Well I have to disagree.
Of course if I had 100 identical reef tanks and could randomly assign different lighting units to the different tanks and compare them for PAR and coral growth that would be great. Since no one has the money or time to do that we have to settle for the next best thing. Grim's testing, although imperfect, is a valid source of information. Another source of information is people's experience with a piece of equipment. For example if you read 500 postings stating that brand X skimmer is a good skimmer then you can be pretty confident in buying brand X skimmer. However there won't be much accumulated experience with these new light fixtures until a year or two has gone by.
We lack objective scientific information about most of the equipment we buy. Anecdotal reports by other hobbyists, and testing such as has been done by GrimReefer, is the best we have to go on. And I won't be buying any expensive equipment for my tank unless it has either been endorsed by many other hobbyists, or had some comparative testing done, or both.
