Solaware provides wearable solar lighting to ensure access to safe, healthy and affordable lighting. Their technology offers a source of light to the three billion people that don’t have reliable access to electricity, replacing dangerous and toxic kerosene lamps and candles, allowing people to continue to work, study, and socialise at night.

The unique technology inside Solaware’s lights was developed at the University of Cambridge. The device offers up to five hours of bright light each night whilst being substantially smaller than others on the market.

It can fit comfortably on the wrist, offering portable and wearable lighting. This mitigates the risk of theft associated with other devices and provides a source of light for people displaced from their homes by natural disasters and civil wars, as well as those travelling alone at night.


Solaware is a team of three passionate social entrepreneurs dedicated to providing technology to improve the lives of all people across the world. The team was formed out of the Cambridge Centre for Gallium Nitride, one of the first groups to develop high efficiency white LEDs.

James Griffiths is a materials scientist working in the development of high efficiency light emitting diodes to provide more energy efficient lighting. He is also now developing the solar lighting technology used in Solaware devices.

Thomas Choi is currently researching and developing high power transistors for efficient high power energy conversion. He is continuing to work on the product development.

Shivi Chandna has recently completed her master’s degree in engineering for sustainable development after working on the implementation of sustainable technologies at Qualcomm. She is developing the business and commercialisation strategies at Solaware. 


Solaware’s aim is to ensure that every person around the world has access to safe, healthy and affordable lighting. 

More than three billion people across the world do not have reliable access to electricity. Instead, these people use kerosene lamps and candles. These dim sources of light generate toxic fumes which lead to an estimated 4.3 million deaths each year. Also, the ongoing cost of fuel and candles typically constitutes a large portion of household income in developing countries, trapping people in poverty.

Solaware wants to provide high quality lighting to people to allow people to continue to work, study and night using clean and sustainable solar energy. Their small, affordable devices will help to alleviate energy poverty and give people the freedom to pursue their aspirations.
