In my view the over $1000.00 price niche for lights is reserved for the wealthy, or dedicated fanatical reefers. Either of these groups is likely to go with the fixture that has an established reputation as being a high-end product.

An 8 lamp 48" ATI Powermodule
without lamps is $900 USD from ReefGeek - your only real option for getting a new fixture. You're going to pay the currently hefty exchange rate, duty, brokerage charges, and shipping charges on top of that (in addition to GST and PST which you'd pay for any light purchased within BC or from the US) which is going to far exceed your $1000 ceiling. I guess I'm confused that you take issue with the "over $1000.00 price range" while at the same time saying "or I will go with the PowerModule" when the Powermodule will likely cost around $1300 without lamps and before tax, and you'll end up waiting about 2-3 months to get it.

Obviously there will be severe flaws in any testing of aquarium equipment. The testing is not randomized or blinded. No one has the time or money to hang 200 T5 pendants side by side and grow corals under them for a year.

Obviously no one is going to go to that trouble. The problem is that the "testing" you wanted done by Grim is so far from being even remotely valid or even reliable that it's laughable that you would suggest you would base a purchase decision on his "testing." As far as I know he has one sample of each of the fixtures he tests and a few samples of various reflectors, ballasts and lamps. You keep talking about hanging 200 pendants side by side and growing corals under them for a year but that is so far from the "testing" that Grim does that I'm utterly confused. He measures PAR of lamps and reflectors and takes pictures of the color emitted by lamps. To date I've never seen him perform any comparisons of coral growth or coloration with respect to fixture, lamp, ballast, or reflector design.
