Evans Wadongo (born 11 March 1986) is a Kenyan engineer. He is a graduate in Electronic and Computer Engineering from the Jomo Kenyatta University of Agriculture and Technology in Kenya. Evans was born in the Western part of Kenya, in a poor rural area, without electricity and very few schools. Both his father and mother are teachers.

Evans designed a solar lamp which he calls ‘MwangaBora (Swahili for "Good Light") in 2004 as a way to address poor education, climate change, health and poverty in rural areas in Kenya. Evans named the entire project ‘Use Solar, Save Lives’ as he aimed to use solar technology as a way to save lives in the poor communities he grew up in.

In July 2011, in response to the increased publicity from the international community, Evans launched Just One Lamp, a globally-focused campaign that raised funding and awareness for MwangaBora lamps. Evans is now expanding his effort beyond Kenya and bringing his model to other developing nations.

In 2013, Evans Co-Founded GreenWize Energy Limited, a for-profit social enterprise that designs and implements renewable energy solutions.
