There is a guy on ReefCentral, I believe GrimReefer is is name, who has tested various T5 units and bulbs. I have a T5 Tek-light and I was hoping to upgrade to an ATI Powermodule. If you can get your lights tested and they stack up to the Powermodule then I would be interested in getting your lights. Quite frankly for a big investment of money on an item I will keep for at least 5 years, I won't be buying without some head-to-head comparison testing.

Once launched light units will be provided to dealers for reviewing and no doubt we will off one unit up to the canadian market and the USA market for public review also

Please dont all start putting your names in the hat as we are a bit off that point at the moment

Can you give me a rough timeline? Originally it was posted that they would be released in January. I know Fauna Marin has had some issues with delayed releases in the past.

As far as GrimReefer's "testing" goes I'd forget it. If you look back on the history of the "testing" done by Hahn and Grim on RC you'll see that they've made so many mistakes that it's impossible to draw any conclusions from their results. For instance, Grim recently found that he wasn't properly handling the T5 lamps correctly and providing sufficient settling and burn-in time when testing the lamps. Prior to that he reported that ATI lamps had "the best" PAR. Now he's having to re-evaluate things. Additionally, he and Hahnmeister incorrectly assumed that T5 lamps required cooling along the length of the lamp. Now they (and we) know that there's a cold spot that needs cooling and nothing else. They also thought that keeping things as cool as possible was the best idea - now they know that overcooling the lamp drops its output.

That's why I laugh when hobbyists perform "tests" of things. Unfortunately those "tests" lack adequate control and often lack sufficient validity. To this point the only test results I'm at all interested in seeing are those by Sanjay if he ever publishes them.

This is why testing will not be done initially by hobbyists but instead dealers that carry more than one type of fixture

The tubes fitted will be of course Fauna Marin Aqua Science or theyre new generation if ordered with tubes, standard will be minus tubes

Dates, they are already in the process of manufacture, and any delay will be due to santa, but I am working hard to get round that one.

First batch will be as follows

24w 4 tube
39w 6 tube
54w 8 tube
80w 10 tube

Dimmable yet to be assigned as we are still testing ballasts.

Dimmable will launch after standard

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.

Does that mean these are discontinued?
