your GE Cool Whites will serve as your veg lights, high spectrum ... the other two I am not sure of ... if you need more lamps, WalMart, etc carries GE Cool Whites for veg, and the GE Kitchen&Bath, would serve as your lower spectrum flowering lights ... my area pays about 11 cents a kilowatt, so your present lamps on an 18-hour schedule, every day, would run about $14.75/month ... hope any of that helped ... :smokin:
