Our experiment in Q3 of 2021 shows 2.07g/kWh (Marijuana dried product) production under Lightera® LED grow light G5, which double than 1.05 g/kWh under HPS.
It is clear to us that LED lights convert more electrical energy into light and less into waste heat. In addition, Lightera® LED grow light G5 provides a spectrum that is more tailored to the needs of cannabis being cultivated.

About Spectrum
Light is electromagnetic radiation, and have a range of
frequencies. Light spectrum is a graph of the intensity plotted against the frequency
For all the artificial light sources, LED is the only one of which spectrum can be tailored till now.
LED is a semiconductor light source that emits light when current flows through it.
The color of light emitted from a semiconductor die is determined by the combination of chip materials, or we use a phosphor material to convert monochromatic light from a blue or UV LED to broad-spectrum white light.
Comparison to HPS, we added blue light with peak wavelength 450nm, red light with peak wavelength 660nm and far-red light with peak wavelength 730nm to enhance photosynthesis. Besides, the red light with 700nm was cut down to weaken its negative affection on plant growing.
