Share your good light experiences with us!

We are always looking for people to share their lighting experiences with us. So, if you want to spend 30 days in good light, outside, in your office or home, contact us to participate, share your story or tag us in your posts on social media about good light. If you want to participate visit our 30 days good light experience page to learn more about the experience or read stories from other participants.

We offer several options if you want to participate in the 30-day experience:


A free solution and very healthy, just enjoy the outdoors for at least 2 hours a day.


A simple and affordable solution to get started. You have to get used to the brightness, but it does the trick.


For special participants, we also offer several lamps that can be borrowed:

  • Sparckel

  • Wirklicht

  • Waldmann

  • Brainlit

Of these options, only a few lamps can be borrowed for 30 days. But feel free to write why you want to try one of these lamps for 30 days and how you will help us spread the word.

More info at my 30 days experience

Don't want to join the 30-day experience but just want to keep us updated on your good light situation? Even if you don't spend most of the day in good light and experience the disadvantages of staying too long in a room that is not adequately lit, let us know! Tag us @goodlightgroup or contact us at
