Social Impact

The A-Light-S was developed to address the challenges of sustainability with state-of-the-art technology. The best equipment in terms of quality should also be provided to our neighbors in the Global South, especially in rural areas

Existing kerosene lamps are hazardous to humans and our environment, and must be replaced by ecologically compatible systems. Social consequences are enormous due to the versatile possibilities. The users of our lamp enjoy light for reading, cooking or working without any harmful effects to the eyes. Through the acquisition of a solar lamp, users can save on kerosene expenses. Schools and wards can be provided with light by the portable lamps. Users can also charge their mobile telephones without paying fees. The lamp can be delivered as a kit and be assembled locally. The A-Light S has been in use since mid-2011. To date (2020), about 4,500 lamps were assembled and sent out as kits in the Global South.

Future Plans

We would like to promote the distribution of our A-Light S through even more intensive cooperation with even more development aid organizations.

We are constantly working to make the solar lamp even more reliable and effective.
