Thank you very much for viewing this product. This is a circular light with a human sensor, which illuminates the room with daylight white light. It's USB rechargeable, so batteries are not required. ⭐️Easy with a physical switch⭐️ The slide switch is easy for anyone to understand. Unlike models with many button presses, this model simply slides between OFF, AUTO, and ON. Normally, use AUTO for the human sensor light function. ON can be used as a light for finding things, etc. We also have warm-toned lights available, so please take a look. We perform a lighting test before shipping. Due to the low price, it is a new, non-branded product, and there may be some burrs or scratches. However, there are no issues with the sensor or light. Due to the low price, it will be wrapped in bubble wrap and shipped via Yu-Packet Post Mini. - Set Contents: Set of 2 - Usage: Indoor - Sensor Function: Human sensor - Design: Circular - Color Temperature: Daylight white - Mounting Method: Magnetic - Accessories: Charging cord, mounting magnet, mounting iron plate - Examples of Use: Closet, drawers, hallways, etc. We will ship within 24 hours.
