By now there are tons of threads of people asking about bestva leds, every time the answer seeems to be the same: bestva is same tier lighting as marshydro and most ebay/amazon blurples: wanting in power and efficiency but can definitely grow a plant.
But with proper lighting so accessible (qbs, china qbs, all sorts of easily setup samsung/blux strip lights) why go for sub par?
Also: all of these bestva threads only ever get a page long whereas the quantum board is now over 600 pages; which light do you think is your long term keeper?
