CATHODE

CATHODE is a scientifically inspired pendant luminaire that reinterprets the classic light bulb with a poetic, industrial elegance. The CATHODE features mouth‑blown glass combined with a slim metal structure, producing a silhouette that feels both nostalgic and strikingly contemporary. As a design object, CATHODE evokes the idea of a bulb that never existed—an instrument where the rudiments of electricity meet modern LED technology. Installed singly or in clusters, CATHODE provides focused, warm illumination ideal for dining tables, counters and curated architectural settings.

The blown glass softens and sculpts the light while the metal frame emphasizes the design’s precision and technical character. CATHODE brings narrative and atmosphere to interiors, working equally well in private residences and hospitality projects that seek a distinct, handcrafted aesthetic. Attention to material and finish amplifies the lamp’s presence without overwhelming a space.

In addition to the standard version, CATHODE is offered in an ENDLESS version, extending the concept into alternate configurations. With its balanced blend of emotion and invention, CATHODE demonstrates how a simple, beautifully executed idea can illuminate both form and feeling.
