Hey Matt,
Already having issues with this light, and its it's not even here yet, lol. They offer reduction end plates but only available at Coralvue, and unfortunately they don't want to sell the kit, despite not one LFS or online vendor in US carrying them. Even though BRS Investigates already mentioned the flaws of the light being too wide for most tanks, spilling light. PAR was much lower than the Aquatic Life hybrid. 10" gap in between t5's is silly! So, thank goodness for BRS working with me, it seems that Coralvue doesn't care. So, if I want the kit, it's going to have to come from Europe, and it appears the Euro models also include acrylic shields. Bummer, I would have likely kept it without the shield, assuming I could aquire the reduction kit

So, looking like I will go with Aquatic Life 36" hybrid, better performance, and less $$$, and including hanging kit, which is extra with Geissemann. I guess I will chalk it up as a blessing in disguise

$360 for the hybrid, roughly $70 for Reducing kit, and another $30 for hanging kit, no shield, which Aquatic Life does not have. So side by side, around $460 for proper sized Geissemann Stellar, vs. $280 for the Aquatic Life. Not gonna happen!
Cheers
