Model 548 by Astep. Light as a modern gesture.

Jan, 2026 • 2 Min. Read — General

Designed in 1951 by Gino Sarfatti, Model 548 encapsulates a way of understanding lighting in which technology is not concealed, but becomes expression. A table lamp that explores balance, reflection and the perception of light with an almost mathematical clarity and, at the same time, a deeply poetic sensibility.

Its structure responds to an essential principle: directing light with precision to create soft, controlled atmospheres. The spotlight projects light onto a reflective screen, generating a balanced combination of reflected and diffused illumination. A subtle interplay that transforms light into architectural matter, capable of accompanying a space without imposing itself.

Balance, reflection and perception.

The large diffusing screen, available in orange, yellow, blue, grey or white methacrylate, is key to this visual dialogue. It not only modulates the light, but also introduces a sophisticated, almost scenographic optical effect that alters the perception of the whole. The white-lacquered aluminium spotlight, the brass tube with polished or dark burnished finish, and the small counterweight, also in brass, form a structure in perfect balance, where every element has a precise function and a clear formal rationale.

In Astep’s re-edition, Model 548 remains faithful to the original design, discreetly incorporating an LED light source and an integrated optical dimmer. Technological innovation is added without altering the initial gesture, respecting the logic and elegance of the project.

The relevance of a modern classic.

Model 548 proves that timeless design does not rely on nostalgia, but on coherence. When form is born from function and detail is resolved with intelligence, the passage of time does not weaken the object, it confirms it. A lamp that remains contemporary because it was conceived with rigour, experimentation and a deep sensitivity to light.

A piece that perfectly embodies Astep’s spirit: recovering icons of modern design and bringing them back to the present with respect, precision and a contemporary outlook.

Responsible design, made to last.

As part of its commitment as a certified B Corp, Astep has reviewed and redesigned each of its pieces to meet more demanding environmental impact standards. This process has involved a thorough re-engineering of the product, aimed at maximising its lifespan and ensuring that every luminaire is fully repairable. A conscious way of understanding design: not as an ephemeral object, but as a lasting presence, conceived to accompany the user over time and reduce the need for replacement.

This website is dedicated to all those people who, in one way or another, have helped this project/dream/desire to begin and take shape.

Special thanks to my wife and my parents for supporting me, to Cristina Escarrà and Alfonso Pérez Rosales for generously sharing with me their experience as agents, to those clients who, in one way or another, have given me wise advice, to the brands that have placed their trust in me, and to Gonzalo, my godfather, who, with his always generous help, and guiding me throughout this process, is largely to blame for the fact that I can boast of being an “entrepreneur”.

Thanks also to Nuria, Rafa and Guillermo, who, to help me in the hard beginnings of any entrepreneurial activity, have opened the doors of their home, let me share with them a bit of their personal lives when I pass through their cities of residence, and give me free accommodation.

Thanks to all!
