About

Ambiguous White
Ambiguous Midnight

Beyond creating visually captivating and functional lighting, ambiguous is a lighting studio based in Singapore that is guided by ecocentric values. We specialise in integrating solutions that enhance the natural environment through thoughtful lighting design.

Behind The Name

In design, specification and simplification are means of making things easier to use and understand, but they can also create division and bias. Our philosophy is that in ambiguity we find flexibility, diversity, and depth – especially in a material like light.

The richness of life lies in ambiguity.
