I've just bought one of these units and was trying to find a few reviews on them before I dropped $3500, however there was nothing online in the way of user reviews so I thought I'd just do a couple of write ups about it for anyone interested in getting one.
I was running Hydra52s before the Giesemann:-

I found these gave out great PAR but the optical angle was poor so I wasn't getting enough light off the centre line, meaning that my Acropora would grow up but probably wouldn't branch out as much as I'd like.
My options were to add another Hydra52 and switch them 90 degrees into parallel or to add T5, in the end the Giesemann pulled me in! so I bought the 1.5m unit which is the same length as my tank.
The 1.5m unit has 4 LED boards totalling 340w and 4 T5 tubes totalling 320w so 660w all up, something to note for you guys from North America is that I think the maximum wattage for T5 tubes in the US Aurora Hybrid fixture is 54w not 80w as in Australia because of the voltage difference.
Day of arrival......

The fixture then sat on my dining table for two days while I tried to figure out the best way of hanging it from my ceiling. The problem being I couldn't find anywhere that gave a definite weight of the light itself. In the end I put a couple of braces across the joists in my ceiling and used 10kg rated spring clips to hold it. Nervous moments when I finally hung it......

Using a cardboard box as a control measure Australian style.....she'll be right!!
