figure from the children's room.

We ship the Sun Jar empty: the decorations in these pictures are ideas, what goes in the jar is up to you. The exception is the Artisan Edition, crafted by hand by African artists.

And at night

Then they glow

Always the newest generation

Outside, the same jar since 2013. Inside, always the newest.

Buy a Sun Jar today and you get the sixth-generation SOMO: 100 lumens, USB-C, dimmable, IP65 weatherproof. And because it swaps out, after years you replace the module — not the lantern. That is what our upgrade programme is for.

Does it work in other solar systems?

So far the Sonnenglas is approved for our solar system only and tested exclusively with our Sun (Sol, spectral class G2V). Interstellar travellers, please write to info@sonnenglas.net before departure with details of your host star — we will check whether it works there. Photos are very welcome, and so are invitations to the Restaurant at the End of the Universe. And whatever you do: don't forget your towel.
