C. F. Otto Müller ceiling lamp

This ceiling lamp, model Megaphos, was designed by C.F. Otto Müller and produced by Sistrah – Licht GmbH in Germany in 1932. It is an early example of functionalist lighting design, engineered to optimize light distribution through a sophisticated multi-layered glass system.

The lamp features a nickel-plated metal frame with a central rod connecting the ceiling canopy to the shade assembly. The main shade is crafted from opaline glass with a smooth, domed form that facilitates even light diffusion. Beneath this primary shade, a series of stepped glass elements further refine the light’s direction and soften its intensity. This layered glass construction reflects Müller’s focus on glare-free illumination, a hallmark of his technical lighting solutions. The glass assembly is framed by a metal ring with a patinated finish, providing structural stability while contributing an understated industrial elegance.

C.F. Otto Müller was a German lighting designer known for his scientific and technical approach to illumination. His Sistrah lighting system utilized precise optical calculations to maximize lighting efficiency and minimize glare, making his fixtures well-suited for professional environments such as offices and laboratories during the early 20th century.

Sistrah – Licht GmbH was a German manufacturer specializing in high-quality lighting based on Müller’s patented designs. Their products aligned closely with the Bauhaus ethos of functionalism, emphasizing the principle that form follows function.

The lamp measures 31 cm in diameter (12.2 inches) and has a total height of 130 cm (51.2 inches). It is in well-preserved condition, exhibiting minor age-related wear on the metal components consistent with its period.
