Closet sensor light Yeelight A20 20 cm 1.2 W — battery-powered PIR LED, 100 lm, 4000 K, USB-C rechargeable

Yeelight A20 20 cm 1.2 W closet sensor light is a compact, battery-powered motion-activated LED luminaire designed to provide practical hands-free illumination for wardrobes, cupboards and other small storage spaces. With a slim 20 cm length and low 1.2 W power consumption, the unit delivers focused light for night-time access, under-shelf lighting and areas where fixed wiring is impractical.

Advantages

The Yeelight A20 operates from batteries and triggers automatically via an integrated motion sensor, allowing tool-free installation and immediate use without electrical wiring. Its low power draw extends battery life while the 20 cm LED bar provides even, shadow-reducing illumination across closet shelves and folded clothing. The compact design is suitable for discreet mounting and for use in confined spaces.

Suitable for

• Illuminating wardrobes and built-in closets
• Under-shelf or pantry lighting
• Small storage compartments and cupboards
• Night-time corridor or entryway accent lighting where brief illumination is needed

Key specifications

• Length: 20 cm
• Power consumption: 1.2 W
• Light source: LED
• Power supply: battery-powered (no wiring required)
• Activation: motion-activated sensor
• Mounting: surface-mountable for closets, shelves and cabinets

How to use

Mount the Yeelight A20 on a suitable flat surface inside a wardrobe, cupboard or under a shelf using the included adhesive or screws (if supplied). Insert the required batteries following the polarity markings, then switch the unit to the motion-activated setting. The sensor will detect nearby movement and turn the LED on for the preset duration; the light will switch off automatically when no motion is present to conserve battery life. For safe operation, ensure the sensor area is unobstructed and the housing remains dry.

Recommendations

For optimal battery life and consistent performance, place the sensor so motion passes across the detection field rather than directly toward it. Replace batteries promptly when light output dims and keep the lens free of dust to maintain reliable detection.
