Energy Conservation

Statement 1 is correct. CFLs produce light through the ionization of mercury vapor which, when it collides with the phosphor coating of the bulb, generates visible light. On the other hand, LED lamps produce light using semiconductor material. Statement 2 is incorrect. The average lifespan of an LED lamp is much longer than that of a CFL. While the lifespan of a CFL is around 8,000-10,000 hours, an LED lamp can last up to 50,000 hours. Statement 3 is correct. LED lamps are more energy-efficient compared to CFLs. Despite their higher initial cost, LED bulbs are more cost-effective in the long run due to their higher energy efficiency. Therefore, statements 1 and 3 are correct.

We can find the Bureau of Energy Efficiency (BEE) Star Label on all of the following options: - Ceiling fans - Electric geysers - Tubular fluorescent lamps The BEE Star Label is a program that promotes energy efficiency in India by labeling appliances and electronic devices based on their energy consumption. Many different categories of appliances are covered under this program
