I am considering adding another LED strip to my tank, fluval flex 32.5 with a fluval marine 3.0. Would running 2 fixtures at 50% have more PAR and give off more heat than say 1 light strip at 100%? I am thinking more in terms of heat because my tank has a tight fitting hood but also do not want to sacrifice PAR. I am not looking for anything exact about this specific light and I am sure there might be some sweet spots between 50-100%, but I am curious in the more general aspects of LED lighting. Thanks!
