Light with a
flat perspective
The Putora Bulb redefines the standard form. A flat-top LED filament bulb engineered for architects — available in six finishes, 10,000-hour rated, E27 base.
A flat form.
A deliberate choice.
Every standard bulb has a rounded top. The Putora Bulb doesn't. The flat-top geometry emerged from a collaboration with Swiss architects who needed a bulb that wouldn't compromise the line of a pendant or recessed fixture.
Clear or milky.
You choose the light.
The clear glass exposes the sculptural filament in full — a precision object you want to see. The milky opal finish diffuses light softly, eliminating glare while preserving the flat silhouette. Both in 2700K warm white.
Warm white.
Every evening.
At 2700K, the Putora Bulb produces the same warm, amber-tinged light as a classic incandescent — without the energy cost or short lifespan. Designed for spaces where light is a material, not an afterthought.
Six finishes. One form.
Engineered for
architectural precision
The Putora Bulb's flat-top geometry is no accident. Developed in collaboration with Swiss architects, the form factor is designed to sit flush in recessed fixtures, pendants, and bespoke luminaires where conventional bulb shapes compromise the design intent.
