Think i found it, i read almost everything about leds and par/ppf and umols per sec and all that other light jibberish lol, i found the Optic 6, puts out 620 true watts claims it gets 1.5 grams per watt, check it out ledgrowlightsdepot.com
Iām familiar with them, @Alton66 had them and thought they were decent but replaced with other lighting.
