There is a flip side. My 60g ensemble came with two T8, 15w, 18" lights in the hoods - Not stamped but I think they are 4100k~. Not much light for a 48"x24"x24" tank. So on the one hand, these lights would stink for plants. On the other hand, my plastic plants don't need much, the lighting is great for viewing, I never have any algae really and the tank is lit about 10+ hours a day.
But I'd agree that you'll likely pay a premium if you get lights at the fish store. The big box, hardware, or wally world will have the day bright lights at a much better price - as mentioned, 6500K + is about right. Some are actually labeled as aquarium plant lights, but always good to check the kelvin value to be sure.
