Can you leave a 60watt bulb switched on for 26 days and nights?

Yes, you can leave a 60-watt bulb switched on for 26 days and nights, but it will consume a significant amount of electricity. Over that period, it would use approximately 1,872 kilowatt-hours (kWh) of energy, which could lead to a high electricity bill. Additionally, prolonged use can shorten the lifespan of the bulb and pose a fire risk if the fixture is not rated for continuous use. Always consider safety and efficiency when leaving lights on for extended periods.
