We are committed to making the event
as resource efficient as possible.

Our goal is to

  • to offer catering that is as regional as possible,
  • to avoid the use of disposable tableware and bottles,
  • As much as possible, we are saving on disposable printed materials banners, flyers, etc….
  • Instead, we are looking into the possibility of to write on boards with chalk
  • To work with the original materials of the cooperation partners.
  • We obtain moderation materials, such as question cards, name tags, etc.,
    from the remaining stocks of printing companies
  • We ask our visitors to bring a badge from their private collection.
  • We try to record our digital footprint and include compensation in our cost planning.

We look forward to receiving more suggestions on this topic!

OpTecBB e.V. is the competence network for optical technologies and microsystems engineering in the states of Berlin and Brandenburg.

The partner LiTG – the German Lighting Society – based in Berlin, Germany, is a registered technical-scientific association pursuing non-profit objectives in accordance with its statutes. With its more than 100-year tradition, LiTG sees itself as a dynamic network and knowledge platform for all those interested in lighting. It is divided into 16 district councils with about 2300 members.

Gather Around Light – an informal network of people who are enthusiasts for light and darkness: planners, designers, scientists, artists, thinkers, manufacturers, sales and distribution and so-called amateurs.

We organize the monthly Berlin Light Roundtable and regularly initiate events on the topic with cooperation partners; in doing so, we always think outside the box and connect the most diverse perspectives.

In our civil-professional voluntary engagement we show that with passion you can make a difference.



… let’s take a look at the big picture and shape the future together!

How deep Is the ocean - how high is the moon?

intact surroundings
… the basis of our culture and for some cause for a deep feeling of happiness

Where we start from

According to a recent study, light pollution is currently increasing by 10% per year worldwide. At the same time, cities, oceans , landscapes and sink in waste and valuable resources are wasted. By mining primary raw materials, we destroy ecosystems and the livelihoods of peoples.

How deep Is the ocean - how high is the moon???!

Aspects of our reality today.

Reason enough to rethink, to build differently, to plan differently, to produce differently, to illuminate differently.


We Can Do Different. Let’s get going

In the “Environmentally Lighting Symposium”, we look at the topic from different angles.
Join us in a dynamic discussion to find out, where we stand, whatalternative approaches already exist with regard to the avoidance of light pollution and in favor of recyclable illumination. We will show you in which direction we can go together for a paradigm shift in the interaction of nature and industrial culture.

Let’s share our experience. Let’s take the consequences into account. So that we get even better at what we do.
