Yeelight Jelly 4 Review: Simple Plug-in Night Light with Auto Sensor

Опубликовано 1 мая 2026, 17:15

In this video, I review the Yeelight Jelly 4 Plug-in Night Light — a small and simple night light that plugs directly into a wall socket and automatically turns on in the dark.

It does not need batteries, charging, Wi-Fi, Bluetooth, or any app. Just plug it in, and the built-in light sensor will turn the light on when the room gets dark and turn it off when there is enough light.
This compact night light uses a warm white 2700K light, consumes only about 0.25W, and is designed for soft night lighting in places like a hallway, bathroom, bedroom, kids’ room, staircase, or bedside area.
In the review, I check the design, package contents, real power consumption, light sensor operation, and how well it lights up a dark hallway and room.
Please note: despite some seller titles mentioning a “Human Body Sensor”, this model does not have a motion sensor. It works with a light sensor only.

Write in the comments what you think about the KOWSI KWS-306WF and whether you would use such a 3-phase WiFi relay at home, in a workshop, in a server room, or in an electrical panel. And it will be especially interesting to read whether you see such devices primarily as protective relays or rather as smart devices for monitoring, limiting, and controlling load.
