Product Problem

LM301H has higher photon efficiency than LM301B. The LM301H’s chip is optimized to convert electrical energy into photons more efficiently.
Especially, LM301H is vulcanized for moisture resistance, which minimizes light loss, provides more light to plants, and increases durability when exposed to moisture.
That is to say, using LM301H not only makes obtaining higher yield and quality easier but also prolongs the use time of the grow light so that growers can produce more high-quality crops at a lower cost.
