Shenzhen Power-Solution (SPS), founded in 2009 in China as an entrepreneurial venture, disrupted traditional lighting markets in African villages with its flagship product, Candles Killer. This solar lamp, priced under $5, replaces hazardous kerosene lamps and has an optimized design (9 components, water-bottle stands). The candles killer solar lamp addresses the critical need for affordable, safe and sustainable lighting for people at the bottom of the pyramid (BOP), a huge market that multinationals struggle to reach. By achieving both low cost and differentiation, SPS created a blue ocean market. The company has made remarkable progress in its mission to provide solar lighting to underserved communities: by 2023, it illuminated over 55 million people across 7.8 million households in 66 countries. Beyond social impact, SPS achieved environmental sustainability at scale, reducing cumulative carbon emissions by 6.7 million tons, the equivalent of planting 368 million evergreen trees. Candles Killer's success led SPS to expand its product line into a solar home system for phone charging and multi-bulb lighting. SPS also introduced Solar Media, a platform with pre-loaded content (medical tips, farming methods, education) to share vital knowledge in remote regions.
