Which one saves electricity, light strip or desk lamp?

Light strips save more energy than desk lamps. ‌

The power consumption of light strips and table lamps depends on their power and how they are used. According to the information provided, strip lights typically only light up where you need lighting, and will automatically turn off once you leave that area. In addition, the power of light strips is generally low and does not consume a lot of electricity like other electrical appliances. Therefore, overall, light strips are relatively energy-saving‌1. In contrast, the power consumption of a desk lamp is related to the type of bulb used. For example, a 10W energy-saving lamp desk lamp consumes about the same power as a 12W electronic ballast tube fluorescent lamp, while a 15W bulb desk lamp consumes more power than a 12W electronic ballast tube fluorescent lamp‌2. This shows that the power consumption of a desk lamp depends on its specific bulb type and usage scenario.

In addition, the luminous efficiency of light strips and table lamps is also different. The light strip emits indirect light, reflecting light from the ceiling. Its luminous efficiency may be low, and the actual brightness of the same luminous flux will be much lower. This may mean that although the light strip has a lower wattage, it may not actually provide as much lighting as a desk lamp‌3.

To sum up, although desk lamps and light strips each have their own uses and advantages, from the perspective of power consumption, light strips are relatively more energy-saving due to their lower power and usage methods.
