main objective of bachat lamp scheme run by ministry of power
Domestic Efficient Lighting Programme "Bachat Lamp Yojana" was a launched by the government of India on 25 February 2009 to reduce the cost of compact fluorescent lamps (CFLs, i.e., energy saving lights) sold to consumers.[11][12] Implemented through the Bureau of Energy Efficiency (BEE) in India's Ministry of Power, the program's goal was to deliver CFLs at the cost of normal lightbulbs.[13] The difference in cost will be covered by the sale of Certified Emission Reduction(CER) Units under the Clean Development Mechanism of the Kyoto Protocol.[14]
3-way lamp The two filaments can be activated separately or together, giving three different amounts of light. A typical 3-way incandescent bulb is a 50 W / 100 W / 150 W bulb. It has a low-power 50 W filament and a medium-power 100 W filament. When they are both energized at the same time, 150 W of power is delivered, and a high level of light is produced. Usually screw-base 3-way bulbs fit into regular Type A sockets. Larger 3-way bulbs (up to 300 W) have a larger "mogul" base. These 3 way bulbs can also come in spiral designs. [3]
