Samsung diode lm301h is actually more effective in transferring energy from electrons. It has been confirmed that the introduction of the LM301H is only to differentiate the "Horticulture" market from the general lighting market.


  • Wattage 0.2 W
  • Forward Voltage 2.7 V
  • PPF 0.56 μmol/s
  • PPE 3.10 μmol/J

* PPF: Photosynthetic Photon Flux ** PPE: Photosynthetic Photon Efficacy

Difference between LM301H and LM301B:

Anti-sulfur coating
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.

ECO Farm 480W/650W/1000W/1200W Samsung 301H Chips LED Grow Light For Indoor Plant
