ECO Farm 120W/125W/240W/480W Waterproof Quantum Board LED Grow Lights With Samsung And Osram Chips

Reflector Cup or Frosted Lens + Reflector Cup type can be optional for 30~50% stronger canopy penetration and evener light distribution than traditional quantum boards. It’s made of Samsung LM301B/LM301H and Osram Oslon SSL 660nm or 660nm + 730nm, creating tailor-made light recipes for faster growing and higher gram buds. It can be waterproof IP65 for safer operation in high humidity environment. Forget the traditional quantum boards, choose the RX-G1910-90 series for your grow tents cultivation.

Remark

Alternating Current -AC vs. Direct Current-DC
The difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single direction, or "forward." In AC, electrons keep switching directions, sometimes going "forward" and then going "backward."
Alternating current is the best way to transmit electricity over large distances.

Preferred plant spectrum, F15 more dark red spectrum 660nm, F16 additional far red light 730nm, more suitable for medicinal plant growth
