Features: 1. Use high-efficiency white LED technology: high efficiency, power saving, long life, no radiation, energy saving 2. It adopts advanced human body thermal infrared detection and induction technology, which has the characteristics of high sensitivity, anti-interference, silent, fast response and long sensing distance. At the same time, it does not emit any type of radiation, the power consumption of the device is small, and it is non-contact, which can protect people39;s health to the greatest extent. 3. Lights on when people come, lights off when people go: Optimized induction control design can realize lights on when people come, automatically delay turning off, no need to turn off the switch, energy saving, worry-free, no longer worry about whether you forget to turn off the lights, and liberate yourself . 4. Built-in light sensing device, automatic identification of day and night status, automatic standby during the day, sensing light at night, energy saving. 5. Humanized appearance design, exquisite appearance, fashionable and ultra-thin, 6. Reasonable structure design, cleverly invisible fixing, no screws for installation Notice: Please allow 1-3cm deviation due to manual measurement Actual color may be slightly different from the image due to different monitor and light effect Description: Power supply mode: USB charging Delay time: 15 seconds Power-on self-test time: 15 seconds.
