Abstract: The research aims at finding out the factors that drive and the factors that inhibit the adoption of LED lighting by households in India. A theoretical model of drivers and inhibitors is developed for the empirical study, based on theory of planned behaviour. Apart from the three basic constructs of theory of planned behaviour, some more variables are included in the model. A structured questionnaire was administered to the households in six largest metro cities of India. The sample size of the study is 555. For data analysis, partial least square-structural equation modelling (PLS-SEM) technique is applied. The study also makes importance-performance matrix analysis to further strengthen the findings. Aesthetics, attitude, perceived behavioural control, and subjective norms proved to be the most influencing factors of purchase intention of LED, in that order and showed a positive association with purchase intention of LED. Only personal moral norms showed an insignificant impact. Inertia turned out to be the inhibitor of purchase intention with a negative relationship, as per our assumption. The study also revealed that, perceived cost which was assumed to be an inhibitor is not an inhibitor.
