I would like to compare LED-PlantBars to high-pressure sodium lamps. What is the micromols per square meter per second (μmol·m-2·s-1) of photons, or the PAR watts/square meter of each bar?
Direct comparisons are not possible since LED-PlantBars only emit those light wavelengths needed for plant growth and health. Traditional white-light-based growing lamps were originally designed to accommodate human vision and light up warehouses and factories. PAR meters are of relatively little use as a measurement of light that plants really need. The typical μMols of LED-PlantBars is: 44.0, measured @ 18 inches distance from the middle of the bar.
