Difference between LM301H and LM301B:
According to the data sheet, the LM301H LED has the same electrical and optical characteristics as the LM301B variant. It is available in different colour temperatures from 2200K to 6500K and in colour rendering index CRI 70-90.
Depending on who builds the light you are looking at 2.7-3.10 μmol/J for the lm301h. The lm301b tops at about 2.7-2.8. So there is a difference but it's subtle.
So next I will recommend you several best Samsung LM301H LED grow lights.
