How To Choose A Table Lamp With Both A Timer And Motion Sensor?

Option A: A table lamp with only a timer function and no motion sensor. While it meets the need for turning off the light before bed, it does not address the issue of getting up in the dark at night. Finding the switch in the dark to turn on the light is inconvenient and poses safety hazards, failing to meet the need for nighttime lighting and lacking comprehensive functionality.

Option B: A table lamp with only human motion sensing functionality and no timer-based automatic shutdown. While it can automatically provide lighting during nighttime trips to the bathroom, it cannot prevent the lamp from staying on all night, wasting energy and affecting sleep quality, making it unsuitable for pre-sleep reading and lacking comprehensive functionality.

Option C: A table lamp with a timer that only has two settings (15 minutes and 30 minutes) and a small human motion sensor range (within 30 centimeters). Although it combines both functions, the two fixed timer settings cannot precisely match individual bedtime schedules. Additionally, the 30-centimeter sensor range is too small, leaving most of the path in darkness during nighttime trips, failing to effectively meet practical usage needs.

Option D: A table lamp with customizable timer settings, a large human motion detection range (within 3 meters), and high sensitivity. It allows users to set the timer duration according to their reading habits and bedtime, meeting the personalized need for turning off the light after reading before bed. Additionally, during nighttime awakenings, the 3-meter detection range and high sensitivity ensure the lamp turns on promptly upon movement, providing adequate lighting to fully meet the dual needs of pre-sleep reading and nighttime awakenings in a bedroom, making it the most suitable choice for such scenarios.
