Hi everyone, i've been a lurker for quite a while here and seeing more and more grower switching to LEDs!
I'm in the process of upgrading my old 250watt HPS grow light to a quantum board and was originally looking at the samsung lm301b diodes but while I was researching I learned that Samsung has the newer lm301h diode.
It seems like it makes sense to buy the lm301h diode because they have improved light spectrum and intensity, I found Niemi LED who sells them https://niemiled.com/product/lm301h-260w-niemi-led-quantum-board/
I'm not sure of the difference between the two types of diodes TBH< is all confusing shit lol
The samsung website might be able to help you with that? But still, confusion lol

the newer chips are slightly more efficient.
It depends how much extra they are charging for the newer ones against how much extra ppfd they give really.
Most people i know have stuck with the older ones for now as the extra cost isnt really worth the efficiency savings.
