Simple answer is: Plants will grow in any bulb sold in Loew's except maybe a colored one like a green bulb. Certain spectrums are just better used by the plants.
It helps them and they will grow better the more you get those two the 460 and 660 nm spectrums involved in your light system. Some plant are grown in sheds where filter are put over x amount of window panels to cut most of but not all light letting one or both of those spectrums get through to the plants. I have seen pictures of plants grown exclusively under the red lights before.
But know that bulbs that are single spectrum bulbs lack other spectrums that the plant can utilize also.
What are you trying to do/build/get ?
BTW horticulture farms have hundreds of plants and they should know. They are now saying that the 5500K bulbs do better and some shops(horiculture) have them in 2 or 4 ft only now. Better than 6500K.
