Or one 8' chain of lighting. You will also receive a genuine HLG-150B Meawell driver. This driver is dimmable, so we will be custom soldering a potentiometer. The potentiometer can dim the lights down to about 24 watts (rough calculations). This really helps with electricity usage as you can have the lights close to the plants with low wattage, but if you need the lights higher to cover more area, then you can turn them to maximum wattage (roughly around 154 watts).All connection cables will be included in this bundle package as well. This includes the power cable and 16 gauge connection cable to daisy chain both lights together. The system itself is very expandable and with a larger Meanwell driver you can daisy chain up to four together with excellent results. We are here if you need to expand and can sell you individual 80 Watt bar lights at an excellent price. Finally, if you would like a customized lighting job (see image of 16 bar lights connected together), we can do that for you! Thank you and happy growing!
