The measurements are compared to the benchmark quantum sensor for measuring PAR from Apogee which costs about $500. The results are surprisingly accurate. - Source: Internet
  • PPE does not include the photons outside the PAR range. Wavelengths outside of the PAR range like far-red (FR) have proven to have a positive effect on growth and steer morphological responses of plants. The efficacy of light containing FR is lower than the efficacy of light sources emitting only blue and red light when measured as PAR photons per wall-plug energy consumption, even if they may give better results in plant biomass production and healthy growth. - Source: Internet
  • PPF is an important metric for calculating how efficient a lamp is at converting electrical energy into photons of PAR. Nonetheless, it is of essence to note that PPF does not tell you how much of the measured light actually arrives at the plant canopy. PPF measurements used to describe light sources should be done in specialized light laboratories using appropriate equipment such as light sensors connected to integrating spheres or goniometers. One recommended way is to use a light company that uses third-party testing. - Source: Internet

Our ILT800 belt radiometer is self-contained and has specific spectral response models available. - Source: Internet
  • The easiest way to understand how light is measured is by picturing the typical light bulb with a filament that heats up producing light (Incandescent if you read the previous section). The filament is the source of the light and is at the centre of a sphere with light being emitted in every direction. The total amount of energy of all the light produced is known as the “luminous flux”. - Source: Internet
