Arborlight, a US-based lighting company, has raised $1.7m from a partnership including Michigan Economic Development Corporation-funded Michigan Angel Fund.

The Michigan Angel Fund was joined in investing by the Michigan Pre-Seed Fund. Arborlight is a spinout from the University of Michigan’s Office of Technology Transfer department.

Arborlight has created artificial lighting that mimics natural light in realtime. This allows the company to install “skylights” in rooms that have no access to the roof of the building.

Skip Simms, managing director of the Michigan Angel Fund, said: “Arborlight’s potential is impressive, and the company is an exciting example of how technology can be incubated in a university setting, and progress forward and have real economic impact.”

Arborlight plans to use the funding to continue the commercialisation of its product.
