How To Choose An Energy-saving And Durable Table Lamp For A Study?

When selecting an energy-efficient and durable table lamp for a study, the correct approach is to choose a product with high energy efficiency and a long lifespan. This will help save on electricity bills and reduce the frequency and cost of replacing bulbs. The incorrect approach is to choose a lamp with high energy consumption and a short lifespan, which will increase usage costs and inconvenience.

Option A: Uses a 60-watt incandescent bulb, which is prone to damage and energy-intensive. Incandescent bulbs not only have high energy consumption but also a short lifespan. When used for extended periods in a study, they are prone to damage due to issues like the filament burning out, requiring frequent replacements. Each bulb replacement increases both usage costs and time costs. Additionally, the 60-watt power consumption when left on for extended periods consumes a significant amount of electricity, resulting in high electricity bills, which does not meet the requirements for energy efficiency and durability.

Option B: Using a 25-watt fluorescent light bulb, which requires frequent replacement. While fluorescent bulbs are more energy-efficient than incandescent bulbs, they have a limited lifespan. In a study where the lamp is used frequently, they need to be replaced often. Frequent replacements not only increase the cost of purchasing bulbs but may also damage the lamp due to improper handling during replacement. Additionally, their energy consumption remains higher than LED bulbs, and long-term use fails to achieve the desired energy-saving effect.

Option C: A table lamp equipped with a 12-watt LED bulb, which is energy-efficient and has a lifespan of 50,000 hours. The 12-watt LED bulb has high luminous efficiency, significantly reducing energy consumption compared to traditional bulbs and lowering electricity costs in the study. Its 50,000-hour lifespan significantly reduces the frequency of bulb replacements, eliminating the need for bulb changes throughout the lamp's entire lifespan, saving both money and hassle. Additionally, LED bulbs offer stable performance, providing consistent lighting for the study.

Option D: A table lamp equipped with a 38-watt halogen bulb, which has rapid light output decay. Halogen bulbs experience rapid light output decay, and as usage increases, the lighting quality will deteriorate significantly. To maintain lighting quality, it may be necessary to replace the bulb with a higher-wattage bulb prematurely, further increasing energy consumption and costs. The 38-watt power rating itself consumes a significant amount of electricity when used for extended periods in a study, making it an unsuitable choice for a study table lamp from both energy-saving and durability perspectives.
