For the six years, researchers affiliated with Lighting Africa visited Kericho, Brooke and Talek in Kenya to observe trends in the off-grid lighting market. Their initial market survey, which began in 2009, provides a baseline for the types of off-grid lighting products that were available in an urban, a peri-urban and an off-grid market. The researchers returned in 2012 and 2014 to survey all three towns again and observe shifts in lighting technologies and power sources, product sales and revenues, and retailer demographics.
