I think that there are mixed reviews about LED lighting. I have it in my 20 gal, but it came included. I haven't experienced anything noticeable yet with my plants. It is lower lighting than I had previously and my vallisneria grows slower. I've had it since February, so it may still be too early to come to a conclusion. Apparently, according to others, to switch to LED is pricey. This I can't comment about because I did have it included.
