PAR (Photosynthetically Active Radiation) is what causes photosynthesis (your plants growth) and happens when your plant consumes photons of light wavelengths between 400 and 700 nanometers. See the graph above! Why is PAR Important? Simply put, grow lights beam out lots of different light wavelengths at your plants. PAR light is the wavelengths of light within the visible range of 400 to 700 nanometers (nm) which drive photosynthesis (Figure 1). PAR is a much used (and often misused) term related to horticulture lighting.

Use PAR bulbs when attempting to put a focused beam of light on an object such as in track lighting or illuminating artwork. PAR is essentially a measurement of light emission within the photosynthetic range of 400-700nm. This represents the area of light that plants use for photosynthesis, or to grow. PAR is measured by the amount of micro moles of light per square meter per second. Although PAR is a key measurement, it only tells one part of the story. Lighting terms can be confusing.

Put simply, it is possible to have a light with a lower PAR number that will grow plants better than a light with a higher PAR number.
