Yes, our lights will work with 110/120 volts and 220/240 volts; PhytoMAX-4 SC models even support 277V, and PhytoMAX-4 SX lights run at 347V-- all you need is the right power cord to plug into the outlet. Our lights come with a heavy-duty 14 gauge 8-foot North American 120V cord, but we have other lengths available for both voltages here on our website.
