Unique Lighting Control Features


Using solar array voltage to determine day and night, it provides 10 different lighting control options.



By measuring the length of the night,  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 moving 4 night average, and thus 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.
