I have one on the way as well. At $150 with a gooseneck if this thing can really grow anything at around 12" substrate depth its kind of a game changer for cheap high quality lighting on smaller tanks for those who don't like strip lights. As for the comment on led floodlights being a good alternative I think that's a bit ridiculous. I have a 10w flood over my 6gal low tech and while it does work well the quality of lighting you're going to get as far as color rendering and shimmer from the kessil is going to be much nicer. On top of all that its a much more attractive package and I don't have a ton of faith in the longevity of the flood lights. They serve their purpose for the cost but so does a Toyota carolla vs an Audi, both will get you to work but it's all about where you prefer to spend your money. Mine is going to be over a 15.8x12.6x12.6 tank so I will be sure to chime in on how it works out for me.
