Product Description

  • Using solar array voltage to determine day and night, the SunLight provides 10 different lighting control options.
  • By measuring the length of the night, the SunLight’s ON/OFF/ON options provide the capability to turn on the light at sunset, turn off the light after 3 to 6 hours, and then turn on the light again for 1 or 2 hours before sunrise.
  • The length of the night is calculated by taking a 4 night average, and thus it automatically adjusts for seasonal changes in the length of the night
  • The test button helps the installer by blinking the red LED to confirm correct selection of lighting control option, and also turns on the light for 5 minutes to verify that the light is operating correctly.Timer accuracy is within 2 seconds.
