How To Choose A Table Lamp With A Human Motion Sensor?

You often need to get up at night to use the restroom. To avoid the hassle of turning on the light in the dark, you want a table lamp with a human motion sensor. Which of the following table lamps with human motion sensor features is most suitable for you?
Answer
D
Explanation
Option A: A table lamp without human motion sensing is inconvenient for people who frequently get up at night, as they must search for the switch in the dark to turn on the light, posing safety risks such as tripping over obstacles. Additionally, it cannot provide timely illumination, failing to meet the lighting needs for nighttime use.

Option B: The table lamp has a limited human motion detection range, only detecting human activity within 30 centimeters of the lamp, making it less practical. When someone approaches the lamp from a distance, it cannot detect and turn on in advance, only lighting up when the person is very close. This means that most of the journey during nighttime trips is still in darkness, failing to effectively address the issue of walking in the dark.

Option C: The human motion sensor has a moderate detection range, capable of detecting human activity within 1 meter of the lamp. This represents an improvement over the 30-centimeter detection range of Option B. However, in larger rooms or when the bed is farther from the lamp, a 1-meter detection range may still be insufficient, potentially resulting in the lamp failing to turn on promptly when someone gets up at night outside the detection range.

Option D: The lamp has a large human motion detection range, capable of detecting human activity within 3 meters of the lamp, and is highly sensitive. It can detect human activity from a distance and turn on promptly after someone gets up at night, providing adequate lighting. Even in larger rooms or when the bed is far from the lamp, it ensures that there is always light when walking, greatly solving the problem of getting up in the dark at night, making it the best choice for those who frequently get up at night.
