Round USB Rechargeable Motion Sensor LED Light

Sleek, minimal, and functional: this round disc light offers discreet, automatic illumination wherever you need it. Designed to be USB-rechargeable and with a motion or ambient light sensor, the unit delivers purposeful light only when required. Its simple shape and low-profile design make it ideal for closets, under cabinets, hallways, bathrooms, or as a night light. The package includes the round LED unit, a USB charging cable, and a mounting (adhesive or magnetic) backing plate to affix it to walls or ceilings.

Key Features

• Motion / Proximity Sensor Activation
  The light turns on when motion is detected within a set range (typically up to 2–3 meters) and turns off after a delay when movement stops. Such sensor-activated lighting helps conserve battery and energy. 

• Light / Ambient Sensor / Auto Mode
  In some modes, the light only activates in lower ambient light (at night or in dim settings), avoiding turning on when the surroundings are already bright. (Night mode vs all-day sensing mode). 

• USB-Rechargeable / Battery Powered Design
  The included USB cable lets you recharge the internal battery. No need to frequently replace batteries. 

• Round / Slim Profile with Magnetic / Adhesive Mount
  The circular LED unit is slim and lightweight. It is designed to be mounted via adhesive, screws, or a magnetic mounting plate, allowing easy removal for charging. (The image’s included mounting plate suggests such design).

• Multiple Lighting Modes / Dimming
  Some models offer selectable brightness levels (low / medium / high) or stepless dimming, and possibly multiple color temperature options (warm / cool white). 

• Timer / Auto-Off Delay
  After motion ceases, the light may stay on for a set period (e.g. 15 / 30 / 60 seconds or more) before turning off. This provides convenience for walking through a space. 

• Energy Efficient LED Light Source
  Uses low-power LEDs for efficient illumination. Because of the sensor-triggered operation, the unit remains off most of the time, extending working life.

• Front / Disk Face
  The circular diffuser covers the LED area, likely to produce even, soft illumination. The center may have the motion-sensing aperture (a translucent or clear dome) for detecting movement.

• Mounting Plate / Backing
  The square / diamond-shaped plate suggests a detachable mounting method: adhesive tape backing or a magnetic plate that the disc adheres to, facilitating removal for charging.

• Charge Cable
  A USB cable (likely micro-USB in your image) is included, showing that the unit recharges via a standard USB port rather than non-removable batteries.

• Edges / Sides
  The edge is thin, with minimal protrusion, giving a low-profile design. The rim likely contains the LED and light diffuser components.

• Back / Rear Side (not shown, but implied)
  Likely has a socket or port (micro-USB / USB-C) recessed or with a cover. Also possibly has mounting magnet or adhesive patch.

Usage Scenarios & Advantages

• Closets, Cupboards, and Wardrobes
  The sensor triggers the light when you open or walk near, providing just-enough illumination in small enclosed spaces.

• Under Cabinets / Workbenches
  Mount it under a shelf or kitchen cabinet so that it lights up when your hand / body moves nearby, useful for night food prep or work.

• Hallways / Stairwells
  Helps avoid switching full lights at night. As you approach, it lights up the path temporarily.

• Night Light for Bedrooms / Bathrooms
  Gentle illumination to navigate at night, without glaring overhead light.

• Emergency / Auxiliary Lighting
  If main lighting fails, this can act as a backup sensor-activated lamp.

Advantages:

• Low power use due to sensor-only activation

• No wiring needed (portable / rechargeable)

• Easy mounting and removal

• Automated operation (hands-free)

• Slim aesthetics, unobtrusive presence
