Reef LED PAR database

PAR at depth, coverage area, and mounting height for every reef LED fixture worth considering. Numbers are corrected for underwater use (MQ-510 calibrated or Apogee 1.32× corrected) and aggregated from Sanjay Joshi's archive, BRS testing, manufacturer specs, and the Reef2Reef PAR database. 20 fixtures indexed.

Pair these PAR numbers with the PAR underwater correction calculator if you're using an Apogee MQ-500 / MQ-200 in-air sensor, and the DLI calculator to translate peak PAR into daily light dose.
