We took the FATPHARM250 to a UK LED research center and they undertook a full spectrometer reading of the light with an UPRtek spectrometer. Here are their findings at a height of 12″ in an ambient 23 °C room.

Keep in mind that PPFD is the Photosynthetic Photon Flux Density defined over PAR 400~700 nm and PFD is the Photon Flux Density defined over 380 – 780 nm (full spectrum) which is beyond PAR.
