The privately owned research companies Lumigreen and Intravision were established in 1998 in aiming to explore new commercial applications of colored lights. The initial technology platform was based on Cold Cathode Light-tubes and electronics, but with the establishment of Eureka research cooperation with Lumileds Lighting (today Philips Lumileds) in 2004, the technology focus gradually shifted towards LEDs.

From 2000 the research and technological development were structured with

Intravision Group as the mother company with 5 subsidiaries:

Colored or Narrow Bandwidth light for applications within biology and biotechnology.

Intravision Aqua AS – Light systems for aquaculture.
Lumigreen AS – Turfgrass growth technology.
Promar AS – (Biotech) UVA- and Blue-light sunscreen produced via GMO Bacteria.
Promar Aqua AS – (Biotech) Natural Astaxanthin produced via microalgae.

Computer controlled color-mixing systems for applications within art and architecture.

Intravision system AS – Computer controlled color light systems.

In 2013 the owners of Intravision Group decided to end cooperation and split the companies in two separate structures.

Lumigreen is commercializing and furthering the research of the light technologies from the former Intravision Group company structure.
