All readings corrected for underwater use. Center = directly under fixture; edge = at the Supplemental — 24″ bar 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 — Apogee MQ-500 / MQ-200 in-air sensors under-read by ~25 %.
  • ▸ 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.
