And bang you done! 50 lights for 14.5 all you need is one run !If you are shopiing? hps all the way if the ceilings are 9’ or higher. Run them for a year or two and replace a row at a time with whatever led is the best then. grandmasterleds are the best I see on the market right now and I have tried a few. Double ended hps will be a big upgrade from the single ended and they are cheap right now. View attachment 18796563
