PAR at depth (μmol/m²/s)
| Depth | Center | Edge | Notes |
|---|---|---|---|
| 6″ | 180 | 90 | Supplemental — pair with main fixture |
| 12″ | 100 | 50 | |
| 18″ | 60 | 30 | |

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.
