Not sure what the disagreement is lol

, like you, I thought the H chips were marketed as H just for horticulture market, and for the most part this appears to be the case however, as you have mentioned and confirmed here H chips are slightly more efficient albeit they are the very highest flux bins and the cream of the Samsung 301 series diodes, which technically makes H chips slightly brighter right?
Regarding Anti-sulfurization, my point was not whether B or H have this coating; it was more to do with the fact the Anti-sulfurization coating by design stops corrosive sulphur "Gas" ingress.
Surely if it can stop "Gas" then it will most certainly stop water particles/droplets i.e moisture ingress of the diode, no?
