Woodlight

Woodlight develops bioluminescent plants by integrating bioluminescence biotechnology into living plants. It describes modifying plant cells so they can produce light via the bioluminescence reaction (luciferase and luciferin), while maintaining the plants’ natural ability to capture CO2. The company frames its approach as a sustainable alternative to conventional lighting because the plants generate their own gentle, diffuse glow without requiring external electricity.

Woodlight positions these bioluminescent plants as suitable for illuminating spaces where soft light is sufficient—such as parks or bike paths as light “markers” in addition to conventional public lighting, and also indoor and urban settings more broadly. For early prototyping, the company says it chose tobacco plants as an initial model due to their compatibility with cellular modifications and ease of cultivation, with other plant species described as already in development.
