Launching the world’s most affordable solar-powered light


In July 2015 the design-innovation team I built & led at d.light, a Stanford d.school born global social impact enterprise, launched the game-changing A1 Solar Lantern. To date the most affordable high quality solar-powered lantern in the world, the d.light A1 allows virtually everyone to afford free & safe electric light.

During his recent visit to Kenya U.S. President Obama visited the d.light exhibition at the Entrepreneur Summit in Nairobi, experiencing the simple yet deep power of the d.light A1 Solar Lantern first hand. Seeing & feeling President Obama’s excitement for the A1 Solar Lantern was one of the personal highlights of my professional career so far. Only the tremendous joy I have seen in the eyes of women, men & children when making use of a product like the A1 Solar Lantern for the first time has excited me more.

2 billion people in the world live without power

Today, about 2 billion people in the world live without access to reliable energy. For most of them their only light source are lamps using kerosene, which not only burdens users & their families with a high and recurring financial cost, it also has tremendous health risks due to its toxic fumes and inflammability.

In 2006 Stanford d.school alumni of the Entrepreneurial Design for Extreme Affordability program Sam Goldman and Ned Tozun set out to eradicate the need for kerosene as a light source forever by founding d.light, a global social impact enterprise delivering affordable solar-powered solutions designed for the people in the developing world without access to reliable energy.

In 2008 d.light launched it’s first commercial solar-powered lighting product, the d.light Nova solar-powered lantern — bringing safe, bright, clean light to people around the globe. But the Nova did not stop there. In addition the solar lantern stored enough solar energy to provide it’s users with the ability to charge their mobile phones.

This ground-breaking product has since become an icon of the ever-growing solar-powered lighting & energy revolution Jeremy Rifkin aptly described in his book The Third Industrial Revolution. The Nova has made it into influential publications such as the wonderful book A History of the World in 100 Objects by the British Museum’s director Neil MacGregor. The book masterfully describes the world and human condition by exploring 100 exemplary physical objects of impact. MacGregor & his team chose the d.light Nova as their 100th object — a hopeful outlook into a brighter future for the world, powered by the sun.

Human-centered innovation by Design

Since launching their first product d.light has sold over ten million solar light and energy products in over 60 countries, improving the lives of over 50 million people. The company is committed to reaching 100 million people by 2020.

In early 2014 I was honored to join the d.light executive team as VP Global Design with the task to build an in-house human-centered design innovation group, to develop a next generation product line by integrating brand, product and service development practices into a coherent & consistent capability at scale.

A little more than a year later d.light launched the game-changing d.light A1 Solar Lantern, stemming directly from the product pipeline the design innovation group built during my tenure. Radically simple to use, of high material quality, and ultra affordable the no-maintenance, water, heat and impact resistant product competes directly with the recurring cost of kerosene — by retailing at only $5 USD.

Bringing an ultra affordable yet high-quality solar-powered light to virtually everyone in the world in less than 18 months was not an easy journey, and would not have been possible without the amazing collaboration, dedication & hard work of the entire d.light team working 24/7 in East Africa, South Asia, China and the US. I also want to mention the tremendous support of d.light’s investors, the close partnership with IDEO.org during the value-centered product design & business modeling process, and last but not least the numerous families in East Africa and South Asia who invited the team into their homes to learn from and with them.

Towards a brighter future

British Museum director Neil MacGregor closes his aforementioned 700-page book with a wonderful rational why he & his team chose a solar-powered lamp to sum up the world’s history in 2010 — he writes: “How should this history of the world end? What single object can possibly sum up the world in 2010, embody the concerns and aspirations of humanity, speak of universal experience and at the same time be of practical, material importance to a great many of us in the world now? […] So, for our 100th object we haven chosen a generator of electricity that could give the 1.6 billion people without access to an electrical grid, the power they need to join this global conversation. But it does much more. It gives them a quite new level of control over their environment and could transform the way in which they can live.”

MacGregor’s statement from 2010 has lost nothing of it’s power in 2015, reminding us all: We are still experiencing the infancy of an inevitable global energy revolution, which will continue to be scary for some, and exhilarating for others!

You can support d.light’s mission by buying an A1 (or two) for $5 on Amazon.

Onwards & upwards towards a brighter future for us all,
