Stories
Stories from the light
From Johannesburg and the road.
- Brand film The film Watch the film · 1:23
- October 2026 Riders of the Sun They meet to ride. We brought SOMOs. An evening about a light that adapts to whatever is needed — even when it's improvised.
- Story Our story From an idea against candles and paraffin lamps to a solar factory at Victoria Yards — told from Johannesburg.
- Story Into the open From candle replacement to a night by the lake: why our light belongs outdoors — and what it has to prove out there.
- Story Why Sonnenglas? You can buy a solar lamp at the discount store for next to nothing. So why a Sonnenglas? Our honest answer.
- November 2026 The light that was there: making our brand film Our brand film won a craft award for its direction at the IDIDTHAT Craft Awards. Friends of ours shot it on a journey through South Africa and eSwatini — with nothing but the light that was there.
