Photosynthetically active radiation - Wikipedia

Chlorophyll, the most abundant plant pigment, is most efficient in capturing red and blue light. Accessory pigments such as carotenes and xanthophylls harvest some green light and pass it on to the photosynthetic process, but enough of the green wavelengths are reflected to give leaves their characteristic color. An exception to the predominance of chlorophyll is autumn, when chlorophyll is …

PAR and Lumens – Compare LED Grow Lights

First, PAR only includes light in the visible spectrum (400-700nm) and does not include UV or IR that a light may put off, even though this light is beneficial to plants. If lights are being compared in terms of PAR per watt, the lights which include UV and IR will be unfairly penalized, even though these lights will probably grow plants much better!
