All readings corrected for underwater use. Center = directly under fixture; edge = at the 20″ × 20″ footprint edge. PAR varies by individual fixture setup, mount type, and tank glass — use these as a sizing baseline, then measure with your own meter.

Next steps

  • Correct your PAR meter reading using the PAR underwater calculator — uncorrected, the Apogee MQ-500 reads about 24 % low underwater (×1.32) and the older MQ-200 about 7 % low (×1.08); the MQ-510 corrects itself.
  • Convert peak PAR to DLI with the DLI calculator — that's the metric corals actually care about.
  • Reference the lighting guide for PAR targets by coral type.
