Been looking for par information for an XR15 Pro for a while. Got the PAR meter from the Reef Club and got it myself. The following table is from a JBJ Nano 28 gallon, 18" T X 22"W X 32" D. The light is mounted on the RMS (9" above water) with the 80 degree lens and set at 70%. All readings were taken from about the middle of the tank below the light. Also locations E,F,G, and H are the corners of the tank at sand level. Hopefully you can read my handwriting.
