Hi HF. Thanks for the questions. I think the SYPDR 600 is overkill, as it is used to deliver very high PAR levels in greenhouse applications :-) It sounds like you are mainly concerned with 1) keeping the plants happy and 2) enjoying the colors on your plants. Is this correct? Do you have any mounting height constraints on the lights? Ideally, how high above the plants would you want to hang the lights?
