It has superior efficiency, excellent distribution, and top-quality components.

I do an unboxing, show the set-up process and run two PAR tests at different hanging heights. The ROI E720 gives us a great chance to explore the grow light physics of changing hanging height. I show how it affects distribution, Usable PPF, PPFD and Photosynthetic efficiency. I think all growers may find it enlightening.
