The correct answer is Option 4: 1, 2 and 3. The Bureau of Energy Efficiency (BEE) Star Label is a rating system used in India to indicate the energy efficiency of appliances and equipment. The label is intended to help consumers make informed choices about the energy consumption and efficiency of the products they buy.
1. Ceiling fans: The BEE Star Label can be found on ceiling fans in India. The label rates the energy efficiency of the fan, based on the amount of energy it consumes and the amount of air it moves. The label ranges from one to five stars, with five stars indicating the most energy-efficient fans.
2. Electric geysers: The BEE Star Label can also be found on electric geysers in India. The label rates the energy efficiency of the geyser, based on its performance and energy consumption. The label ranges from one to five stars, with five stars indicating the most energy-efficient geysers.
3. Tubular fluorescent lamps: The BEE Star Label can be found on tubular fluorescent lamps (TFL) in India. The label rates the energy efficiency of the TFL, based on its luminous efficacy, power consumption, and life span. The label ranges from one to five stars, with five stars indicating the most energy-efficient TFL.
In conclusion, the BEE Star Label can be found on all three options given in the question: ceiling fans, electric geysers, and tubular fluorescent lamps. The label is an important tool for consumers to make informed choices about the energy efficiency of the products they buy.
