Just a FYI on this fixture:
The product review here-
Product Review: Hagen Fluval Sea LED Light - reefs.com
states that the fixture was checked using a Seneye PAR meter. Unfortunately, this meter is inaccurate.
This statement is taken from a reviewer of the Seneye meter on another site-
It's measuring things that really don't matter. And the light measurements are terribly inaccurate when compared to a real Par meter (I compared vs Apogee and found it to be about 30-40% higher)
, I would not want this over a coral tank, unless it was softies.
