I think it certainly would help. One thing to keep in mind with some LED lights, is the true wattage is often significantly lower than the one they put in the title. I started out growing with a "600W" purple or "blurple" light which actually only pulled a little over 100W at the wall. I could grow and harvest four plants with no issue. But, the flowers were small, wispy. and probably not living up to their potency potential.
Unless something really bad happens, I think you'll get through flower. Lights are extremely important. But, there are plenty of other factors which play into the kind of final product you will end up with.
