Be part of the International Lighting Design Family Tree!

The lighting industry is an entangled and complex mesh of entwined practices and people; and five years ago the UK lighting design consultancy Light Collective demonstrated this, at least for the British lighting family, with a colourful graphic showing the interconnections.

Now, Light Collective is keen to move on to the rest of the world: with sponsorship from Ligman and arc magazine they are planning to create an International Lighting Design Family Tree.

It’s based on the International Lighting Design Survey in arc magazine 2019, the biggest yet with almost 1,600 lighting design practices featured; and Light Collective is inviting individual designers to contribute their data and share the companies where you have worked via this link.

Light Collective plans to use this data to create a physical version of the International Lighting Designers Family Tree on the Ligman stand at Light & Building in Frankfurt next March. (If you don’t get around to adding your data online, you can visit and add yourself on to the wall.)
