There is a post in this thread: http://reefcentral.com/forums/showth...readid=1509727

on RC where a member posted the lengths of the fixtures but those have been the only reported dimensions and who knows how accurate they are.

Great point, but I don't think alot of people would take anyones opinion as gospel. Testing or not, I see grim's work as opinion, nothing else. What i'd like to see more of, especially with t5 lighting is, "This is my fixture, this is my bulb combo, this is a pic of my tank"

To be fair I don't think that Grim ever intended himself to become a definitive source or that he ever tried to represent his results as scientific. I've got the impression more than once that he is uncomfortable with it for many of the same reasons you are.

I think that's fair. I have gotten the same impression from Grim as well. But as you can see in this thread other hobbyists seem to ignorantly (and I mean that in the very literal sense without any offense intended) prop him up as such an authority as to suggest that his "tests" need to be done in order to provide a stamp of approval on anything related to T5 fluorescents. If you look back at his "tests" you'll see they have been wrought with errors (to which Grim has admitted quite admirably). Unfortunately too many hobbyists seem to latch on to the pseudo-scientific "tests" because they appear to be well done without understanding enough about critically appraising research and study design. As someone whose profession is dependent upon critical analysis of research, and as someone who both publishes and critically appraises randomized controlled trials for a living, I can't help but be critical of those "tests". And I simply feel it is necessary for hobbyists to understand that these "tests" and their results are certainly not definitive and should be interpreted with caution.
