Characteristics of qualitative study participants
A summary of characteristics of interview participants is shown in Characteristics of study participants*SD – standard deviation, LPG – liquefied petroleum gas*Only women were recruited for this study.Sensor-based measurements of daily lighting use for primary kerosene lighting users showed that prior to the intervention, average daily lighting use was 2.3 (interquartile range (IR) = 1.8-2.9) hours, whereas after the intervention, average daily lighting use was 8.3 (IR = 5.1-11.5) hours a day. In mixed effects models, introduction of the solar lighting system increased daily household lighting use by 6.0 (95% confidence interval (CI) = 4.0-8.0) hours a day, supporting the hypothesis that significant light rationing and suppressed demand was present at baseline prior to the introduction of the intervention solar lighting system.
