HAIR · PURE · LUXURY

PPF (µmol/s) is the total light flux of the fixture — photons per second, regardless of distance or area. High PPF does not automatically mean high PAR in the tank.
PAR (µmol/m²/s) is the area measurement at a tank position. PAR decreases with depth. The LiST Tool calculates the optimal configuration.
PUR weights PAR according to the absorption curve of zooxanthellae. Blue 430–480 nm is weighted more heavily — where corals absorb most efficiently.
LUX measures brightness for the human eye — biologically irrelevant for corals, but useful for visual tank assessment.
