Understanding Spectrum and Par Reading When it comes to measuring the amount of effective light an LED, HID, and fluorescent light fixture emits for a plant to use, there are two primary measurements that should be read and examined together. First, PAR or Photosynthetic Active Radiation needs to be measured. PAR is essentially a measurement of light emission within the photosynthetic range of 400-700nm. This represents the area of light...
