Do LED lights require a ballast like HID lighting?

No, LEDs don't require a ballast. HID lights require a ballast in order to generate the extremely high voltage required to initiate the electric arc inside an HID bulb. LED lights operate in a completely different way and don't need a ballast; they do require direct current (DC) but this power converter is built in to our LED fixtures. You can plug our LED grow lights directly into the wall outlet!

PhytoMAX-2 lights also automatically work with any voltage; the most you will need is a different power cord to accommodate a different wall outlet type.
