New Delhi: A day after the Nobel Prize in physics was won by the scientists who invented blue light-emitting diodes (LEDs), the power ministry Wednesday launched a business model enabling the sale of LEDs to households at Rs.10 against the market price of Rs.400.

"The Bureau of Energy Efficiency (BEE) together with the Energy Efficiency Services Limited (EESL), which is a joint venture of four central public sector undertakings in the power sector, have worked with electricity distribution companies (discoms) to develop a business model under which EESL procures LED bulbs in bulk and sells them to households at Rs.10," an official release here said.
