  • It can only work in the ambient light less than 20LUX (dark).
  • Time-delay is added continually: When it receives the second induction signals after the first induction, it will compute time once more on the rest of the first time-delay basic (set time).
  • Time-delay adjustment: It can be set according to the consumer’s desire. The minimum time is 10sec±3sec. The maximum is 7min±2min.
  • The switch: The switch is “ON”,“OFF”,“AUTO”.
