* Before setting the current via the DIP switches, confirm that the LED driver is powered off. To make the current setting effective, you need to power on the driver again. (Note: If you do not power off the driver before setting the current, it may cause damage to the light fixture.)
* E.g. LED 3V/pcs: 9-42V can power 3-14pcs LEDs in series, 9-21.5V can power 3-7pcs LEDs; the max quantity of LEDs in series will be subject to the actual voltage of LED.
