My new QB style light has a Meanwell ELG-240-48A driver, which has both voltage and wattage adjustment potentiometers. There are conflicting reports about how to dim the lights. Some say use the Vo pot and some say the Io. Originally, the vendor sent me instructions to use the Io. But my Io is stuck. So then they sent me instructions to use the Vo instead.
I'm no electrician, but I'm sure that there must be a right way to do this, in terms of producing the best light, most efficiency, etc. Can someone shed the light of their knowledge on this?
