How To Choose An Environmentally Friendly And Energy-efficient Table Lamp?

When selecting a table lamp for the office, prioritize products using LED or other energy-efficient bulbs to reduce energy consumption, lower electricity bills, and promote green office practices.
You need to purchase a table lamp for daily office use. From an energy-saving and environmentally friendly perspective, which of the following table lamps is a better choice?
Answer
C
Explanation
When selecting table lamps for an office from an energy-saving and environmentally friendly perspective, the correct approach is to choose products with high energy efficiency and good environmental performance to reduce office electricity costs and minimize energy waste. The incorrect approach is to choose table lamps with high energy consumption and low efficiency, as this not only increases operational costs but also contradicts the principles of green office practices.

Option A: Using a 75-watt incandescent bulb, which is energy-intensive and has unstable brightness. The high power of a 75-watt incandescent bulb means that prolonged use in an office setting will consume a significant amount of electricity, increasing office electricity costs. Its unstable brightness can also affect work efficiency, such as when handling documents or drawing, where fluctuating light levels can cause visual fatigue. Additionally, the low luminous efficiency of incandescent bulbs results in significant energy waste.

Option B: A table lamp equipped with a 30-watt fluorescent bulb, which has light decay issues. While fluorescent bulbs are more energy-efficient than incandescent bulbs to some extent, the light decay problem worsens over time, leading to a gradual decline in lighting quality. To maintain adequate lighting, bulbs may need to be replaced prematurely, increasing maintenance costs. Additionally, their energy consumption remains higher than that of LED bulbs, making it difficult to achieve energy-saving and environmentally friendly goals in the long term.

Option C: A table lamp equipped with a 15-watt LED bulb, which is highly energy-efficient and flicker-free. The 15-watt LED bulb provides stable and adequate lighting to meet various office lighting needs. Its energy-efficient characteristics can save a significant amount of electricity compared to traditional bulbs, reducing office electricity costs. The flicker-free light effectively reduces visual fatigue among office staff, improving work efficiency. Additionally, LED bulbs do not contain harmful substances such as mercury, making them environmentally friendly when disposed of, in line with green office requirements.

Option D: Install a 40-watt halogen bulb table lamp with low energy conversion efficiency. Halogen bulbs have low energy conversion efficiency, with a large amount of electricity converted into heat and only a small portion converted into light. A 40-watt power rating for prolonged use in an office will consume a significant amount of electricity, increasing operational costs. Moreover, the high heat generated may affect the normal operation of office equipment, posing safety hazards and failing to meet the energy-saving and environmentally friendly selection criteria for office table lamps.
