With JavaScript on, type the light's height above the water and the coral's depth and the page works out a range.
This is an estimate built from a few hobbyists' readings, not a measurement. The range is wide on purpose, because those readings disagree, for some lights by nearly two times, and one owner's corals burned at a step the low end called small. It is for the spot right under the light; anywhere off to the side reads lower. A PAR meter reading beats it every time.
Spectrum read from EcoTech Marine G6 Blue vs G5 Blue graph, as published by Reef Builders (2022-05-18). See the graph. The split between channels is a model fitted to that graph, and it reproduces the graph with an R² of 0.997.
EcoTech Marine's own page for it: Radion XR15 G6 Blue.
Where its PAR range comes from: Low: a single XR15 G6 Blue over a 24 x 20 in tank, read 3 to 15 in deep (ParWise, corrected up 17%). High: Apogee readings under three XR15 G6 Blues at 80% on a 48 x 28 in tank. Mount heights were not given, which is most of the gap.
