colegota Wow, 3400lm is massive. Well, suggestion is not easy to make. Best would be to buy all of them and test (joke). For me 6500K tubes work out fine because I nainly got them for seedlings until I can get them into greenhouse and outdoor bed. As far as people say that have tested lights for pure indoor growing (peppers/weed): (1.) sodium-vapor lamp (2.) flourescent light tubes (3.)
LED ... in that order referring to quality of plants. Every solution has pros and contras like price, energy consumption, heat emission, quicksilver, lifetime etc.
