I have issues with the way Danna submitted the testing results for the Aqua Illumination fixture.
1) Who is going to mount their lighting fixture 1" above the water surface? The article says the legs were removed from the AI unit & 1" above the water surface.
2) The PAR charts representing AI vs the tested MH use different colors, giving the illusion the AI fixture has more PAR.
3) As mentioned before. No one who wants good growth is going to use the MH unit used in the comparison.
