Plug-in Nightlight Yeelight YLYYD-0021 with Light Sensor, Compact LED Plug Night Lamp

Yeelight Sensor NightLight Lite is a plug-in nightlight with an integrated light sensor that provides warm auxiliary illumination at 2700 K and 2–10 lm intensity. The device operates directly from mains power (220–240 V) and does not require batteries or charging. Its compact 61 mm diameter and low 0.25 W power consumption make it suitable for continuous automatic use in living spaces and corridors.

Advantages

The built-in sensor enables automatic on/off based on ambient brightness, activating below 2 lux and deactivating above 13 lux, which reduces unnecessary energy use. With a warm 2700 K color temperature and low lumen output, the light minimizes blue-light emission and glare to avoid eye strain at night. The plug design is compact so the device does not block adjacent outlets, and its power consumption of 0.25 W is lower than many similar products.

Suitable for

• Night-time corridor and stairway illumination
• Toilet or bathroom visits during the night
• Children's room or nursery auxiliary lighting
• Bedrooms for gentle orientation light

Key specifications

• Luminous flux: 2–10 lumens
• Color temperature: 2700 K (warm white)
• Rated power consumption: 0.25 W
• Power supply: 220–240 V mains
• Automatic activation threshold: turns on below 2 lux, off above 13 lux
• Diameter: 61 mm

How to use

Insert the nightlight directly into a standard 220–240 V wall outlet and ensure the sensor faces the room area where ambient light level should be detected. The device will operate automatically: it turns on when surrounding brightness drops below the activation threshold and turns off when light is sufficient. No setup, batteries or charging are required; to reset operation, remove and reinsert the plug.

Recommendations

The nightlight is intended for indoor use only. Install in a dry, ventilated location and avoid covering the sensor or placing the device behind objects that block ambient light measurement. For optimal sensor performance, place it where it can directly sense room illumination and away from bright direct light sources.
