Hourglass-like Lamp Changes Lighting When You Flip It Upside Down

Most table lamps quietly disappear into the background, doing their job without much thought. There is the usual formula: a base, a stem, a shade, and how they become part of the furniture, you stop noticing. JAL from Barcelona studio Som by Mos leans into that ordinariness on purpose, then uses a very small twist to make the everyday feel a bit more deliberate and less forgettable.

JAL is a table lamp built around two glass cones joined tip to tip, like a clear hourglass. The bulb sits inside this double cone so it appears to float in the air, and the whole piece is available in transparent or frosted glass. The only other visible element is the cable, which comes in different colors and quietly sets the tone.

Placing JAL with the bulb facing upward on a sideboard, it behaves like a familiar table lamp, throwing light onto the wall and ceiling. Flip it so the bulb points downward, and it turns into more of a glowing object that pools light on the surface below. That simple rotation changes how you use the lamp, from reading companion to ambient accent.

The clear-glass version makes the bulb and its reflections the main event, better suited to a living room corner or a shelf where you want a bit of sparkle. The frosted version softens everything, turning the hourglass into a diffuse glow that feels more at home on a bedside table or a quiet desk. The form stays the same, but the way it holds light shifts with the finish.

Som by Mos offers a selection of cable colors, so the one strong line cutting through the glass can either disappear or become a graphic detail. A neutral cable lets the lamp fade into a minimal setup, while a bolder color makes it feel more playful. Those small decisions, orientation, glass type, cable, are how the lamp becomes “whatever you want it to be.”

Som by Mos talks about objects that are not just used but experienced and interpreted. JAL fits that idea because it does not force a single reading. It is a lamp you can turn, soften, or sharpen with tiny choices, and over time, those choices are what give it personality. Loud lighting fills rooms with fixtures demanding attention, but a quiet hourglass of glass and light can feel like exactly the right kind of “just another lamp.”
