| Summary: | Electricity consumption from lighting accounts for about 15% of total power demand and 5–6% of greenhouse gas emissions in developing countries. It is therefore a promising avenue to achieve considerable energy savings through technological innovation and upgrading. India has been very successful in recent years with a nationwide roll-out of modern light-emitting diode (LED) applications. This study uses the framework of technology innovation systems to identify the actors, institutions, and processes behind the diffusion of this technology. Our findings indicate that national innovation strategies, along with low-carbon technology (LCT) transfer policies, helped to bring down the cost of LED lamps in a rapidly expanding domestic market. Based on the findings, we further explore lessons for broader issues of low-carbon technology transfer and suggest an emerging intermediate step between north–south and south–south technology transfer.
