Just got my Phlizon FD-4500 up and running (table grows) It will do the job, but the ViparSpectra KS series definitely shows better build quality/fit n finish as well as PPFD/power efficiency. The older LM281B diodes in the FD-4500 also prove to be less efficient based on heat/PPFD per watt as well. The aluminum bars are approaching 120°F with only 345W input (6 on the 1-10 dimmer).
For reference, my KS-5000 in the tent is currently @ 75% (385W) and the aluminum bars are only at a mere 88°F LOL. It’s also putting out almost 125 more PFFD at the same height from the canopy.
Carry on. :).
