This study explores the consequences of the adoption of energy-efficient LED lighting in garment factories around Bangalore, India. We find that LED lighting, which emits less heat than conventional bulbs, decreases the temperature on factory floors, and thus raises productivity, particularly on hot days. These significant productivity gains imply high private returns to adopting LED lighting, in addition to its energy-efficient characteristics.
