Great value 2-piece set for 1800 yen. This human sensor LED light turns on in dark places. It's a multi-type LED indoor sensor light that automatically turns on when the sensor detects human movement. It automatically turns off after 25 seconds when no one is present! The time is longer for the plug-in type. It doesn't turn on in bright places, so it doesn't use extra electricity. The human sensor is highly sensitive. This human sensor light is designed to be used simply by plugging it into an outlet. There's no need to attach it with tape or screws. Also, it weighs only 40g, making it ultra-lightweight, and can be used facing up or down so it doesn't block other outlets. Of course, the plug-in sensor light also complies with PSE safety standards, so you can use it with peace of mind without worrying about fire or electric shock risks. You can choose your preferred brightness for this human sensor light depending on the scene you use it in. You can choose from two color variations: daylight white or warm white, to suit your needs. This plug-in sensor light is designed in an ultra-compact round shape. Therefore, even if you install the sensor light, the area around the outlet will remain tidy, and you won't have to worry about bumping into it while walking. Despite this compact design, it provides enough brightness to illuminate your feet properly. Since it's a plug-in sensor light, there's no need to replace batteries, and you don't have to worry about it getting dimmer due to aging or wear and tear. Basically, we cannot ship on weekends and holidays. Thank you for your understanding and purchase.
